    Autoimmune hepatitis (AIH) is an autoimmune liver disease that is characterized by a progressive destruction of the liver parenchyma and the development of liver fibrosis. We aimed to examine the relationship between circulating cytokines/chemokines and the Mac-2 binding protein glycosylation isomer (M2BPGi) levels in Japanese patients with autoimmune hepatitis (AIH). We investigated the relationship between circulating cytokines/chemokines and M2BPGi levels in Japanese patients with AIH. Seventy-seven patients with well-documented AIH were enrolled in the National Hospital Organization (NHO)-AIH-liver-network database. We measured the serum levels of 20 cytokines in 31 selected AIH patients before and after steroid treatment using multisuspension cytokine array. Eleven cytokines and soluble adhesion molecules were increased in untreated AIH patients compared with treated AIH patients. Among these cytokines and soluble adhesion molecules, soluble intercellular adhesion molecule-1 (sICAM-1) and interferon-g-inducible protein 10 (IP-10) were most downregulated by steroid therapy in AIH patients. We measured serum sICAM-1 and IP-10 by ELISA and found the levels were significantly higher in AIH patients (n = 77) compared with chronic viral hepatitis C patients (n = 32). Furthermore, there was a positive correlation between sICAM-1 or IP-10 and alanine aminotransferase, total bilirubin, and circulating M2BPGi levels. M2BPGi levels were increased in AIH patients with high stages of liver fibrosis. Additionally, M2BPGi levels were correlated with the histological grade of inflammation in AIH. Circulating M2BPGi levels were significantly reduced by steroid treatment in AIH patients. sICAM-1 and IP-10 are useful markers to assess immune-mediated hepatitis activity in AIH and they correlate with circulating M2BPGi. Serum M2BPGi levels increased in untreated AIH patients with active hepatitis and were decreased by steroid therapy. M2BPGi reflects autoimmune-mediated hepatic inflammation as well as liver fibrosis.

    To be a moral agent is to bear its own responsibility which others cannot take for it. We hold that such irreplaceability consists in its having an inner world to which others cannot have direct access. The purpose of this paper is to propose, as a means of gaining support for our thesis, an experiment - a psychological one in which to assess to what degree we can attribute moral responsibility to a robot. Furthermore, we explore the possibility of a society where humans and robots coexist.

    Vigilance in animals is an important means for predator detection. Animals living in groups reduce their predation risk as more individuals are present. In contrast to most other animals studied, many studies on primates do not support the prediction that individual vigilance will decline as group size increases. For animals to obtain visual information during vigilance behaviour, their eyes must be open. Therefore, if animals are able to perceive differential risk of predation, the inter-blink interval (eye-opening) should increase, and the blink duration (eye-closure) should decrease under higher predation risk. We tested this prediction by measuring inter-blink interval in wild anubis baboons (Papio anubis) in peripheral and centre individuals within a group, and between larger and smaller groups. We found that the inter-blink interval for young males, often located at the front edge of the group, was longer than that of adult males, adult females, and young females, often located in the center of the group, and that the inter-blink interval for adult males was longer when the group was smaller. These results suggest that inter-blink interval can be used as an indicator of primate vigilance toward predators.

    Lisa Feldman-Barrett, who has promoted a psychological constructivism theory of affect, recently proposed the Embodied Predictive InteroceptionCoding (EPIC) model of affect, based on the perspective of predictive coding. The theoretical framework of predictive coding argues that the brain creates inner models that can provide predictions for perception and motor movement, and that perception andbehaviors emerge from Bayesian computations rooted in these predictions. The EPIC model expands this framework to interoception, which is perception of the inner body, and tries to explain the phenomena of affect as integrative experiences based on interoception. This perspective provides important implications for understanding issues of the brain–gut axis and its impairments.

    Reconciliation is an integral part of our social lives. Nevertheless, if a victim perceives the risk of further exploitation by his/her transgressor as non-negligible, the victim may well have difficulty forgiving the transgressor. Therefore, a key ingredient of reconciliation is the transgressor's sincere apology. Theoretical and empirical studies have shown that transgressors can make their apologies credible by incurring a substantial cost. Therefore, we hypothesized that costly apologies, compared to non-costly apologies (i.e., simply saying “sorry”), would effectively communicate a transgressor's conciliatory intention. In a functional magnetic resonance imaging (fMRI) study, participants were asked to imagine a friend committing a mild interpersonal transgression (e.g., standing up the participant) and then apologizing in a costly fashion, apologizing in a non-costly fashion, or not apologizing at all. Compared to non-costly apologies and non-apologies, costly apologies (signals of conciliatory intention) more strongly activated the theory-of-mind network (i.e., bilateral temporoparietal junction, precuneus, medial prefrontal cortex). Moreover, we did not observe any significant differences in brain responses to non-costly apologies and non-apology controls. These results underscore the importance of costly signals in human communication and in human peace-making in particular.

    Although previous studies have revealed the role of oxytocin (OT) in parental behavior, the role of OT has not been investigated through the direct assessment of prefrontal brain activation during parenting. By using functional near-infrared spectroscopy, we aimed to show the relationship between parental [maternal (N = 15) and paternal (N = 21)] OT levels and the activation of the prefrontal cortex (PFC), while holding their infants after separation. Baseline OT levels were measured in the subjects' saliva samples before the experiment. Prefrontal brain activation was assessed in participants sitting alone on a chair (i.e., separation from their infant for 120 s) and during the target period (i.e., holding their infant for 45 s), which was done in triplicate. The oxygen hemoglobin (oxy-Hb) dissociation curve significantly increased in 9 out of 22 channels on the PFC when maternal and paternal samples were combined. However, only the fathers showed a correlation between salivary OT and oxy-Hb signal. Furthermore, while holding their infants, high-OT fathers showed left hemispheric dominance compared to low-OT fathers, while high-OT mothers showed right hemispheric dominance compared to low-OT mothers. This study showed that fathers with high-OT levels showed neural activation with left hemispheric dominance, while holding their infants, suggesting that increase of OT level might activate paternal PFC related to parenting behavior, although the same is not true for mothers.

    Psychopathy is a group of personality traits that are associated with violations of social norms. Previous studies have suggested that people with psychopathic traits in subclinical populations do not necessarily display antisocial, self-defeating behaviors, and instead may strategically show adaptive behaviors in response to cues during reciprocal social interactions. Therefore, in the present study, we examined whether the association between psychopathic traits and unfair behavior can be moderated by a potential for punishment and social distance (anonymity), which are known to facilitate fair behavior. We focused on two psychopathic traits: primary and secondary psychopathy. Primary psychopathy is characterized by callousness, shallow affect, manipulation, and superficial charm. In contrast, secondary psychopathy is associated with impulsivity and lack of long-term goals, and is related to hostile behavior. A total of 348 undergraduate students determined the amounts of money that they would offer to strangers or friends at their university in hypothetical scenarios of the ultimatum game (UG) and the dictator game (DG). While gender affected decisions in the hypothetical scenarios of the DG, it did not interact with psychopathic traits. The score for primary psychopathy on the Levenson self-report psychopathy scale predicted unfair monetary offers to strangers in the DG, where participants could not be punished. However, compared with their offers in the DG, individuals with higher scores for primary psychopathy made larger offers in the UG, where low offers could trigger punishment from the recipient. Moreover, primary psychopathy did not decrease the amounts of offers in either game when the participant considered the recipient to be a friend. On the other hand, secondary psychopathy was not associated with differences in behavioral fairness depending on a potential for punishment or social distance. Based on these findings, we discuss strategic social skills as a function of primary psychopathy.

    A broadly used computational framework posits that two learning systems operate in parallel during the learning of choice preferences—namely, the model-free and model-based reinforcement-learning systems. In this study, we examined another possibility, through which model-free learning is the basic system and model-based information is its modulator. Accordingly, we proposed several modified versions of a temporal-difference learning model to explain the choice-learning process. Using the two-stage decision task developed by Daw, Gershman, Seymour, Dayan, and Dolan (2011), we compared their original computational model, which assumes a parallel learning process, and our proposed models, which assume a sequential learning process. Choice data from 23 participants showed a better fit with the proposed models. More specifically, the proposed eligibility adjustment model, which assumes that the environmental model can weight the degree of the eligibility trace, can explain choices better under both model-free and model-based controls and has a simpler computational algorithm than the original model. In addition, the forgetting learning model and its variation, which assume changes in the values of unchosen actions, substantially improved the fits to the data. Overall, we show that a hybrid computational model best fits the data. The parameters used in this model succeed in capturing individual tendencies with respect to both model use in learning and exploration behavior. This computational model provides novel insights into learning with interacting model-free and model-based components.

    It is well known that the insular cortex (Brodmann areas 13,14, 15, and 16) located deep inside the Sylvian fissure is associated with mental functions such as perception, language, cognition, affect, and movement. In particular, the insular cortex has been linked to interoception, which is the representation of bodily physiological states that is used to regulate bodily states and mental functions. Recently, a common principle to explain such functions of the insular cortex has been proposed. The principle posits that the anterior insula generates predictions of future bodily states, computes the error by comparing the prediction with the actual sensory signals, and integrates the body with the mind by minimizing the prediction error. This article describes the functions of the insular cortex, and discusses the possibility that an error-minimizing function can affect decision-making to regulate behaviors.

    Previous studies have reported that the concealed information test (CIT) is a reliable and powerful method for detecting information. However, the external validity of the CIT studies has not been fully proven. In particular, few studies have examined the effects of emotional arousal at memory encoding on physiological responses in the CIT. The present study investigated the influence on the CIT of the magnitude of emotional arousal at memory encoding of a mock crime, using the P300 component of the event-related brain potential (ERP). In accord with the assumptions of excitation-transfer theory, we presented emotionally arousing pictures before a mock crime. Participants were randomly assigned to either a high emotional arousal group (n = 10) or a low emotional arousal group (n = 11), viewing pictures expected to arouse emotion at a high or low level, respectively. Subsequently, all participants enacted the same mock crime, in which they were instructed to stab a pillow with a sharp-edged tool (e.g., a kitchen knife or ice pick) as if harassing a mannequin lying on a bed. After the antecedent emotional experience, the P300-based CIT was conducted. Participants in the high arousal group showed significantly greater P300 amplitudes in response to a probe stimulus compared with the low arousal group. No differences were found between the groups in response to irrelevant stimuli. These results support the notion that emotional arousal influences the P300 in the CIT paradigm.

    Happiness is regarded as one of the most fundamental human goals. Given recent reports that positive feelings are contagious (e.g., the presence of a happy person enhances others' happiness) because of the human ability to empathize (i.e., sharing emotions), empathic ability may be a key factor in increasing one's own subjective level of happiness. Based on previous studies indicating that a single nucleotide polymorphism in the serotonin 2A receptor gene [HTR2A rs6311 guanine (G) vs. adenine (A)] is associated with sensitivity to emotional stimuli and several mental disorders such as depression, we predicted that the polymorphism might be associated with the effect of sharing happiness. To elucidate the neural and genetic correlates of the effect of sharing happiness, we first performed functional magnetic resonance imaging (fMRI) during a "happy feelings" evocation task (emotional event imagination task), during which we manipulated the valence of the imagined event (positive, neutral, or negative), as well as the presence of a friend experiencing a positive-valence event (presence or absence). We recruited young adult women for this fMRI study because empathic ability may be higher in women than in men. Participants felt happier (p < 0.01) and the mentalizing/theory-of-mind network, which spans the medial prefrontal cortex, temporoparietal junction, temporal poles, and precuneus, was significantly more active (p < 0.05) in the presence condition than in the absence condition regardless of event valence. Moreover, participants with the GG (p < 0.01) and AG (p < 0.05) genotypes of HTR2A experienced happier feelings as well as greater activation of a part of the mentalizing/theory-of-mind network (p < 0.05) during empathy for happiness (neutral/presence condition) than those with the AA genotype. In a follow-up study with a vignette-based questionnaire conducted in a relatively large sample, male and female participants were presented with the same imagined events wherein their valence and the presence of a friend were manipulated. Results showed genetic differences in happiness-related empathy regardless of sex (p < 0.05). Findings suggest that HTR2A polymorphisms are associated with the effect of sharing happiness by modulating the activity of the mentalizing/theory-of-mind network.

  88. Heart-rate deceleration predicting the determination of costly punishment: Implications for its involvement in cognitive effort expended in overriding self-interest 査読有り

    Previous studies have investigated which biological markers predict the decision to reject unfair monetary offers, termed costly punishment, in the ultimatum game (UG). One study showed that a phasic deceleratory response in heart rate (HR) is evoked in the responder more readily by offers that will be rejected than by offers that will be accepted. However, owing to the paucity of supporting evidence, it remains unclear whether and why HR deceleration can predict the decisions of UG responders. In this paper, we report two separate studies (Study 1 and Study 2) using modified versions of the UG to explore factors modulating HR deceleration. In Study 1, as well as unfair offers, fair offers induced greater HR deceleration when responders were forced to reject offers compared to when they were forced to accept offers. In Study 2, a high rejection rate for very unfair offers was sustained, regardless of the size of the offers, but HR deceleration was increased for unfair but large offers, relative to unfair, small offers. Moreover, HR deceleration was associated with the rejection of large offers. However, across the two studies, HR deceleration did not simply vary depending on unfairness. These findings support the possibility that HR decelerates as a function of cognitive load in determining costly punishment.

  89. Self-Other Distinction Enhanced Empathic Responses in Individuals with Alexithymia 査読有り

    Although empathy is important for social interactions, individuals with alexithymia have low empathic ability, particularly where advanced empathy is concerned (empathic concern, perspective taking). It has been argued that awareness of the self-other distinction enhances advanced empathy, and alexithymics are thought to inadequately distinguish the self from others. We therefore tested whether the self-other distinction increases advanced empathy in alexithymics. To this end, we presented painful hand images over participants' own hands, and required participants to estimate felt pain intensity and their affective states. Half of the participants got specific instructions to distinct themselves from the other in the images. Felt pain intensity (perspective taking) and other-oriented affective responses (empathic concern) were increased by the instructions only when participants had high alexithymia scores as measured by questionnaire, although self-oriented affective responses (personal distress) were not affected by the instructions. These findings indicate that enhancing the self-other distinction enhances alexithymics' ability to use advanced empathy, but not the primitive empathy.

    This study investigates the prolonged effects of physiological responses induced by acute stress on risk-taking in decision-making. Participants were divided into a Stress group (N = 14) and a Control group (N = 12). The Trier Social Stress Test was administered as an acute stressor, and reading was administered as a control task; thereafter, participants performed a decision-making task in which they needed to choose a sure option or a gamble option in Gain and Loss frame trials 2 h after (non-) exposure to the stressor. Increased cortisol, adrenaline, heart rate (HR), and subjective stress levels validated acute stress manipulation. Stressed participants made fewer risky choices only in the Gain domain, whereas no effect of stress was shown in the Loss domain. Deceleration of HR reflecting attention was greater for Gains compared with Losses only in the Stress group. Risk avoidance was determined by increased levels of cortisol caused by acute stress. These results suggest that processes regarding glucocorticoid might be involved in the prolonged effects of acute stress on the evaluation of risks and the monitoring of outcomes in decision-making.

    Background Three-year clinical follow-up of patients with diabetes mellitus (DM) in the Japan-Drug Eluting Stents Evaluation; a Randomized Trial (J-DESsERT) using 2 different drug eluting stents (DES). A recent study demonstrated that efficacy of sirolimus eluting stents (SES) attenuated over time in diabetic patients. Methods In the largest trial of its kind, 1724 DM patients out of 3533 enrolled patients were randomized to either SES or paclitaxel eluting stents (PES). Results There were no significant differences in baseline clinical characteristics aside from hypertension. Incidence of major adverse cardiac cerebrovascular events (MACCE) mainly due to higher target vessel failure (TVF) initially indicated a benefit in SES (MACCE rate at 1 year: SES 9.4%, PES 12.2%, p = 0.08); however this had attenuated by the time of the 3-year follow-up (MACCE rate from 1 to 3 years: SES 8.4%, PES 6.1%, p = 0.10). A similar pattern was observed in insulin-treated patients: MACCE rate from 1 to 3 years was 10.5% in SES and 6.4% in PES (p = 0.25). Angiographic follow-up also resulted in higher major adverse cardiac event (MACE) rates at 1 year (presence 11.5%, absence 8.3%, p = 0.04); however by 3 years rates were similar regardless of the presence of angiographic follow-up (MACE rate at 3 years: presence 16.0%, absence 14.5%, p = 0.35). Conclusions The superiority of SES over PES in MACCE at 1 year had attenuated by 3-year follow-up. Eventually, the 3-year safety and efficacy profiles were similar regardless of insulin treatment.

  100. Involvement of the ventrolateral prefrontal cortex in learning others’ bad reputations and indelible distrust

    A bad reputation can persistently affect judgments of an individual even when it turns out to be invalid and ought to be disregarded. Such indelible distrust may reflect that the negative evaluation elicited by a bad reputation transfers to a person. Consequently, the person him/herself may come to activate this negative evaluation irrespective of the accuracy of the reputation. If this theoretical model is correct, an evaluation-related brain region will be activated when witnessing a person whose bad reputation one has learned about, regardless of whether the reputation is deemed valid or not. Here, we tested this neural hypothesis with functional magnetic resonance imaging (fMRI). Participants memorized faces paired with either a good or a bad reputation. Next, they viewed the faces alone and inferred whether each person was likely to cooperate, first while retrieving the reputations, and then while trying to disregard them as false. A region of the left ventrolateral prefrontal cortex (vlPFC), which may be involved in negative evaluation, was activated by faces previously paired with bad reputations, irrespective of whether participants attempted to retrieve or disregard these reputations. Furthermore, participants showing greater activity of the left ventrolateral prefrontal region in response to the faces with bad reputations were more likely to infer that these individuals would not cooperate. Thus, once associated with a bad reputation, a person may elicit evaluation-related brain responses on their own, thereby evoking distrust independently of their reputation.

A major genetic factor determining inter-individual differences in stress reactivity is polymorphisms of the serotonin (5-hydroxytryptamine, 5HT) transporter (5HTT) gene. A short (S) variant, compared with a long (L) variant, of the promoter region of the 5HTT gene-linked polymorphic region (5HTTLPR) has been related to emotional and stress hyper-reactivity. The present study examined whether the 5HTTLPR can modulate responses of inflammatory cytokines under acute stress. Nine Japanese male participants carrying two copies of the S alleles and nine Japanese males carrying S and L alleles underwent the Trier Social Stress Test (TSST). Inflammatory cytokines, endocrine parameters, heart rate and subjective stress were measured before, during and after the task. The participants carrying the SS alleles, but not those carrying the SL alleles, showed a significant increase of IL-1β immediately after TSST. This hyper-reactivity to acute stress in individuals with the SS alleles was also observed in their heart rate and cortisol levels. These results suggest that the S allele of the 5HTTLPR is consistently associated with stress reactivity in multi-level stress-related biological systems.

    Patients suffering from neuropsychiatric disorders such as substance-related and addictive disorders exhibit altered decision-making patterns, which may be associated with their behavioral abnormalities. However, the neuronal mechanisms underlying such impairments are largely unknown. Using a gambling test, we demonstrated that methamphetamine (METH)-treated rats chose a high-risk/high-reward option more frequently and assigned higher value to high returns than control rats, suggestive of changes in decision-making choice strategy. Immunohistochemical analysis following the gambling test revealed aberrant activation of the insular cortex (INS) and nucleus accumbens in METH-treated animals. Pharmacological studies, together with in vivo microdialysis, showed that the insular neural system played a crucial role in decision-making. Moreover, manipulation of INS activation using designer receptor exclusively activated by designer drug technology resulted in alterations to decision-making. Our findings suggest that the INS is a critical region involved in decision-making and that insular neural dysfunction results in risk-taking behaviors associated with altered decision-making.

    Background: The association between diabetes mellitus (DM) and low secretory immunoglobulin A (s-IgA) secretion rates is one mechanism suspected of influencing susceptibility to infections among DM patients. However, several studies have shown contradictory results. We examined these two factors to seek evidence of an association among older people. Methods: We analyzed a prospective cohort of 2306 subjects (1209 men and 1097 women) around 64 years old from the New Integrated Suburban Seniority Investigation (NISSIN) Project in Nisshin, Japan. DM statuses were ascertained from levels of fasting plasma glucose and HbA1c, and s-IgA secretion rates were obtained from 5-min saliva samples. We used an analysis of covariance adjusted for possible confounders to compare s-IgA secretion rates according to DM status. Results: s-IgA secretion rates in DM participants were lower than in those classified as normal (18.6 mu g/min vs 15.0 mu g/min, P = 0.03), even after elimination of the effects of possible confounders. Conclusions: DM was associated with lower s-IgA secretion rates. This suggests that lower s-IgA levels may be a mechanism of susceptibility to infection in individuals with DM.

    Introduction: The letters F, A and S, originally used in the English letter fluency stimuli test, have been frequently adopted to assess executive function in many languages. However, few studies reported the significance of FAS testing employed in different languages. The current study explored whether FAS could be widely applied to the Indonesian language. Methods: A total of 211 undergraduate students from state and private universities who participated in this study were randomly assigned into four groups. Each group was exposed to six different letter fluency stimuli. The total number of words the participants produced for each letter stimulus were averaged and ranked to determine the degree of difficulty in generating words. Furthermore, the normal distribution and equal ratio comparison were examined to verify the representative letter fluency stimuli. In addition, the effect of sex and university affiliation on letter fluency performance was also analyzed. Results: The letters A and S were among the easiest letters used to generate words; however, the letter F was regarded as a difficult stimulus. Furthermore, only the number of words beginning the letter S was distributed according to a normal curve. The number of words starting with the letters F and A were not normally distributed. Although sex difference was not associated with letter fluency performance, difference in university affiliation showed a significant effect on performance. Discussion: Our findings suggest that consideration of several stimuli factors is required to accurately measure performance in the letter fluency task in a specific language.

    We sometimes make decisions relying not necessarily on deliberative thoughts but on intuitive and emotional processes in uncertain situations. The somatic marker hypothesis proposed by Damasio argued that interoception, which means bodily responses such as sympathetic activity, can be represented in the insula and anterior cingulate cortex and can play critical roles in decision-making. Though this hypothesis has been criticized in its theoretical and empirical aspects, recent studies are expanding the hypothesis to elucidate multiple bodily responses including autonomic, endocrine, and immune activities that affect decision-making. In addition, cumulative findings suggest that the anterior insula where the inner model of interoception is represented can act as an interface between the brain and body in decision-making. This article aims to survey recent findings on the brain-body interplays underlying decision-making, and to propose hypotheses on the significance of the body in decision-making.

    Feedback-related negativity (FRN) is an event-related brain potential (ERP) component elicited by errors and negative outcomes. Previous studies proposed that FRN reflects the activity of a general error-processing system that incorporates reward prediction error (RPE). However, other studies reported inconsistent results on this issue - namely, that FRN only reflects the valence of feedback and that the magnitude of RPE is reflected by the other ERP component called P300. The present study focused on the relationship between the FRN amplitude and RPE. ERPs were recorded during a reversal learning task performed by the participants, and a computational model was used to estimate trial-by-trial RPEs, which we correlated with the ERPs. The results indicated that FRN and P300 reflected the magnitude of RPE in negative outcomes and positive outcomes, respectively. In addition, the correlation between RPE and the P300 amplitude was stronger than the correlation between RPE and the FRN amplitude. These differences in the correlation between ERP and RPE components may explain the inconsistent results reported by previous studies; the asymmetry in the correlations might make it difficult to detect the effect of the RPE magnitude on the FRN and makes it appear that the FRN only reflects the valence of feedback.

    We analyzed skin conductance response (SCR) as a psychophysiological index to evaluate affective aspects of consumer preferences for cosmetic products. To examine the test-retest reliability of association between preferences and SCR, we asked 33 female volunteers to complete two experimental sessions approximately 1 year apart. The participants indicated their preferences in a typical paired comparison task by choosing the better option from a combination of two products among four products. We measured anticipatory SCR prior to expressions of the preferences. We found that the mean amplitude of the SCR elicited by the preferred products was significantly larger than that elicited by the non-preferred products. The participants' preferences and corresponding SCR patterns were well preserved at the second session 1 year later. Our results supported cumulating findings that SCR is a useful index of consumer preferences that has future potential, both in laboratory and marketing settings.

    Click beetles (Coleoptera: Elateridae) represent one of the largest groups of beetle insects. Some click beetles in larval form, known as wireworms, are destructive agricultural pests. Morphological identification of click beetles is generally difficult and requires taxonomic expertise. This study reports on the DNA barcoding of Japanese click beetles to enable their rapid and accurate identification. We collected and assembled 762 cytochrome oxidase subunit I barcode sequences from 275 species, which cover approximately 75% of the common species found on the Japanese main island, Honshu. This barcode library also contains 20 out of the 21 potential pest species recorded in Japan. Our analysis shows that most morphologically identified species form distinct phylogenetic clusters separated from each other by large molecular distances. This supports the general usefulness of the DNA barcoding approach for quick and reliable identification of Japanese elaterid species for environmental impact assessment, agricultural pest control, and biodiversity analysis. On the other hand, the taxonomic boundary in dozens of species did not agree with the boundary of barcode index numbers (a criterion for sequence-based species delimitation). These findings urge taxonomic reinvestigation of these mismatched taxa.

    Purpose: The right ventricle (RV) has a high capacity to adapt to pressure or volume overload before failing. However, the mechanisms of RV adaptation, in particular RV energetics, in patients with pulmonary hypertension (PH) are still not well understood. We aimed to evaluate RV energetics including RV oxidative metabolism, power and efficiency to adapt to increasing pressure overload in patients with PH using 11C-acetate PET. Methods: In this prospective study, 27 patients with WHO functional class II/III PH (mean pulmonary arterial pressure 39.8±13.5 mmHg) and 9 healthy individuals underwent 11C-acetate PET. 11C-acetate PET was used to simultaneously measure oxidative metabolism (k mono) for the left ventricle (LV) and RV. LV and RV efficiency were also calculated. Results: The RV ejection fraction in PH patients was lower than in controls (p=0.0054). There was no statistically significant difference in LV k mono (p=0.09). In contrast, PH patients showed higher RV k mono than did controls (0.050±0.009 min-1 vs. 0.030±0.006 min-1, p<0.0001). PH patients exhibited significantly increased RV power (p<0.001) and hence increased RV efficiency compared to controls (0.40±0.14 vs. 0.017±0.12 mmHg·mL·min/g, p=0.001). Conclusion: The RV oxidative metabolic rate was increased in patients with PH. Patients with WHO functional class II/III PH also had increased RV power and efficiency. These findings may indicate a myocardial energetics adaptation response to increasing pulmonary arterial pressure. © 2014 Springer-Verlag Berlin Heidelberg.

    Humans are capable of correcting their actions based on actions performed in the past, and this ability enables them to adapt to a changing environment. The computational field of reinforcement learning (RL) has provided a powerful explanation for understanding such processes. Recently, the dual learning system, modeled as a hybrid model that incorporates value update based on reward-prediction error and learning rate modulation based on the surprise signal, has gained attention as a model for explaining various neural signals. However, the functional significance of the hybrid model has not been established. In the present study, we used computer simulation in a reversal learning task to address functional significance in a probabilistic reversal learning task. The hybrid model was found to perform better than the standard RL model in a large parameter setting. These results suggest that the hybrid model is more robust against the mistuning of parameters compared with the standard RL model when decision-makers continue to learn stimulus-reward contingencies, which can create abrupt changes. The parameter fitting results also indicated that the hybrid model fit better than the standard RL model for more than 50% of the participants, which suggests that the hybrid model has more explanatory power for the behavioral data than the standard RL model. © 2014 Bai, Katahira and Ohira.

    We previously reported that sympathetic activity was associated with exploration in decision-making indexed by entropy, which is a concept in information theory and indexes randomness of choices or the degree of deviation from sticking to recent experiences of gains and losses, and that activation of the anterior insula mediated this association. The current study aims to replicate and to expand these findings in a situation where contingency between options and outcomes is manipulated. Sixteen participants performed a stochastic decision-making task in which we manipulated a condition with low uncertainty of gain/loss (contingent-reward condition) and a condition with high uncertainty of gain/loss (random-reward condition). Regional cerebral blood flow was measured by 15O-water positron emission tomography (PET), and cardiovascular parameters and catecholamine in the peripheral blood were measured, during the task. In the contingent-reward condition, norepinephrine as an index of sympathetic activity was positively correlated with entropy indicating exploration in decision-making. Norepinephrine was negatively correlated with neural activity in the right posterior insula, rostral anterior cingulate cortex, and dorsal pons, suggesting neural bases for detecting changes of bodily states. Furthermore, right anterior insular activity was negatively correlated with entropy, suggesting influences on exploration in decision-making. By contrast, in the random-reward condition, entropy correlated with activity in the dorsolateral prefrontal and parietal cortices but not with sympathetic activity. These findings suggest that influences of sympathetic activity on exploration in decision-making and its underlying neural mechanisms might be dependent on the degree of uncertainty of situations.

    Happiness has been viewed as a temporary emotional state (e.g., pleasure) and a relatively stable state of being happy (subjective happiness level). As previous studies demonstrated that individuals with high subjective happiness level rated their current affective states more positively when they experience positive events, these two aspects of happiness are interrelated. According to a recent neuroimaging study, the cytosine to thymine single-nucleotide polymorphism of the human cannabinoid receptor 1 gene is associated with sensitivity to positive emotional stimuli. Thus, we hypothesized that our genetic traits, such as the human cannabinoid receptor 1 genotypes, are closely related to the two aspects of happiness. In Experiment 1, 198 healthy volunteers were used to compare the subjective happiness level between cytosine allele carriers and thymine-thymine carriers of the human cannabinoid receptor 1 gene. In Experiment 2, we used positron emission tomography with 20 healthy participants to compare the brain responses to positive emotional stimuli of cytosine allele carriers to that of thymine-thymine carriers. Compared to thymine-thymine carriers, cytosine allele carriers have a higher subjective happiness level. Regression analysis indicated that the cytosine allele is significantly associated with subjective happiness level. The positive mood after watching a positive film was significantly higher for the cytosine allele carriers compared to the thymine-thymine carriers. Positive emotion-related brain region such as the medial prefrontal cortex was significantly activated when the cytosine allele carriers watched the positive film compared to the thyminethymine carriers. Thus, the human cannabinoid receptor 1 genotypes are closely related to two aspects of happiness. Compared to thymine-thymine carriers, the cytosine allele carriers of the human cannabinoid receptor 1 gene, who are sensitive to positive emotional stimuli, exhibited greater magnitude positive emotions when they experienced positive events and had a higher subjective happiness level. © 2014 Matsunaga et al.

    When distinguishing whether a face displays a certain emotion, some regions of the face may contain more useful information than others. Here we ask whether people differentially attend to distinct regions of a face when judging different emotions. Experiment 1 measured eye movements while participants discriminated between emotional (joy, anger, fear, sadness, shame, and disgust) and neutral facial expressions. Participant eye movements primarily fell in five distinct regions (eyes, upper nose, lower nose, upper lip, nasion). Distinct fixation patterns emerged for each emotion, such as a focus on the lips for joyful faces and a focus on the eyes for sad faces. These patterns were strongest for emotional faces but were still present when viewers sought evidence of emotion within neutral faces, indicating a goal-driven influence on eye-gaze patterns. Experiment 2 verified that these fixation patterns tended to reflect attention to the most diagnostic regions of the face for each emotion. Eye movements appear to follow both stimulus-driven and goal-driven perceptual strategies when decoding emotional information from a face.

    While emotions themselves are beneficial for our survival, they are also the targets to be regulated appropriately to adapt to social environments. Previous studies have demonstrated that cognitive strategies such as cognitive reappraisal and expressive suppression can effectively enhance and attenuate emotions. Such cognitive strategies of emotion regulation are based on cortical modulation of sub-cortical emotion-related brain regions. Though in the prior studies emotion regulation was conducted in parallel with or after the emotion elicitation, a series of our studies showed that prior cognitive activities can automatically and unintentionally attenuate subsequent emotional responses. In this article, after reviewing the previous findings about emotion regulation, we introduce our empirical findings showing that cognitive activities where the neural system of emotion regulation would be recruited can unintentionally and automatically dampen psychological and physiological emotional responses. Finally, we propose possible neural mechanisms underlying modulation of emotion by cognitive activity.

    The somatic marker hypothesis asserts that decision-making can be guided by feedback of bodily states to the brain. In line with this hypothesis, the present study tested whether sympathetic activity shows an association with a tonic dimension of decision-making, exploratory tendency represented by entropy in information theory, and further examined the neural mechanisms of the association. Twenty participants performed a stochastic reversal learning task that required decision-making in an unstable and uncertain situation. Regional cerebral blood flow was evaluated using 15O-water positron emission tomography (PET), and cardiovascular indices and concentrations of catecholamine in peripheral blood were also measured, during the task. In reversal learning, increased epinephrine during the task positively correlated with larger entropy, indicating a greater tendency for exploration in decision-making. The increase of epinephrine also correlated with brain activity revealed by PET in the somatosensory cortices, anterior insula, dorsal anterior cingulate cortex, and the dorsal pons. This result is consistent with previously reported brain matrixes of representation of bodily states and interoception. In addition, activity of the anterior insula specifically correlated with entropy, suggesting possible mediation of this brain region between peripheral sympathetic arousal and exploration in decision-making. These findings shed a new light about a role of bodily states in decision-making and underlying neural mechanisms. © 2013 IBRO.

    The phenomenon in which a certain smell evokes a specific memory is known as the Proust phenomenon. Odor-evoked autobiographic memories are more emotional than those elicited by other sensory stimuli. The results of our previous study indicated that odor-evoked autobiographic memory accompanied by positive emotions has remarkable effects on various psychological and physiological activities, including the secretion of cytokines, which are immune-signaling molecules that modulate systemic inflammation. In this study, we aimed to clarify the neural substrates associated with the interaction between odor-evoked autobiographic memory and peripheral circulating cytokines. We recruited healthy male and female volunteers and investigated the association between brain responses and the concentration of several cytokines in the plasma by using positron emission tomography (PET) recordings when an autographic memory was evoked in participants by asking them to smell an odor that was nostalgic to them. Participants experienced positive emotions and autobiographic memories when nostalgic odors were presented to them. The levels of peripheral proinflammatory cytokines, such as the tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ), were significantly reduced after experiencing odor-evoked autobiographic memory. Subtraction analysis of PET images indicated that the medial orbitofrontal cortex (mOFC) and precuneus/posterior cingulate cortex (PCC) were significantly activated during experiences of odor-evoked autobiographic memory. Furthermore, a correlation analysis indicated that activities of the mOFC and precuneus/PCC were negatively correlated with IFN-γ concentration. These results indicate that the neural networks including the precuneus/PCC and mOFC might regulate the secretion of peripheral proinflammatory cytokines during the experience of odor-evoked autobiographic memories accompanied with positive emotions. © 2013 Matsunaga et al.

    We investigated whether vagal tone, as assessed by heart rate variability (HRV), moderates the neural correlates of immune and physiological responses to acute stress. Participants with low and high baseline HRV underwent a reversal learning task as an acute stressor. Natural killer cells, norepinephrine, and adrenocorticotropic hormone in peripheral blood changed with acute stress in the high HRV group only. Activity in the prefrontal cortex and striatum correlated with the immune and physiological indices in the high HRV group. High vagal tone may reflect more flexible top-down brain regulation of immune and physiological activity. (C) 2013 Elsevier B.V. All rights reserved.

    Aim: The number of patients with autoimmune hepatitis (AIH) showing acute presentation has increased. This study aimed to assess their prognosis. Methods: A survey of AIH patients by sending questionnaires was performed, and 96 patients showing acute presentation were investigated. Results: The median age was 58 years and 78 patients (81%) were female. Eighty-four patients (88%) were positive for antinuclear antibody and/or anti-smooth muscle antibody. The median serum immunoglobulin G level was 2252mg/dL. Twenty-five patients (26%) showed histological acute hepatitis. As initial treatment, 88 patients (92%) were treated with corticosteroid, and 28 of them received pulse steroid treatment. Overall, 11 patients (11%) reached fatal outcomes (nine death and two liver transplantation). Patients with histological acute hepatitis showed higher serum bilirubin levels, lower prothrombin activities and higher prothrombin time-international normalized ratios (PT-INR) and reached fatal outcomes more frequently. With a multivariate logistic regression analysis, prothrombin activity and PT-INR at presentation was associated with fatal outcomes. Nine of 13 patients (69%) showing prothrombin activity of 40% or lower at presentation and nine of 19 patients (47%) showing PT-INR of 1.5 or higher reached fatal outcomes. Furthermore, of 13 patients showing prothrombin activity of 40% or lower and/or PT-INR of 1.5 or higher at presentation who were treated with pulse steroid treatment, four (31%) died from infectious disease. Conclusion: Prothrombin activity and PT-INR are prognostic factors for AIH showing acute presentation. Physicians should pay attention to the development of infectious disease when pulse steroid treatment is performed. © 2012 The Japan Society of Hepatology.

    The present study was performed to investigate the associations between eye-blink behaviors and various other factors in primates. We video-recorded 141 individuals across 71 primate species and analyzed the blink rate, blink duration, and "isolated" blink ratio (i.e., blinks without eye or head movement) in relation to activity rhythms, habitat types, group size, and body size factors. The results showed close relationships between three types of eye-blink measures and body size factors. All of these measures increased as a function of body weight. In addition, diurnal primates showed more blinks than nocturnal species even after controlling for body size factors. The most important findings were the relationships between eye-blink behaviors and social factors, e.g., group size. Among diurnal primates, only the blink rate was significantly correlated even after controlling for body size factors. The blink rate increased as the group size increased. Enlargement of the neocortex is strongly correlated with group size in primate species and considered strong evidence for the social brain hypothesis. Our results suggest that spontaneous eye-blinks have acquired a role in social communication, similar to grooming, to adapt to complex social living during primate evolution. © 2013 Tada et al.

    OBJECTIVES: This study aimed to examine one of biological correlates, proinflammatory cytokine, in rejection of unfair financial offers in the Ultimatum Game (UG), where the division of a sum of money is proposed and the player can accept or reject this offer. METHODS: Nineteen participants played 20 trials of the UG as responders, and they were proposed unfair offers in a half of the trials. Baseline levels of several pro-inflammatory and anti-inflammatory cytokines, subjective happiness, and depression of them were measured. RESULTS: Participants with higher levels of the pro-inflammatory cytokine, interleukin (IL)-6 rejected fewer unfair offers. This effect of IL-6 levels on decision-making was independent from other pro-inflammatory cytokines, anti-inflammatory cytokines, subjective happiness, and depression. CONCLUSIONS: These results suggested that chronic higher levels of IL-6 might affect functions of neural regions related to decision making, and thus can modulate rejection of unfair offers. © 2013 Neuroendocrinology Letters.

    Background: Individuals with psychopathy have an increased tendency toward certain types of aggression. We hypothesized that successful psychopaths, who have no criminal convictions but can be diagnosed with psychopathy in terms of personality characteristics, are skilled at regulating aggressive impulses, compared to incarcerated unsuccessful psychopaths. Methods: In this block-designed functional magnetic resonance imaging (fMRI) study, we sought to clarify the neural mechanisms underlying differences in frustration-induced aggression as a function of psychopathy in non-criminal populations. Twenty male undergraduate students who completed a self-report psychopathy questionnaire were scanned while they completed a task in which they either could or could not punish other individuals who made unfair offers of monetary distribution. Results: Individuals with high psychopathic tendencies were less likely to make a decision to inflict costly punishment on people proposing unfair offers. During this decision-making, psychopathy was associated with less amygdala activity in response to the unfairness of offers. Moreover, the amygdala dysfunction in psychopathic individuals was associated with reduced functional connectivity with dopaminergic-related areas, including the striatum, when punishment was available compared to when it was unavailable. Limitations: The possibility that levels of psychopathic traits in a regular population were milder than in incarcerated populations cannot be ruled out. Conclusions: The findings indicate that amygdala dysfunction underlies affective deficits of psychopathy. We propose that the insensitivity of the amygdala to the affective significance of social stimuli contributes to an increased risk of violation of social norms, but enhances the ability to attenuate impulses toward maladaptive aggression in successful psychopaths. © 2012 Elsevier B.V.

    Mindfulness is currently attracting a great deal of attention as a psychotherapy technique. It is defined as bringing one's complete attention to the experiences occurring in the present moment in a nonjudgmental or accepting way. The Five Facet Mindfulness Questionnaire (FFMQ) was developed to assess individual differences in mindfulness states. The FFMQ is composed of five facets representing elements of mindfulness: non-reactivity to inner experience, non-judging, acting with awareness, describing, and observing. In the present study, we applied voxel-based morphometry to investigate the relationship between the brain structure and each facet as measured by the FFMQ. The results showed a positive association between the describing facet of mindfulness on the FFMQ and gray matter volume in the right anterior insula and the right amygdala. In conclusion, mindfulness was related with development in parts of the somatic marker circuit of the brain. © 2012 Murakami et al.

    The ability to extract sequential regularities embedded in the temporal context or temporal structure of sensory events and to predict upcoming events based on the extracted sequential regularities plays a central role in human cognition. In the present study, we demonstrate that, without any intention, upcoming emotional faces can be predicted based on sequential regularities, by showing that prediction error responses as reflected by visual mismatch negativity (MMN), an event-related brain potential (ERP) component, were evoked in response to emotional faces that violated a regular alternation pattern of 2 emotional faces (fearful and happy faces) under a situation where the emotional faces themselves were unrelated to the participant's task. Face-inversion and negative-bias effects in the visual MMN further indicated the involvement of holistic face representations. In addition, through successive source analyses of the visual MMN, it was revealed that the prediction error responses were composed of activations mainly in the face-responsible visual extrastriate areas and the prefrontal areas. The present results provide primary evidence for the existence of the unintentional temporal context-based prediction of biologically relevant visual stimuli as well as empirical support for the major engagement of the visual and prefrontal areas in unintentional temporal context-based prediction in vision. © 2011 The Author.

    It has been reported that engagement in several kinds of cognitive activity can successfully inhibit unpleasant emotions. In this study, we tried to replicate the previous finding that cognitive activity can modulate subsequent psychological and physiological emotional processes and to investigate whether prior cognitive activity can attenuate implicit emotional processes triggered by subliminal emotional stimuli. Sixty students were randomly divided into three groups (cognitive task group, noncognitive task group, control group). The cognitive task group was asked to engage in an n-back task, while the control group was asked to stay calm. The noncognitive task group was asked to do a handgrip-squeezing task. All participants then engaged in a version of a subliminal affective priming task where they were unconsciously exposed to affectively negative pictures. The cognitive task group showed lower negative experiences after the subliminal affective priming task and a substantial reduction in their heart rate responses, as compared with the other groups. These results provide evidence that engagement in cognitive activity can attenuate emotional processes in an automatic and unconscious manner. © Psychonomic Society, Inc. 2012.

    Individual differences in baseline executive functioning (EF) capacities have been shown to predict state anxiety during acute stressor exposure. However, no previous studies have clearly demonstrated the relationship between EF and physiological measures of stress. The present study investigated the efficacy of several well-known EF tests (letter fluency, Stroop test, and Wisconsin Card Sorting Test) in predicting both subjective and physiological stress reactivity during acute psychosocial stress exposure. Our results show that letter fluency served as the best predictor for both types of reactivity. Specifically, the higher the letter fluency score, the lower the acute stress reactivity after controlling for the baseline stress response, as indicated by lower levels of state anxiety, negative mood, salivary cortisol, and skin conductance. Moreover, the predictive power of the letter fluency test remained significant for state anxiety and cortisol indices even after further adjustments for covariates by adding the body mass index (BMI) as a covariate. Thus, good EF performance, as reflected by high letter fluency scores, may dampen acute stress responses, which suggests that EF processes are directly associated with aspects of stress regulation. © 2012 Elsevier B.V.

    Multisensory integration involves bottom-up as well as top-down processes. We investigated the influences of top-down control on the neural responses to multisensory stimulation using EEG recording and time-frequency analyses. Participants were stimulated at the index or thumb of the left hand, using tactile vibrators mounted on a foam cube. Simultaneously they received a visual distractor from a light emitting diode adjacent to the active vibrator (spatially congruent trial) or adjacent to the inactive vibrator (spatially incongruent trial). The task was to respond to the elevation of the tactile stimulus (upper or lower), while ignoring the simultaneous visual distractor. To manipulate top-down control on this multisensory stimulation, the proportion of spatially congruent (vs. incongruent) trials was changed across blocks. Our results reveal that the behavioral cost of responding to incongruent than congruent trials (i.e., the crossmodal congruency effect) was modulated by the proportion of congruent trials. Most importantly, the EEG gamma band response and the gamma-theta coupling were also affected by this modulation of top-down control, whereas the late theta band response related to the congruency effect was not. These findings suggest that gamma band response is more than a marker of multisensory binding, being also sensitive to the correspondence between expected and actual multisensory stimulation. By contrast, theta band response was affected by congruency but appears to be largely immune to stimulation expectancy. © 2011 Elsevier Inc.

    Most experimental studies of decision-making have specifically examined situations in which a single less-predictable correct answer exists (externally guided decision-making under uncertainty). Along with such externally guided decision-making, there are instances of decision-making in which no correct answer based on external circumstances is available for the subject (internally guided decision-making). Such decisions are usually made in the context of moral decision-making as well as in preference judgment, where the answer depends on the subject's own, i.e., internal, preferences rather than on external, i.e., circumstantial, criteria. The neuronal and psychological mechanisms that allow guidance of decisions based on more internally oriented criteria in the absence of external ones remain unclear. This study was undertaken to compare decision-making of these two kinds empirically and theoretically. First, we reviewed studies of decision-making to clarify experimental-operational differences between externally guided and internally guided decision-making. Second, using multi-level kernel density analysis, a whole-brain-based quantitative meta-analysis of neuroimaging studies was performed. Our meta-analysis revealed that the neural network used predominantly for internally guided decision-making differs from that for externally guided decision-making under uncertainty. This result suggests that studying only externally guided decision-making under uncertainty is insufficient to account for decision-making processes in the brain. Finally, based on the review and results of the meta-analysis, we discuss the differences and relations between decision-making of these two types in terms of their operational, neuronal, and theoretical characteristics. © 2012 Nakao, Ohira and Northoff.

    The "Proust phenomenon" occurs when a certain smell evokes a specific memory. Recent studies have demonstrated that odor-evoked autobiographic memories are more emotional than those elicited by other sensory stimuli because of the direct neural communication between the olfactory system and the amygdala. The amygdala is known to regulate various physiological activities including the endocrine and immune systems; therefore, odor-evoked autobiographic memory may trigger various psychological and physiological responses; however, the responses elicited by this memory remains obscure. In this study, we aimed to investigate the psychological and physiological responses accompanying odor-evoked autobiographic memory. We recruited healthy male and female volunteers and investigated changes in their mood states and autonomic nervous, endocrine, and immune activities when autobiographic memory was evoked in the participants by asking them to smell an odor(s) that was nostalgic to them. The autobiographic memories associated with positive emotion resulted in increased positive mood states, such as comfort and happiness, and decreased negative mood states, such as anxiety. Furthermore, heart rate was decreased, skin-conductance level was increased, and peripheral interleukin-2 level was decreased after smelling the nostalgic odor. These psychological and physiological responses were significantly correlated. The present study suggests that odor-evoked autobiographic memory along with a positive feeling induce various physiological responses, including the autonomic nervous and immune activities. To the best of our knowledge, the present study is the first to observe an interaction between odor-evoked autobiographic memories and immune function. © 2011 Activitas Nervosa Superior Rediviva.

    The successful regulation of emotion relies heavily on executive function. Until very recently, however, the specific effects of executive function activity on other processes havereceived relatively little empirical attention. The link between executive function and emotional responses suggests that the activation of executive function may play an important role in the attenuation of emotional responses. We conducted twoexperiments to test the hypothesis that decrements in emotional responses following cognitive task performance might be caused, at least in part, by the activation of executive function. First, we sought to test whetherthe activation of executive function reducedemotional responsesimplicitly, without any volitional effort. Next, we sought to examine the link between prior activation of executivefunction and the attenuation of subsequent emotional responses, by comparing the effects of an executive-function-demanding task with the effects of a task that is equally effortful but does not engage executive function. We discuss our results in the context of the role of executive function in the attenuation of emotion. © Psychonomic Society, Inc. 2011.

    Though traditional microeconomics has supposed that human decisions are based on logical and exact computation of cost-benefit balances or efficacies, studies in behavioral economics have shown that humans sometimes make seemingly irrational decisions driven by emotions. In our everyday situations, factors related to decisions are complex and which alternative will be the most beneficial is uncertain. In such cases, emotions have been thought adaptive because they can quickly reduce negative alternatives and facilitate fast and effective decision making. Some theorists argued that one of important sources of such emotional drives affecting decision making is bodily responses that are represented in brain regions (Craig, 2009; Damasio, 1994). In this article, empirical evidence for the functional associations of the brain and body accompanying decision making will be shown as follows. (1) Heart rate responses and concentration of inflammatory cytokine (IL-6) can predict acceptance or rejection of an unfair offer in an economical negotiation game, the Ultimatum Game. Activation of the anterior insula mediates relationship between bodily states and decision making. (2) Sympathetic responses reflected by secretion of adrenaline are represented in brain regions such as the midbrain, anterior cingulate cortex, and anterior insula, and furthermore can determine exploration of decision making in a situation where an action-outcome contingency is stochastic and unstable. These findings suggest beneficial roles of emotion and bodily responses in decision making.

    Animal studies have revealed that chronic stress shifts cognitive strategies from the flexible goal-directed action to the simple and rigid habit action. In addition, stress-induced atrophy in the prefrontal cortex and dorsomedial striatum which are involved in the goal-directed action and hypertrophy of the dorsolateral striatum which is critical for the habit action were parallel with the effects of chronic stress on behaviors. The present study tested whether these previous findings in animal studies are compatible in humans by analyzing effects of chronic stress on neural and cardiovascular responses, which are likely important for performing appropriate actions. Twenty healthy men exposed to low or high chronic job stress performed a stochastic reversal learning task, which required cognitive flexibility and the goal-directed action. Regional cerebral blood flow was evaluated during the task using 15O-water positron emission tomography, and cardiovascular parameters such as blood pressure and heart rate were also measured. During the reversal learning task, whereas participants with low chronic job stress exhibited activity in the anterior caudate, as well as orbitofrontal cortex, ventrolateral prefrontal cortex, insula, and midbrain, which might be related to the goal-directed action, participants with high chronic job stress exhibited no activity in such brain regions. Furthermore, participants with high chronic job stress exhibited less reactivity in diastolic blood pressure, which might be mediated by anterior cingulate cortical activity. These findings, in line with previous studies, suggested that chronic job stress correlates with less activity in brain regions related to the goal-directed action, and insensitive physiological responses in humans. © 2011 IBRO.

However, the neurobiological mechanisms underlying the positive effects of happiness on psychological and physiological wellness remain obscure. In this study, we attempted to clarify the association between systemic inflammation and happiness. METHODS: We recruited 160 healthy volunteers for experiment 1 and compared peripheral inflammatory markers, namely the concentrations of pro-inflammatory cytokines in the serum, between perceived high-happiness and low-happiness groups. Subsequently, we recruited 7 romantic couples for experiment 2 and investigated changes in peripheral pro-inflammatory cytokine levels after the evocation of happiness, which was induced by warm physical contact with the partner. RESULTS: We found that circulating levels of interferon-γ (IFN-γ), which can affect brain functions and induce depressive symptoms, were lower in the high-happiness group than in the low-happiness group. A negative correlation between the levels of perceived happiness and IFN-γ concentrations was also observed. Furthermore, we also found that experimentally induced happiness could reduce peripheral IFN-γ levels. CONCLUSIONS: These results revealed an association between the perception of happiness and systemic inflammation. Increased happiness may suppress the peripheral circulation of pro-inflammatory cytokines. © 2011 Neuroendocrinology Letters.

    This study examined neural features of emotional responses to errors. We specifically examined whether directed emotion regulation of negative emotion associated with error modulates action-monitoring functions of anterior cingulate cortex, including conflict monitoring, error processing, and error prevention. Seventeen healthy adults performed a continuous performance task during assessment by fMRI. In each block, participants were asked either to increase or decrease their negative emotional responses or to react naturally after error commission. Emotion regulation instructions were associated with modulation of rostral and dorsal anterior activity and of their effective connectivity following errors and conflict. Cingulate activity and connectivity predicted subsequent errors. These data may suggest that responses to errors are affected by emotion and that aspects of emotion and cognition are inextricably linked, even during a nominally cognitive task. © 2011 Psychonomic Society, Inc.

    The polymorphism of the serotonin transporter gene in the promoter region (5HTTLPR) has been considered to link with vulnerability to depression and anxiety. This paper introduces a series of our studies showing that this genetic polymorphism can explain portions of individual differences in stress reactivity at multiple levels: brain functions, peripheral physiological responses, and behaviors. Specifically: (a) carriers of double short (S) alleles, compared with carriers of at least one long (L) allele, show greater activation in the hypothalamus and larger reactivity in blood catecholamine, cortisol, and an inflammatory cytokine to acute stress; (b) carriers of double S alleles are more sensitive to punishment, and thus show poorer performance in a decision-making situation where they have to stick to a long-term correct option regardless of short-term punishment; and (c) carriers of double S alleles show greater activation of the amygdala and a correlation between amygdalar activity and an increase of natural killer cell proportion in blood when positive emotions are elicited. A possible model to explain the biological mechanisms underlying those phenomena is proposed and the ecological adaptive values of the 5HTTLPR genotypes are discussed. © Japanese Psychological Association 2011.

    Intact face perception is an important function for individual identification in highly socialized human community. Recent studies revealed that there are hereditary individual differences on the cognitive skills related to face identification, named congenital&frasl;hereditary prosopagnosia. The investigation on the congenital&frasl;hereditary prosopagnosia would advance our understanding of the face identification mechanism, however, has not been conducted with Japanese samples. The development of the Japanese version of the congenital&frasl;hereditary prosopagnosia screening scale is the first step of the congenital&frasl;hereditary prosopagnosia study in Japan. In this study, we attempted the translation of the original screening scale into Japanese, and also investigated the relationship between the score of scale and behavioral&frasl;physiological responses on face stimuli. As a result, we found highly internal consistency and test-retest reliability for the Japanese version of the congenital&frasl;hereditary prosopagnosia screening scale. Also we have revealed the score was related to some behavioral performances and ERP responses related to the self-face perception.

    In this study, we examined whether the feedback-related negativity (FRN) is associated with both subjective and objective (model-estimated) reward prediction errors (RPE) per trial in a reinforcement learning task in healthy adults n=25). The level of RPE was assessed by 1) subjective ratings per trial and by 2) a computational model of reinforcement learning. As results, model-estimated RPE was highly correlated with subjective RPE r=.82), and the grand-averaged ERP waves based on the trials with high and low model-estimated RPE showed the significant difference only in the time period of the FRN component p<.05). Regardless of the time course of learning, FRN was associated with both subjective and model-estimated RPEs within subject r=.47, p<.001; r=.40, p<.05) and between subjects r=.33, p<.05; r=.41, p<.005) only in the Learnable condition where the internal reward prediction varied enough with a behavior-reward contingency. © 2010 Elsevier B.V.

    Pre-attentive deviance detection in the visual environment has been known to be reflected by an event-related brain potential (ERP) component, deviant-related negativity. Recently, however, we demonstrated that deviant-related negativity comprises two, temporally and spatially overlapping ERP components, by using an experimental protocol consisting of oddball and equiprobable sequences [M. Kimura, J. Katayama, H. Ohira, E. Schröger, Visual mismatch negativity: new evidence from the equiprobable paradigm, Psychophysiology 46 (2009) 402-409]: (1) visual N1 that reflects a sensory, refractoriness-based deviance detection system and (2) visual mismatch negativity (MMN) that reflects a cognitive, memory-comparison-based deviance detection system. In the present paper, we further elucidated the neural generators of the visual N1 and visual MMN with standardized low-resolution brain electromagnetic tomography (sLORETA). Results showed that the visual N1 was involved in neural activations of the primary and nonprimary visual areas, while the visual MMN was involved in neural activations of the nonprimary visual areas and the prefrontal areas. These results suggest that the sensory and cognitive deviance detection systems subserved by distinct neural structures underlie our efficient pre-attentive visual deviance detection. © 2010 Elsevier Ireland Ltd.

    An emotional deficit in individuals with psychopathy has been regarded as a potential factor in the disinhibition of selfish behaviors, which can be an impediment to a successful life in human society. However, recent studies in the field of economics have made clear that emotional function is associated with irrational decision-making. In the present study, to test whether psychopathy may have a positive aspect in a social setting, we examined the decision-making of college students with high and low tendencies for psychopathy in the ultimatum game, which illustrates conflict between fairness and economic utility. We also investigated electrodermal responses to fair and unfair offers for each group. Compared to low psychopathic controls, individuals with a high tendency toward psychopathy more often choose economic utility by accepting unfair offers. Whereas controls more often exhibited an electrodermal response to unfair offers compared to fair offers, high psychopathic individuals did not show a similar difference between the types of offer. The results suggest that the affective deficit of psychopathy might be associated with insensitivity to unfairness and may contribute to a rational decision to accept unfair offers. Hence, psychopathy can be rational in some social situations. © 2010 Elsevier Ltd.

    Life choices (e.g., occupational choice) often include situations with two or more possible correct answers, thereby putting us in a situation of conflict. Recent reports have described that the evaluation of conflict might be crucially mediated by neural activity in the dorsal anterior cingulate cortex (dACC), although the reduction of conflict might rather be associated with neural activity in the medial prefrontal cortex (MPFC). What remains unclear is whether these regions mutually interact, thereby raising the question of their functional connectivity during conflict situations. Using psychophysiological interaction (PPI) analyses of functional magnetic resonance imaging (fMRI) data, this study shows that the dACC co-varied significantly higher with the MPFC during an occupational choice task with two possible correct answers when compared to the control task: a word-length task with one possible correct answer. These results suggest that the MPFC has a functional relation with dACC, especially in conflict situations where there is no objective correct answer. Taken together, this lends support to the assumption that the MPFC might be crucial in biasing the decision, thereby reducing conflict. © 2010 Elsevier Ireland Ltd.

    One important function of emotions is to guide decision making and behaviors for survival in complex environments. In the context of such reasoning, the somatic marker hypothesis (Damasio, 1994) has argued that bodily states are represented in specific brain regions, such as the insula, and would play critical roles in decision making. However, it still remains unclear what causal roles bodily states would play in decision making, and how the bodily states would change accompanying decision making. Thus, the aim of this article is to reconsider aspects of the brain and bodily states in decision making based on recent findings. Questions for future research are proposed based on such findings. © 2010 SAGE Publications and The International Society for Research on Emotion.

    The effects of anticipated threat situations and the valence of the stimuli on the deceleration of the phasic heart rate (HR) were investigated in a single experiment using an S1-S2 paradigm. There were certain S1 cues that were always expected to be followed by neutral pictures (S2 stimuli), and uncertain S1 cues that had a 50% probability of being followed by neutral or unpleasant pictures (S2 stimuli). Greater phasic HR deceleration was observed for S2 stimuli following uncertain S1 cues than for S2 stimuli following certain S1 cues, regardless of the valence of the S2 stimuli. This result suggests that an anticipated threat situation in which participants anticipate facing potentially unpleasant stimuli leads to the allocation of more attentional resources. Additionally, correlation analyses revealed that highly anxious individuals tended to show greater HR deceleration in response to unpleasant stimuli, possibly reflecting maladaptive attentional bias for threat stimuli. © 2010 Elsevier B.V.

    For our adaptive behavior in a dynamically changing environment, an essential task of the brain is to automatically encode sequential regularities inherent in the environment into a memory representation. Recent studies in neuroscience have suggested that sequential regularities embedded in discrete sensory events are automatically encoded into a memory representation at the level of the sensory system. This notion is largely supported by evidence from investigations using auditory mismatch negativity (auditory MMN), an event-related brain potential (ERP) correlate of an automatic memory-mismatch process in the auditory sensory system. However, it is still largely unclear whether or not this notion can be generalized to other sensory modalities. The purpose of the present study was to investigate the contribution of the visual sensory system to the automatic encoding of sequential regularities using visual mismatch negativity (visual MMN), an ERP correlate of an automatic memory-mismatch process in the visual sensory system. To this end, we conducted a sequential analysis of visual MMN in an oddball sequence consisting of infrequent deviant and frequent standard stimuli, and tested whether the underlying memory representation of visual MMN generation contains only a sensory memory trace of standard stimuli (trace-mismatch hypothesis) or whether it also contains sequential regularities extracted from the repetitive standard sequence (regularity-violation hypothesis). The results showed that visual MMN was elicited by first deviant (deviant stimuli following at least one standard stimulus), second deviant (deviant stimuli immediately following first deviant), and first standard (standard stimuli immediately following first deviant), but not by second standard (standard stimuli immediately following first standard). These results are consistent with the regularity-violation hypothesis, suggesting that the visual sensory system automatically encodes sequential regularities. In combination with a wide range of auditory MMN studies, the present study highlights the critical role of sensory systems in automatically encoding sequential regularities when modeling the world. © 2009 Massachusetts Institute of Technology.

    Cognitive science has regarded an individual's face as a form of representative stimuli to engage self-representation. The domain-generality of self-representation has been assumed in several reports, but was recently refuted in a functional magnetic resonance imaging study (Sugiura et al., 2008). The general validity of this study's criticism should be tested by other measures to compensate for the limitation of the time resolution of the blood-oxygen-level-dependent (BOLD) signal. In this article, we report an EEG study on the domain-generality of visual self-representation. Domain-general self-representation was operationally defined as the self-relevance common to one's own Face and Cup; three levels of familiarity, Self, Familiar, and Unfamiliar, were prepared for each. There was another condition, Visual Field, that manipulated visual hemifield during stimulus presentation, but it was collapsed because it produced no interaction with stimulus familiarity. Our results confirmed comparable phase resetting in both domains in response to familiarity manipulation, which occurred within the medial frontal area during 270-390 ms poststimulus and in the theta band. However, self-specific dissociation was observed only for Face. The results here support the conclusion that visual self-representation is domain-specific and that the oscillatory responses observed suggest evidence of face-specific visual self-representation. Results also revealed an inter-trial phase coherency decrease specifically for Self-Face within the right fusiform area during 170-290 ms poststimulus and in the alpha and theta band, suggesting reduced functional demand for Self-Face represented by sharpened networks. © 2010 Elsevier Inc.

    The authors investigated whether self-knowledge has a function to reduce conflict by biasing one of two choices during occupational choice (e.g., Which occupation do you think you could do better-dancer or chemist). In the three experiments, event-related brain potentials were recorded. Experiment I revealed that the amplitude of the conflict-related negativity (CRN) reflects strength of conflict during occupational choice. Results of Experiment 2 demonstrated that the CRN amplitude during occupational choice was smaller when self-knowledge was activated than when other-knowledge was activated. Experiment 3 showed that the CRN amplitude during occupational choice was decreased more when self-knowledge that biases one choice of occupation was activated than when self-knowledge that does not bias was activated. These results suggest that self-knowledge reduces conflict by biasing one of multiple choices in situations where two or more possible correct answers can be given.

    Limbic system activation that occurs when a person experiences several emotions is primarily represented by the amygdala output that influences autonomic brainstem nuclei that control autonomic nervous function, thus modulating the endocrine and immune systems. Amygdala activity is modulated by the serotonin transporter gene-linked polymorphic region (5HTTLPR); however, whether variations in 5HTTLPR influence central nervous and immune activities in response to positive stimuli remains unclear. Here, we found that seeing a favorite person induced significantly higher amygdala activity in individuals with the 5HTTLPR SS genotype than in others. This activity was positively correlated with changes in the NK cell proportion among peripheral lymphocytes. Thus, 5HTTLPR influences attraction and the associated interactions between the central nervous and immune systems in affectively positive situations. © 2009 Elsevier Ireland Ltd.

    To examine the functional association between brain and autonomic activities accompanying decision-making, we simultaneously recorded regional cerebral blood flow using 15O-water positron emission tomography and event-related brain potentials (ERPs) time-locked to feedback of reward and punishment, as well as cardiovascular parameters, during a stochastic decision-making task. We manipulated the uncertainty of outcomes in the task; specifically, we compared a condition with high predictability of reward/punishment (contingent-reward condition) and a condition with low predictability of reward/punishment (random-reward condition). The anterior cingulate cortex (ACC) was commonly activated in both conditions. Compared with the contingent-reward condition, the orbitofrontal and right dorsolateral prefrontal cortices and dorsal striatum were activated in the random-reward condition, where subjects had to continue to seek contingency between stimuli and reward/punishment. Activation of these brain regions correlated with a positive component of ERPs locked to feedback signals (feedback-related positivity), which showed an association with behavioral decision-making in the contingent-reward condition. Furthermore, cardiovascular responses were attenuated in the random-reward condition, where continuous attention and contingency monitoring were needed, and such attenuation of cardiovascular responses was mediated by vagal activity that was governed by the rostral ACC. These findings suggest that the prefrontal-striatal network provides a neural basis for decision-making and modulation over the peripheral autonomic activity accompanying decision-making. © 2009 Elsevier Inc.

    Limbic system activation that occurs when a person experiences several emotions is primarily represented by the amygdala output that influences autonomic brainstem nuclei that control autonomic nervous function, thus modulating the endocrine and immune systems. Amygdala activity is modulated by the serotonin transporter gene-linked polymorphic region (5HTTLPR); however, whether variations in 5HTTLPR influence central nervous and immune activities in response to positive stimuli remains unclear. Here, we found that seeing a favorite person induced significantly higher amygdala activity in individuals with the 5HTTLPR SS genotype than in others. This activity was positively correlated with changes in the NK cell proportion among peripheral lymphocytes. Thus, 5HTTLPR influences attraction and the associated interactions between the central nervous and immune systems in affectively positive situations. (C) 2009 Elsevier Ireland Ltd.

    To examine the functional association between brain and autonomic activities accompanying decision-making, we simultaneously recorded regional cerebral blood flow using (15)O-water positron emission tomography and event-related brain potentials (ERPs) time-locked to feedback of reward and punishment, as well as cardiovascular parameters, during a stochastic decision-making task. We manipulated the uncertainty Of Outcomes in the task; specifically, we compared a condition with high predictability of reward/punishment (contingent-reward condition) and a condition with low predictability of reward/punishment (random-reward condition).

    多くの意思決定研究では予測しやすいもしくは予測しにくい一つの正答がある事態について検討がなされてきた。意思決定に伴う結果が確率的に変化する, もしくは他者の決定により変化するために予測困難な事態(予測可能性が低い事態)は不確実下における意思決定として研究がなされてきた。このような意思決定とは異なり, 全く正答の存在しない事態における意思決定というものも存在する。本論文では, 一つの正答のある, そして正答のない事態における意思決定研究をレビューし, それらの研究において観察されている内側前頭前皮質内の活動部位の違いを比較した。その結果, 一つの予測可能性の低い正答のある意思決定と正答のない意思決定の両方で内側前頭前皮質の上部に活動が認められていることが明らかとなった。このことは不確実性という概念の再考とMPFCの機能についての示唆を与えるものである。

    The present study aimed to investigate the dissociable effects of two forms of self-focus on emotional and autonomic responses. One form is suppression, which includes the suppression of heart rate and self-evaluation of performance. The other is observation, which includes attention to one's own heart rate with no suppression and no evaluation. 26 undergraduate and graduate students from the Nagoya University campus (13 men, 13 women), ages 18 to 24 years (M = 20.7, SD=1.6) were recruited. Participants were provided with their own heart rate as feedback for 5 min., during which participants conducted a self-focus manipulation. Several days after the experimental session for one condition, the same participants conducted another experimental session for the other condition. Instruction to suppress enhanced physiological arousal and subsequent negative emotions; however, instruction to observe did not increase physiological arousal or negative emotions. © Perceptual and Motor Skills 2009.

    The present study investigated whether trait anxiety reduce the contribution of episodic retrieval to recognizing negative words. Behavioral and electrophysiological responses in anxious individuals were measured during an exclusion recognition task to compare with a previous report about control participants (Inaba et al., 2007). At test, participants were asked to respond "old" when an item had been included in a target study list. According to the process-dissociation framework, the difference in the waveforms for the "old" responses between target and non-target items is considered to be a measurement of recollection. It was shown to be the difference in the slow waves. As with the behavioral estimate of recollection, the difference in the slow waves at left-parietal area was smaller for negative items compared to other items in the anxiety group. This result was in contrast to a greater difference in the slow positivity for negative words in the control group. These findings suggest that excess old judgments for negative items in the anxious group might be associated with less recollective memory. © 2009 Elsevier B.V. All rights reserved.

    A short (S) variant, compared to a long (L) variant, of the promoter region of the serotonin transporter gene-linked polymorphic region (5HTTLPR) has been related to emotional hyper-reactivity. We tested whether the 5HTTLPR could modulate acute stress responses in the brain and, the cardiovascular and neuroendocrine systems. Ten Japanese male participants carrying double copies of the S alleles and 10 Japanese males carrying S and L alleles conducted a mental arithmetic task, and their regional cerebral blood flow by 15O positron emission tomography and cardiovascular and neuroendocrine parameters were measured. During the acute stress task, the participants with the SS alleles showed stronger reactivity in blood pressure and secretion of epinephrine, compared to the participants with the SL and LL alleles. Furthermore, the SS carriers showed greater activation in stress-related brain regions such as the hypothalamus, cerebellum, midbrain, and pulvinar compared to the SL and LL carriers during the acute stress task. The present findings indicated that the S allele of the 5HTTLPR is associated with greater brain and physiological reactivity to acute stress in Japanese men. © 2009 Informa Healthcare USA, Inc.

    Emotion-based behaviors in humans cannot be fully explained by economic rationality. Particularly, in the ultimatum game, which incorporates conflict between self-interest and fairness, negative emotions evoked by an unfair offer seem to promote an economically irrational decision. In accordance with this suggestion, the previous studies have reported that physiological arousal is associated with rejecting unfair offers. In the present study, we investigated electrocardiogram and electrodermal activities in individuals which received fair, advantageously unfair, and disadvantageously unfair offers to specify the relations of the orienting and the defensive responses with these offers and with the decisions to accept and reject them. The results indicated that when an offer that would be rejected was presented, heart rate initially decelerated more than when an offer that would be accepted was presented. Additionally, there was a linear relationship between the deceleration and unfairness of offers. On the other hand, such different patterns were not seen in late cardiac acceleration or electrodermal response. The results suggest that because of perception of disadvantage and unpleasantness in a social context, the orienting response is evoked when an offer will be rejected. In addition, these results are discussed regarding the effect of the autonomic activity in decision-making. © 2009 Elsevier B.V. All rights reserved.

    Recent studies in psychoneuroimmunology have indicated that proinflammatory cytokines cause several diseases and behaviors that overlap symptomatically with depression. It is known that the endogenous opioid peptide β-endorphin regulates proinflammatory cytokine secretion from peripheral immune cells via μ-opioid receptor-dependent mechanisms. Therefore, it is possible that the functional polymorphism of the μ-opioid receptor gene (OPRM1, SNP: A118G) influences peripheral circulating proinflammatory cytokine levels and the health-related quality of life (QOL) even in healthy populations. In this study, we compared the serum concentrations of several proinflammatory cytokines (interleukin-2 (IL-2), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and interferon-γ (IFN-γ)) and the health-related QOL between OPRM1 genotypes. Interestingly, serum concentrations of IL-6, TNF-α, and IFN-γ were significantly lower and the general health score was significantly higher in carriers of the G allele, who show a strong binding of β-endorphin to the μ-opioid receptor as compared to individuals without the G allele. Correlation analysis indicated that the general health score was negatively correlated with the IL-6 serum concentration. These results suggest that the sensitive endogenous opioid system in carriers of the G allele may suppress proinflammatory cytokine secretion from peripheral immune cells; consequently, it may influence the health perception. © 2009 Elsevier Inc.

    OBJECTIVES: Warm physical contact may positively influence our health and well-being; however, it has not been investigated yet whether serum proteins are influenced by warm physical contact in healthy couples. In this study, we focused on psychological and physiological effects of warm partner contact in healthy couples. METHODS: When participants freely kissed and hugged their romantic partners, they were asked to subjectively evaluate their present emotions. Furthermore, changes of serum proteins were determined by using ProteinChip surface enhanced laser desorption/ionization-time-of-flight-mass spectrometry (SELDI-TOF-MS). We characterized these proteins by using biochemical techniques combined with gel filtration high performance liquid chromatography (HPLC), reverse-phase HPLC, and sequencing analyses. RESULTS: Romantic couples became happier and less irritated after kissing and hugging. Accompanying these psychological changes, SELDI-TOF-MS indicated that the intensities of 66-k Da, 11.7-k Da, and 5.9-k Da serum proteins were increased. These proteins were identified as serum albumin and β2- microglobulin, and probably fibrinogen fragment. The feeling of happiness positively correlated and the feeling of irritation negatively correlated with intensities of serum albumin and β2-microglobulin. CONCLUSION: These results suggest that psychological stress may be reduced and we may feel happiness when we kiss and hug a romantic partner. Furthermore, these results also suggest that warm partner contact influences peripheral circulating proteins, more importantly, may promote health and well-being.

    It has been demonstrated that concentrations of pro-inflammatory cytokines such as interleukin-1β (IL-1β) and interleukin-6 (IL-6) are elevated by acute stress. Although several studies confirmed robust changes in IL-6, how acute stress affects other cytokines was less clear. Therefore, the present study simultaneously examined the effects of acute stress on several pro-inflammatory cytokines. Sixteen male participants were given the Trier Social Stress Test (TSST). Blood samples were collected at baseline, immediately after, and 30, 60, and 90 min after the TSST. IL-1β significantly increased immediately after the TSST and returned to the baseline level after 30 min. Additionally, this elevation of IL-1β was correlated with the perceived intensity of stress. These results showed that the concentration of IL-1β is rapidly regulated, and that elevation of the IL-1β level could possibly be attributed to transient mobilization of monocytes caused by sympathetic nervous activation. Moreover, a transient increase of IL-1β might be conveyed to the brain and play a role in forming negative emotional states. © 2009 Elsevier B.V. All rights reserved.

    Acute stress elicits redistribution of lymphocyte subsets, especially natural killer (NK) cells, probably for preparatory defense against potential invasion of antigens in fight-flight situations. We previously reported that regulation of lymphocyte redistribution is based on the evaluation of the controllability of a stressor (Kimura, K., Ohira, H., Isowa, T., Matsunaga, M., Murashima, S. 2007. Regulation of lymphocytes redistribution via autonomic nervous activity during stochastic learning. Brain Behav. Immun. 21, 921-934; Ohira, H., Isowa, T., Nomura, M., Ichikawa, N., Kimura, K., Miyakoshi, M., Iidaka, T., Fukuyama, S., Nakajima, T., Yamada, J. 2008. Imaging brain and immune association accompanying cognitive appraisal of an acute stressor. Neuroimage 39, 500-514). Specifially, lymphocyte redistribution is somewhat attenuated when a stressor is uncontrollable, probably to save biological energy in a situation where appropriate coping is unclear. We infer that this phenomenon might reflect top-down regulation over peripheral immune function by higher-ordered brain regions. To investigate the neural basis of such a phenomenon, we simultaneously recorded regional cerebral blood flow using 15O-water positron emission tomography and cardiovascular (blood pressure and heart rate), neuroendocrine (epinephrine, norepinephrine, and adrenocorticotropic hormone), and immune (proportions of NK cells and helper T cells in blood) indices in 16 male subjects who performed a stochastic learning task with manipulation of controllability (controllable vs. uncontrollable). Consistent with previous studies, the proportion of peripheral NK cells was attenuated in an uncontrollable stress condition. The dorsolateral prefrontal and orbitofrontal cortices were activated in the uncontrollable situation but not in the controllable condition, and additionally, these prefrontal brain regions significantly correlated with the degree of redistribution of NK cells in the uncontrollable condition. The results of the study suggest these brain regions are involved in both evaluation of the controllability of a stressor and regulation of immune function. © 2009 Elsevier Inc. All rights reserved.

    Recent studies have indicated that brain and gut activities are interrelated and exposure to several stressors, such as water-avoidance stress, stimulates the motor function of the gut through corticotropin-releasing factor (CRF)-signalling pathways in the brain. Central oxytocin is known to attenuate stress responses, including CRF expression in the brain. Here, we examined whether central oxytocin attenuated the acceleration of colonic motility induced by water-avoidance stress. A force transducer was attached to the distal colon of male rat, and the colonic motility and faecal pellet output were recorded while the rats were exposed to water-avoidance stress. Intracerebroventricular (i.c.v.) injections of oxytocin (5, 50 and 500 pmol) and the oxytocin receptor antagonist tocinoic acid (25 μg) were administered before exposure to water-avoidance stress, and the effect of oxytocin on colonic motor function was determined. Centrally administered oxytocin inhibited the accelerated colonic motility induced by water-avoidance stress. The effective dose ranged between 5 and 50 pmol on i.c.v. injection. Oxytocin also decreased the number of CRF-positive cells in the paraventricular nucleus and corticosterone release. The inhibitory effect of oxytocin on accelerated colonic motility was blocked by pretreatment with oxytocin receptor antagonist. Furthermore, centrally administered tocinoic acid enhanced the acceleration of colonic motility. These results suggested that endogenous central oxytocin may contribute to the regulation of colonic function and inhibit the brain CRF-signalling pathways targeting the gut, resulting in the inhibition of stress-induced colonic contractions. © 2009 Blackwell Publishing Ltd.

    Life choice (e.g. occupation choice) often includes situations with two or more possible answers. How does the brain respond to such conflict-ridden situations? We investigated whether the dorsal anterior cingulate cortex (dACC) evaluates the degree of conflict between possible answers. Additionally, we investigated whether the medial prefrontal cortex (MPFC) or the medial temporal lobe (MTL) has a function in behavior selection with plural possible answers. We used an occupational choice task (e.g. which occupation do you think you could do better?-dancer or chemist) with two possible answers and a word-length task (e.g. which word is longer?-dentist or comedian) that has a correct answer. The conflicts in each task were manipulated. Results showed that the dACC and the MTL were activated when the conflict during occupational choice was large, and that the MPFC and posterior cingulate cortex were activated more in the occupational choice task than in the word-length task. Our results show that the dACC evaluates the degree of conflict between possible answers, and that the MTL, MPFC, and posterior cingulate cortex have a function in behavior selection without an objective correct answer. It is thought that the MTL functions to reduce conflict when a large-conflict is detected in the dACC. Furthermore, the MPFC and posterior cingulate are thought to have a function of biasing any of the plural answers in behavior selection without an objective answer. © 2009 Elsevier Ireland Ltd.

    Medial prefrontal cortex (MPFC) activation has been observed in studies of many types related to emotion regulation, self and familiar other-knowledge, mentalizing, morality, reward, and uncertainty. Furthermore, the anterior cingulate cortex (ACC) and the lateral prefrontal cortex (LPFC), which have reciprocal connections with MPFC, are considered necessary for cognitive regulation. Based on these findings, Nakao, Takezawa, and Miyatani (2006) proposed an integrative explanation for MPFC function: MPFC has a function of representing a benchmark that reduces conflict among many possible answers by biasing either choice of behavior. In this article, we review studies related to MPFC function and the benchmark hypothesis with recent new findings. Additionally, we discuss emotion regulation, which was not described in Nakao et al. (2006), in relation to the benchmark hypothesis.

    Mitochondrial DNA (mtDNA) is a powerful tool for forensic casework when the resource is highly putrefied or very limited. It is important that mtDNA sequence databases continue to be generated and published, to extend mtDNA typing capability to additional populations and to increase the size of existing databases. The aim of this study was to analyze hypervariable region 1 (HV1) of mtDNA and establish a new database of mtDNA in Japanese population. Three hundred and ninety-four unrelated Japanese individuals were investigated. They were classified into 193 haplotypes based on HV1 sequence. Nucleotide substitutions were clustered in several positions and were 79% at 16,223, 50% at 16,362, and 29% at 16,189. Transition accounts for 81% of all the mutations and especially transition from cytosine to thymine (33%) was the most frequent substitution. 16,223-16,362 was observed in 34 individuals, following 16,129-16,223-16,362 in 29 individuals, and haplotype 16,223-16,278-16,362 in 14 individuals. Genetic diversity and random match probability in this population were estimated to 0.987% and 1.95%, respectively. In conclusion, HV1 of mitochondria sequence has a high discrimination power, but in addition to HV1, analysis of other region such as HV2 and HV3 are required in certain cases. © 2009 Elsevier Ireland Ltd.

    The present study aimed to investigate the dissociable effects of two forms of self-focus on emotional and autonomic responses. One form is Suppression, which includes the suppression of heart rate and self-evaluation of performance. The other is observation, which includes attention to one's own heart rate with no suppression and no evaluation. 26 undergraduate and graduate students from the Nagoya University campus (13 men, 13 women), ages 18 to 24 years (M=20.7, SD=1.6) were recruited. Participants were provided with their own heart rate as feedback for 5 min., during which participants conducted a self-focus manipulation. Several days after the experimental session for one condition, the same participants conducted another experimental session for the other condition. Instruction to suppress enhanced physiological arousal and subsequent negative emotions; however, instruction to observe did not increase physiological arousal or negative emotions.

    It is hypothesized that experiencing positive emotions such as pleasure leads to a perception of the body being in a positive state. This study demonstrated associations among positive mood, brain, and cardiovascular activities by simultaneously recording these activities when positive emotions were evoked in participants watching films revolving around a love story. Heart rate variability analysis revealed increased parasympathetic nervous activity while watching the film. The following brain regions were significantly activated in the positive condition relative to the control condition: medial prefrontal cortex, thalamus, superior temporal gyrus, inferior frontal gyrus, and cerebellum. Further, covariate analyses indicated that these brain regions were temporally associated with subjective positive mood. Activities of brain regions considered to be related to interoceptive awareness, such as the insular cortex, anterior cingulate cortex, amygdala, and orbitofrontal cortex, were also temporally associated with the cardiovascular change. These results suggest that while an individual experiences positive emotions, activities of the central nervous system and cardiovascular system may be interrelated, and the brain may perceive the body to be in a positive state. © 2009 Elsevier B.V.

    Metacognitive strategies of emotion regulation such as an objective perspective of one's self are known as primary factors in mindfulness intervention. Earlier studies, however, suggest that the effect of mindfulness differs because of the individual variability. In this study, we investigated the influence of the serotonin transporter gene polymorphism during the application of a metacognitive strategy of emotion regulation. Short (S) homozygotes showed more negative emotional states than SL individuals in both metacognition and control conditions. The high frequency of heart rate variability, however, increased in the metacognition condition only in S homozygotes. This result indicated that the metacognitive strategy of emotion regulation is more effective for increasing parasympathetic dominance in S homozygotes than in SL individuals. © 2009 Wolters Kluwer Health|Lippincott Williams & Wilkins.

    In visual oddball studies, deviant compared to standard stimuli elicited a posterior negative ERP at around 100-250 ms. To determine the underlying processes of the negativity, we used the equiprobable sequence in which bar stimuli of five types of orientation were presented with equal probabilities (control 20% each) as well as the oddball sequence in which two stimuli with the closest orientation were presented with different probabilities (deviant 20% and standard 80%). Deviant compared to standard stimuli elicited two negativities at around 100-150 ms with no hemispheric dominance and 200-250 ms with right hemispheric dominance, while deviant compared to control stimuli elicited only a negativity at around 200-250 ms with right hemispheric dominance. These results suggest that the early negativity reflects refractory effect, while the late negativity reflects memory-comparison-based change detection effect (visual mismatch negativity).

    By using electroencephalogram, we aimed at identifying the neural oscillations corresponding to two subcomponents of the visuotactile congruency process, facilitation and interference effects. The participants identified the location of the tactile stimulus presented at their index finger or thumb while ignoring simultaneous visual stimuli presented at the same (congruent) or different (incongruent) finger. Significant differences in reaction time were found between the congruent or incongruent condition and the unimodal baseline condition, indicating two different effects of visuotactile interaction. Electroencephalogram results showed significant increases in the γ-band response in the congruent condition and in the θ-band response in the incongruent condition. These results suggest two systems of multisensory interaction. © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins.

    The rubber hand illusion represents an illusory experience during the mislocalization of own hand when correlated visuotactile stimuli are presented to the actual and fake hands. The visuotactile integration process appears to cause this illusion; the corresponding brain activity was revealed in many studies. In this study, we investigated the effect of the rubber hand illusion on the crossmodal integration process by measuring EEG. The participants who experienced less intensive illusion showed greater congruency effect on reaction time (RT), greater power increase at the parietal zero electrode (Pz) and smaller interelectrode synchrony of the gamma band activity. On the other hand, the participants who experienced more intense illusion showed greater interelectrode synchrony. The results suggested that the gamma band activity in the parietal area reflects the visuotactile integration process and that its synchrony causes the illusory intensity. Crown Copyright © 2008.

    A short (S) variant, compared to a long (L) variant, of the promoter region of the serotonin transporter gene-linked polymorphic region (5HTTLPR) has been related to emotional hyper-reactivity. We tested whether the 5HTTLPR could modulate acute stress responses in the brain and, the cardiovascular and neuroendocrine systems. Ten Japanese male participants carrying double copies of the S alleles and 10 Japanese males carrying S and L alleles conducted a mental arithmetic task, and their regional cerebral blood flow by &lt;SU15&lt;/SUO positron emission tomography and cardiovascular and neuroendocrine parameters were measured. During the acute stress task, the participants with the SS alleles showed stronger reactivity in blood pressure and secretion of epinephrine, compared to the participants with the SL and LL alleles. Furthermore, the SS carriers showed greater activation in stress-related brain regions such as the hypothalamus, cerebellum, midbrain, and pulvinar compared to the SL and LL carriers during the acute stress task. The present findings indicated that the S allele of the 5HTTLPR is associated with greater brain and physiological reactivity to acute stress in Japanese men.&lt;/.

    Two types of focusing strategies on body information have been proposed. One is maladaptive focusing, involving suppressing one's own body sensations and evaluating one's own performance, and the other is adaptive, involving focusing on one's own body sensations without suppressing or evaluating them. The present study revealed that the maladaptive focusing strategy decreased parasympathetic activity and enhanced following negative emotion. Additionally, we investigated the influence of a serotonin transporter gene polymorphism on the two types of emotion regulation. As a result, participants with SS alleles of the serotonin transporter gene showed more negative emotions in the maladaptive than in the adaptive focusing manipulation associated with reducing parasympathetic activity. In contrast, although participants with L alleles showed reduced parasympathetic activity in the maladaptive condition, no such differences were observed in subjective emotions between the conditions. These results are consistent with the evidence of greater emotion regulation ability in individuals with L alleles compared to those with S alleles.

    The change in hormonal and immune state of university male students who were engaged in his graduation examination was investigated as a behavioral medicine study targeting on chronic stress. With regard to biomarkers of human hormonal and immune state, salivary secretory substances, Immunoglobulin A (IgA), Cortisol, Chromogranin (CgA), and dehydroepiandrosterone (DHEA), were assayed about a week before and 2 weeks after the day of oral defense of the graduation examination for 20 male students. As a result, the salivary immune substance, IgA, significantly decreased (p<0.001), while other biomarkers showed no significant change. In conclusion, it was suggested that IgA can be a promising candidate for a chronic stress marker.

    Change blindness studies using explicit behavioral measures have revealed that humans are remarkably poor at explicitly detecting changes between two successive visual images until focused attention is drawn to the changes, which supports the notion that outside the range of focused attention, our mental representations of the visual world are so volatile as to be unable to support detection of changes. However, change blindness studies using implicit behavioral measures have revealed that changes outside the range of focused attention might be detected even in the absence of awareness, which supports the possibility that our mental representations are not so volatile as has been suggested. The purpose of the present study was to provide further evidence for implicit change detection using event-related brain potentials (ERPs). For this purpose, we compared ERPs elicited on trials where color changes were present but participants failed to report the presence of changes (Change blindness trials) and ERPs on trials where changes were absent and participants correctly did not report the presence of changes (No-change trials). The result showed that compared to No-change trials, Change blindness trials elicited a frontal/central positivity at around 160-180 ms, which is highly consistent with the result of Fernandez-Duque et al. [D. Fernandez-Duque, G. Grossi, I.M. Thornton, H.J. Neville, Representation of change: separate electrophysiolocal markers of attention, awareness, and implicit processing, J. Cogn. Neurosci. 15 (2003) 491-507] who firstly reported an ERP correlate of implicit change detection. This result provides further evidence for implicit change detection, which supports the notion that even outside the range of focused attention, our mental representations of the visual world are robust at least enough to support implicit detection of changes. © 2008 Elsevier Ireland Ltd.

    Recent studies demonstrated that an acute psychological stressor elicited transient changes in lymphocyte redistribution. Earlier studies had established that CD3-CD16+CD56+ natural killer cells (NK cells) increased remarkably in peripheral blood circulation and that the amount of lymphocyte redistribution in NK cells was dependent on the CD62L expression density.
    Specifically, CD62L- cells were mobilized more pronouncedly than were CD62L+ cells. These results led us to hypothesize that such different reactivity causes different temporal characteristics between CD62L+ and CD62L- lymphocyte subsets.
    The present study was conducted to examine this issue. Ten female participants experienced a 10-minute baseline period and performed a 10-minute mental arithmetic task as an acute psychological stressor. Blood samples for measuring the proportions of CD62L+ or CD62L- NK cells and CD62L+ or CD62L- T cells were obtained immediately after each period and every 2 min during the task. As expected, CD62L+ and CD62L- NK cells showed different reactivity in response to the stressor and showed different temporal characteristics. That is, the elevation of CD62L- NK cells reached a significant level at I min after the initiation of the stressor, while CD62L+ NK cells took 8 min to show a tendency of elevation. Although CD3+ T cells showed different reactivity between CD62L cell types, they did not show different temporal characteristics. These findings suggest that the expression of CD62L modulates not only the amount of redistribution but also the temporal characteristics of the redistribution of NK cells. (C) 2008 Elsevier B.V.

    While faces are recognized viewpoint-dependently, familiar faces are recognized in a relatively viewpoint-independent manner. We conducted a cognitive ERP experiment to investigate the effect of viewpoint-independence for familiar-face recognition. The present results showed that facial angle differences were reflected by N170 latency and N250 amplitude. Furthermore, the N250 difference was attenuated in the left hemisphere for famous faces and in the right hemisphere for one's own face. We concluded that familiar faces are first recognized viewpoint-dependently, but then are represented viewpoint-independently. The laterality difference observed in N250 may be related to a self-relevant process in the right hemisphere, while a familiarity process is associated with the left hemisphere.

    Recent studies on psychoneuroimmunology have indicated that positive psychological events are related to immune functions; however, limited information is available regarding associations among the central nervous, endocrine, and immune systems when positive emotions are elicited. In the present study, we demonstrated associations among these systems by simultaneously recording brain, endocrine, and immune activities when positive emotions were evoked in participants as they watched films featuring their favorite persons. Interestingly, the activity of peripheral circulating natural killer cells and the peripheral dopamine level were elevated while participants experienced positive emotions, and these values were positively correlated. The following brain regions were significantly activated in the positive condition relative to the control condition: medial prefrontal cortex, thalamus, hypothalamus, subcallosal gyrus, posterior cingulate cortex, superior temporal gyrus, and cerebellum. Further, covariate analyses indicated that these brain regions were temporally associated with endocrine and immune activities. These results suggest that while an individual experiences positive emotions, the central nervous, endocrine, and immune systems may be interrelated and attraction for favorite persons may be associated with the activation of the innate immune function via the dopaminergic system.

    Recent studies on psychoneuroimmunology have indicated that positive psychological events are related to immune functions; however, limited information is available regarding associations among the central nervous, endocrine, and immune systems when positive emotions are elicited. In the present study, we demonstrated associations among these systems by simultaneously recording brain, endocrine, and immune activities when positive emotions were evoked in participants as they watched films featuring their favorite persons. Interestingly, the activity of peripheral circulating natural killer cells and the peripheral dopamine level were elevated while participants experienced positive emotions, and these values were positively correlated. The following brain regions were significantly activated in the positive condition relative to the control condition: medial prefrontal cortex, thalamus, hypothalamus, subcallosal gyrus, posterior cingulate cortex, superior temporal gyrus, and cerebellum. Further, covariate analyses indicated that these brain regions were temporally associated with endocrine and immune activities. These results suggest that while an individual experiences positive emotions, the central nervous, endocrine, and immune systems may be interrelated and attraction for favorite persons may be associated with the activation of the innate immune function via the dopaminergic system. © 2007 Elsevier Inc.

    Acute stress elicits multiple responses in autonomic, endocrine, and immune systems. Cognitive appraisal is believed to be one important modulator of such stress responses. To investigate brain substrates of crosstalks between the homeostasis-maintaining systems accompanying appraisal of stressor controllability, we simultaneously recorded regional cerebral blood flow (rCBF) using 15O-water positron emission tomography, cardiovascular indices (heart rate (HR) and blood pressure (BP)), neuroendocrine indices (concentrations of epinephrine, norepinephrine, and adrenocorticotropic hormone (ACTH) in blood), and immune indices (proportions of subsets of lymphocytes (NK cells, helper T cells, cytotoxic T cells, and B cells) in blood), in 11 male subjects who performed a mental arithmetic task with either high controllability (HC) and low controllability (LC). The LC task resulted in less sense of control in subjects than the HC task. Significant increases of rCBF in the medial and lateral orbitofrontal cortices (OFC), and in the medial and lateral prefrontal cortices (MPFC, LPFC) were observed by subtracting the HC task from the LC task. More importantly, significant positive correlations between rCBF and HR, BP, and NK cells were commonly found in the OFC and MPFC during the LC tasks, but not during the HC tasks. The present results showed for the first time that the prefrontal neural network including the OFC and MPFC might be one pivotal region for bi-directional functional association between the brain and peripheral autonomic and immune activities accompanying appraisal of an acute stressor. © 2007 Elsevier Inc.

    Amnesia is the main phenomenon in dissociative experiences. The present study investigated whether amnesia in participants with frequent dissociative experiences depended on state-dependent memory. Undergraduates scoring high (n = 32) or low (n = 32) on the Dissociative Experiences Scale Version-II (DES-II) participated in this experiment. Mood induction and a remember/know task were used in a typical mood-independent memory design. In the inconsistent mood state condition, participants in the high DES group showed decreased memory performance compared to the low DES group. These results were attributed to the recollection components of recognition and not to the familiarity component. Therefore we concluded that the normal population with highly frequent dissociative experiences showed strong state-dependent memory and had a memory bias in the recollection component of memory.

    Cloninger's theory is that specific dimensions of temperament are associated with single neurotransmitter systems, and it is based on neurophysiologic and genetic approaches to the human traits. It suggests that overexpression of temperament could cause psychiatric illness. Based on this theory, we examined the correlation between reward dependence (RD) trait, measured with the Temperament and Character Inventory, and 5 polymorphisms in genes of norepinephrine pathways, ADRB1, COMT, PNMT, SLC18A1, and SLC6A2, in 85 Japanese female nursing students. We found that rs3764351 in PNMT was significantly associated with RD on Fisher's exact test (P = .029, Pcorr = .236). When haplotype analysis was performed for rs3764351 and rs876493 polymorphisms in the 5′ flanking region of PNMT, 3 haplotypes were identified. Rs3764351 itself appeared to be correlated with RD in the present study of a specific population, although we could not demonstrate an association between RD and any of the haplotypes. Our findings have implications for the understanding of temperament using neurophysiologic approaches. © 2008 Elsevier Inc. All rights reserved.

    Several studies reported that redistribution of lymphocyte subsets, especially CD3-CD16+CD56+ natural killer (NK) cells, was elicited by acute psychological stress tasks. It is known that lymphocyte redistribution was regulated based on active or passive emotional coping strategies, which can be elicited dependent on controllability of a stressor. Controllability can be evaluated gradually by learning of a contingency between actions and outcomes. Therefore, lymphocyte redistribution can be determined by learning of the contingency. To examine this issue, we used a stochastic learning task as an acute stress task and divided twenty healthy participants into reinforcement or yoked groups. Between the two groups, only whether they could learn the contingency was manipulated. As a result, patterns of changes in the NK cell numbers differed between the groups; NK cells remarkably increased at first and then gradually decreased to the baseline in the reinforcement group while the yoked group showed a moderate but sustained increase of NK cells. These patterns of changes in the NK cells were completely parallel with changes of the cardiovascular parameters but not with secretion of catecholamines. The present results suggest that cardiovascular and immune reactivity can be modulated along with progresses of adaptation for an acute stressor. (C) 2007 Elsevier Inc. All rights reserved.

    Psychopathologies such as depression and anxiety have been associated with self-consciousness, a trait focusing on the self in terms of emotions and social images. A technique designed to shift attention away from the self tends to reduce anxiety, so the present purpose was to assess the effect of self body-state information on an individual's emotional and autonomic activity. 24 undergraduate and graduate students (10 men and 14 women), ages 19 to 27 years (M = 22.1, 5D = 2.5), were recruited as subjects. Focusing on body-state during an anxiety-inducing situation led to an increase of low to high frequency ratio of heart-rate variability which reflected cardiac sympathovagal balance. That is, attending to one's own bodily states enhanced relative sympathetic activity compared to parasympathetic activity, which can be interpreted as one of the physiological emotional responses elicited by anxiety. © Perceptual and Motor Skills 2007.

    The present study investigated the abnormalities of cardiovascular responses to contextual or explicit emotional stimuli with respect to the two facets of psychopathy in a Japanese undergraduate population assessed by a Japanese version of the Primary and Secondary Psychopathy Scales. In study 1, recording heart rate and fingertip skin temperature while the participants watched an unpleasant movie, we found that the participants with high tendencies toward antisocial behavior (n = 16) showed smaller reactivity than those with low tendencies toward antisocial behavior (n = 16). By contrast, in study 2, heart rate orienting responses to affective slides were recorded, and the participants with high tendencies toward emotional detachment (n = 15) showed smaller responses to unpleasant slides than those with low tendencies toward emotional detachment (n = 16). Consistent with previous studies which recorded skin conductance and startle eye blink with psychopaths, these findings using a non-institutionalized sample also suggest that affective dysfunction in psychopathy is based on two specific physiological mechanisms.

    The integration of multimodal stimuli has been regarded as important for the promotion of adaptive behavior. Although recent work has identified brain areas that respond to multimodal stimuli, the temporal features are not clear yet. Earlier event-related potential studies revealed crossmodal attention effects, but did not focus on mechanisms underlying crossmodal integration. Here, electroencephalography (EEG) activity in the gamma band was considered as a correlate of multimodal integration. Participants localized a tactile stimulus on their fingers while seeing visual stimuli on rubber hands with the same posture as their hands. EEG analyses using wavelet transform suggested that interelectrode phase synchrony in the gamma-band range (40-50 Hz) was related to behavioral indices of the intermodal illusion under consideration. The findings suggest a role of high-frequency oscillations in the integrative processing of stimuli across modalities. Copyright © 2007 Society for Psychophysiological Research.

    We performed an event-related potential study to investigate the self-relevance effect in object recognition. Three stimulus categories were prepared: SELF (participant's own objects), FAMILIAR (disposable and public objects, defined as objects with less-self-relevant familiarity), and UNFAMILIAR (others' objects). The participants' task was to watch the stimuli passively. Results showed that left-lateralized N250 activity differentiated SELF and FAMILIAR from UNFAMILIAR, but SELF and FAMILIAR were not differentiated. In the later time-course, SELF was dissociated from FAMILIAR, indicating the self-relevance effect in object recognition at this stage. This activity did not show consistent lateralization, in contrast to previous studies reporting right lateralization in self-relevant face and name recognition. We concluded that in object recognition, self-relevance was processed by higher-order cognitive functions later than 300ms after stimulus onset.

    The positive-going shift of event-related potential (ERP) components that occur when recognizing emotional words has been thought to be due to valence effects on either recollection or familiarity. This study investigated the independent contributions of recollection and familiarity on recognition of emotional words in order to examine which is thus responsible for the greater magnitude of ERP components seen in response to recognition of emotional, as opposed to neutral words. ERPs were measured while participants completed an exclusion recognition task. In the test phase, participants were required to respond "old" only to target items, which were included in one of two lists that were presented in the study phase. They were also asked to respond "new" to distracters and non-target items that were in the other previously presented list. "Old" responses to targets and non-targets were contrasted with an ERP analysis. Results suggested that the late positivity reflected recollection. The magnitude of this positivity, elicited around the left parietal area, was greater for negative stimuli compared to neutral and positive stimuli. The findings of the present study suggested that enhanced recollection of negative words may contribute to increased magnitudes of components such as the LPC. The emotional valence of words may have separate behavioral and electrophysiological effects on recollection and familiarity. © 2006 Elsevier B.V. All rights reserved.

    Although the taxonomy of click beetles (family Elateridae) has been studied extensively, inconsistencies remain. We examine here the relationships between species of Elateridae based on partial sequences of nuclear 28S ribosomal DNA. Specimens were collected primarily from Japan, while luminous click beetles were also sampled from Central and South America to investigate the origins of bioluminescence in Elateridae. Neighbor-joining, maximum-parsimony, and maximum-likelihood analyses produced a consistent basal topology with high statistical support that is partially congruent with the results of previous investigations based on the morphological characteristics of larvae and adults. The most parsimonious reconstruction of the "luminous" and "nonluminous" states, based on the present molecular phylogeny, indicates that the ancestral state of Elateridae was nonluminous. This suggests that the bioluminescence in click beetle evolved independent of that of other luminous beetles, such as Lampyridae, despite their common mechanisms of bioluminescence. © 2006 Elsevier Inc.

    Objectives: Shinrin-yoku (walking and/or staying in forests in order to promote health) is a major form of relaxation in Japan; however, its effects have yet to be completely clarified. The aims of this study were: (1) to evaluate the psychological effects of shinrin-yoku in a large number of participants; and (2) to identify the factors related to these effects. Methods: Four hundred and ninety-eight healthy volunteers took part in the study. Surveys were conducted twice in a forest on the same day (forest day) and twice on a control day. Outcome measures were evaluated using the Multiple Mood Scale-Short Form (hostility, depression, boredom, friendliness, wellbeing and liveliness) and the State-Trait Anxiety Inventory A-State Scale. Statistical analyses were conducted using analysis of variance and multiple regression analyses. Results: Hostility (P<0.001) and depression (P<0.001) scores decreased significantly, and liveliness (P=0.001) scores increased significantly on the forest day compared with the control day. The main effect of environment was also observed with all outcomes except for hostility, and the forest environment was advantageous. Stress levels were shown to be related to the magnitude of the shinrin-yoku effect; the higher the stress level, the greater the effect. Conclusions: This study revealed that forest environments are advantageous with respect to acute emotions, especially among those experiencing chronic stress. Accordingly, shinrin-yoku may be employed as a stress reduction method, and forest environments can be viewed as therapeutic landscapes. Therefore, customary shinrin-yoku may help to decrease the risk of psychosocial stress-related diseases, and evaluation of the long-term effects of shinrin-yoku is warranted. © 2006.

    l-Theanine is an amino acid contained in green tea leaves which is known to block the binding of l-glutamic acid to glutamate receptors in the brain. Because the characteristics of l-Theanine suggest that it may influence psychological and physiological states under stress, the present study examined these possible effects in a laboratory setting using a mental arithmetic task as an acute stressor. Twelve participants underwent four separate trials: one in which they took l-Theanine at the start of an experimental procedure, one in which they took l-Theanine midway, and two control trials in which they either took a placebo or nothing. The experimental sessions were performed by double-blind, and the order of them was counterbalanced. The results showed that l-Theanine intake resulted in a reduction in the heart rate (HR) and salivary immunoglobulin A (s-IgA) responses to an acute stress task relative to the placebo control condition. Moreover, analyses of heart rate variability indicated that the reductions in HR and s-IgA were likely attributable to an attenuation of sympathetic nervous activation. Thus, it was suggested that the oral intake of l-Theanine could cause anti-stress effects via the inhibition of cortical neuron excitation. © 2006 Elsevier B.V. All rights reserved.

    In the present study, we investigated the gamma band response and its phase synchrony between electrodes in alexithymia, which is characterized by a disability in identifying and describing feelings. Individuals with high and low alexithymia scores were selected according to the scores on the 20-item Toronto Alexithymia Scale. EEG was recorded from alexithymic and nonalexithymic persons viewing emotionally negative or neutral stimuli. Nonalexithymic persons exhibited increased gamma band power and phase synchronization at the 400-450-ms time window when processing emotionally negative stimuli. Neither enhanced gamma band power nor phase synchronization was observed in alexithymic persons in the negative emotion condition. These results suggest that gamma band activity reflects emotional processing, and alexithymic persons may have a deficit in communication between brain regions or in the utilization of memory or emotional information during the processing of emotional stimuli.

We took saliva samples to measure salivary cortisol (SC) before the first session, after the first session, and after the second session. Subjects were asked to complete the short form of the Multiple Mood Scale (MMS) questionnaire before the first session and after the second session. The shortened form of Betts' Questionnaire upon Mental Imagery (QMI) was collected once before the first session, and vividness of the imagery was measured using a visual analogue scale once after the second session.

    Conclusions center dot Unpleasant information, a cause of mental stress, is replaced by a comfortable image, and this replacement affects a participant's SC level. The greater one's imagery ability is, the more successful the displacement of stress and the shift toward a comfortable mental and emotional state will be. This study provides a basis for explaining the mechanism through which relaxation by means of guided imagery is effective in reducing stress.

    Recent neuroimaging studies have shown that several prefrontal regions play critical roles in inhibiting activation of limbic regions during voluntary emotion regulation. The present study aimed to confirm prior findings and to extend them by identifying the frontal neural circuitry associated with regulation of peripheral physiological responses during voluntary emotion suppression. Ten healthy female subjects were presented with affectively positive, neutral, and negative pictures in each of an Attending and Suppression task. Regional cerebral blood-flow changes were measured using 15O-water positron emission tomography, and autonomic (heart rate: HR, skin conductance response: SCR) and endocrine (adrenocorticotropic hormone: ACTH) indices were measured during both tasks. The left amygdala and the right anterior temporal pole were activated during the Attending task, whereas activation was observed in the left lateral prefrontal cortex (LPFC), including the adjacent medial prefrontal cortex (MPFC), and medial orbitofrontal cortex (MOFC) during the Suppression task. In the Attending task, activation in the amygdala and MOFC positively correlated with magnitudes of the SCR and ACTH responses. Emotion suppression elicited enhancement of SCR and the strength of the effect positively correlated with activation in the MOFC. These results suggest that the MOFC plays a pivotal role in top-down regulation of peripheral physiological responses accompanying emotional experiences. © 2005 Elsevier Inc. All rights reserved.

    This study, using a triadic-yoked design, clarified the effects of controllability of acute stress on responses of immune, cardiovascular (heart rate and blood pressure), and cortisol activities. Forty-three women in their follicular phase completed a mental arithmetic task as a stressor in which controllability was manipulated by correct or yoked-bogus feedback. The task decreased proportions of CD3+ T cells, CD4+ T cells, and CD19+ B cells, whereas it increased the numbers of white blood cells, lymphocytes, natural killer (NK) cells, and NK cell activity (NKCA). Our main hypothesis that greater immune and cardiovascular responses to the task would be obtained under the uncontrollable condition than under the controllable condition was not supported. However, the uncontrollable stress condition, but not the controllable situation, led to higher correlations between heart rate or blood pressure, and various immune parameters. On the other hand, parameters of heart rate variability reflecting sympathetic and parasympathetic activities showed significant correlations only with NKCA. These results suggest that immune responses were most directly associated with cardiovascular activities under the uncontrollable condition. © 2005 Elsevier B.V. All rights reserved.

    Functional association of brain, autonomic, and endocrine activities accompanying experience of emotions and self regulation of emotions were examined by simultaneous recording. As results, activation of the amygdale was found during emotion experiences, and further the degree of activation in the amygdale could predict levels if skin conductance responses (sympathetic activity) and secretion of ACTH (endocrine activity). On the other hand, the lateral prefrontal and orbitofrontal cortices were involved in emotion regulation, and those parts of the brain could suppress activation of the amygdala.

    Activities of brain, cardiovascular, endocrine, and immune systems were measured simultaneously and their functional association was examined during an acute stress task where controllability of the stressor was manipulated experimentally. Results revealed that neural network in the orbitofrontal and medial prefrontal cortices is involved in evaluation of controllability and top down modulation over peripheral physiological responses.

    Sympathetic nervous activity plays a prominent role in acute stress responses in the immune system, enhancement of innate immunity and suppression of specific immunity. The present study was conducted to examine the temporal characteristics of such immune responses to acute stress and to determine their association with sympathetic activity in detail. For this purpose, 15 female undergraduates engaged in a continuous mental arithmetic task for 14 min, and we collected their blood samples for immune indices (CD3+ T cells, CD4+ T cells, NK cells) each 3 min during the task and saliva samples before and after the task. Our results showed that the proportion of Natural Killer cells (NK cells) increased even 2 min after initiation of the task, whereas proportions of CD3+ and CD4+ lymphocytes decreased 8 min after initiation of the task. Moreover, we found significant correlations between cardiovascular activity and the variations of immune indices. © 2005 Elsevier B.V. All rights reserved.

    Sympathetic nervous activity plays a prominent role in acute stress responses in the immune system, enhancement of innate immunity and suppression of specific immunity. The present study was conducted to examine the temporal characteristics of such immune responses to acute stress and to determine their association with sympathetic activity in detail. For this purpose, 15 female undergraduates engaged in a continuous mental arithmetic task for 14 min, and we collected their blood samples for immune indices (CD3+ T cells, CD4+ T cells, NK cells) each 3 min during the task and saliva samples before and after the task. Our results showed that the proportion of Natural Killer cells (NK cells) increased even 2 min after initiation of the task, whereas proportions of CD3+ and CD4+ lymphocytes decreased 8 min after initiation of the task. Moreover, we found significant correlations between cardiovascular activity and the variations of immune indices. (c) 2005 Elsevier B.V. All rights reserved.

    There are no clear reports of electrophysiological evidence of the facilitating effect of negative valence on word recognition. However, behavioral psychological studies have suggested that negative words can be recognized more accurately than positive and neutral words. This study aimed to examine whether, and if so how, the valence of words could influence accuracy and event-related potentials (ERPs) in a recognition task. ERPs were recorded from 20 healthy subjects during performance of a word recognition task. We found a behavioral advantage in discriminability between old and new items for negative words. As for ERPs, the positive-going shift was evident for correct responses to targets in late latency at midline and left centro-parietal sites. Additionally, the magnitude of this component was greatest for negative targets, next for positive targets, and least for neutral targets. The findings offer support for the idea that negative content greatly accelerates recognition memory compared to positive and neutral words.

    Feedback negativity is a negative component of the event-related brain potential observed 250-300 ms after feedback stimuli. The present study investigated the effects of value (correct or incorrect) and reward magnitude (no, small or large) on feedback negativity and P300. Feedback negativity was larger after incorrect feedback than after correct feedback, irrespective of reward magnitude. In contrast, P300 amplitude increased with reward magnitude, irrespective of value. The amplitude of feedback negativity was correlated with a trait score of negative affect and not positive affect, whereas P300 amplitude was correlated with positive affect and not negative affect. These results suggest that value and reward magnitude are processed separately in the brain. (c) 2005 Lippincott Williams F Wilkins.

    Innate immune cells such as natural killer increase and acquired immune cells such as T cells decrease accompanying acute stress (redistribution of lymphocytes). This study examined effects of controllability of an acute stressor on the redistribution of lymphocytes. It was clarified that redistribution is suppressed in an uncontrollable situation. We further clarified mediating mechanisms of the phenomena and discussed significance of the phenomena in adaptation.

    Although the neural basis of the unconscious priming effect has previously been investigated, the results of these studies have possibly been contaminated by a conscious priming effect. The aim of the present study was to dissociate the effects of conscious and unconscious priming on event-related potential (ERP) by using the process-dissociation procedure. A prime word was presented briefly, followed by a word-stem, in each trial. Under the inclusion condition, subjects were instructed to complete the word-stem using the prime word, while under the exclusion condition subjects were asked to complete the word-stem with a word not seen as prime. The behavioral priming effect was obtained under both conditions, indicating that the prime words were processed unconsciously and influenced the word-stem completion task. We found that two ERP components were affected by repetition priming. First, the N400 amplitude was decreased by word repetition under the inclusion condition, but not under the exclusion condition. This result suggests that N400 would reflect conscious lexical processing, but not unconscious lexical activation. Second, the negativity at left front lateral region was enhanced by word repetition under the exclusion condition. We discuss this finding herein in relation to the activity of the left inferior prefrontal cortex with regard to word semantic processing. (c) 2004 Elsevier Ltd. All rights reserved.

    Acute experimental Stressors transiently increase volume of secretory immunoglobulin A (s-IgA) in saliva. The present study examined buffering effects of social support on response of s-IgA to a brief psychological stress (giving a public speech), 24 women were divided at random into three groups, an emotional support group, an informational support group and a no-support group (control). For each group, s-IgA measures were obtained from each person under baseline conditions, during preparation of a speech when social support or no support was given, immediately after the speech and during a 'recovery' period. Level of s-IgA in the control group significantly elevated during preparation for the speech and just after the speech compared to baseline, suggesting that the speech task stimulated secretory immune function. On the other hand, the subjects in the emotional support group showed increased s-IgA during the preparation period but secretion of s-IgA rapidly returned to the baseline after the speech task. Secretion of s-IgA in the informational social support group was unchanged at any measurement point. These results suggest that social support attenuates the affect of a Stressor on somatic state.

    Previous studies have indicated that expression of negative emotions facilitates mental and physical health and inhibition of negative emotions increases susceptibility to illness. This study was conducted to examine whether those findings can be expanded to populations with non-Western cultural backgrounds. Specifically, we explored effects of expression and inhibition of negative emotions on health, mood states, and mucosal immune function in mildly depressed Japanese individuals. 16 depressed and 16 nondepressed female undergraduates were required either to write about their unpleasant experiences and superficial topics or to suppress any emotional responses and thoughts about them. Secretory immunoglobulin A (s-IgA) in saliva and psychological indices were measured at an experimental session and at a follow-up 1 wk. later. Beneficial effects of expression of emotions on subjective health were indicated in the nondepressed group, whereas harmful effects of inhibition on subjective health were shown in the depressed group. Emotional expression by writing improved mood states both in the depressed and nondepressed groups but induced elevation of salivary s-IgA only in the depressed group.

    Eyeblink activity was examined as a psychophysiological index of cognitive processing during a typical semantic priming task. To examine the expectancy-induced effects, the proportion of semantically related pairs was controlled. 8 undergraduates engaged in a lexical decision task for target words. Each condition differed in target type (Semantically Related with prime vs Unrelated vs Nonword) and proportion of Semantically Related pairs (High vs Low). As a result, the temporal distribution of blinks was clearly influenced by the semantic priming effect. The peak of blink bursts, which is correlated with the end of cognitive processing, occurred the fastest in the semantically Related and High proportion condition. While blink latency showed larger individual differences, the temporal distribution of blinks was suggested as a more efficient index of cognitive processing.

    The present study examined the functional association of the amygdala and right ventral prefrontal cortex (PFC) during cognitive evaluation of facial expressions. A situation was created where emotional valence of the stimuli was unconsciously manipulated by using subliminal affective priming. Twelve healthy volunteers were asked to evaluate the facial expressions of a target face (500-ms duration) such as "anger", "neutral", or "happy". All target faces expressed relatively weak anger. Just before the presentation of the target face, a prime of three conditions of 35-ms duration, angry face, neutral face, and white blank was presented. The subjects could not consciously identify the primes in this procedure. Activity in the right amygdala was greater with subliminal presentation of the angry prime compared with subliminal presentation of a neutral face or white-blank stimuli.

    The present study examined the functional association of the amygdala and right ventral prefrontal cortex (PFC) during cognitive evaluation of facial expressions. A situation was created where emotional valence of the stimuli was unconsciously manipulated by using subliminal affective priming. Twelve healthy volunteers were asked to evaluate the facial expressions of a target face (500-ms duration) such as "anger", "neutral", or "happy". All target faces expressed relatively weak anger. Just before the presentation of the target face, a prime of three conditions of 35-ms duration, angry face, neutral face, and white blank was presented. The subjects could not consciously identify the primes in this procedure. Activity in the right amygdala was greater with subliminal presentation of the angry prime compared with subliminal presentation of a neutral face or white-blank stimuli. Most importantly, the degree of activation of the right amygdala was negatively correlated with that of the right ventral PFC only with the anger prime. Furthermore, activation of the amygdala was positively correlated with rate of judgment when the subjects recognized anger in the target faces. These results are discussed in terms of the functional association between the right PFC and the amygdala and its influence on cognitive processing. © 2003 Elsevier Inc. All rights reserved.

    The amygdala in the brain can detect emotional stimuli and can evoke emotional responses to the stimuli. This study clarified, by using fMRI, that the human amugdala can detect emotional stimuli even without conscious awareness, its activation is under inhibitory control of the right ventrolateral prefrontal cortex, and its activation can predict emotional responses for the stimuli.

    効果的な森林浴プログラム及び、効果がより見込める対象者を具体的に示すことを達成する為に、本研究では、要因別の解析を行うことにより、どのような要因が、森林浴の心理効果と関連がありそうかということを2回の調査を通じて検討した。1回目は、東京大学千葉演習林で223名を対象に森林浴の前後の比較、2回目は、43名を対象に京都大学芦生研究林で森林浴をした日と森林浴をしなかった休日の心理状態の変化を比較した。測定項目は、多面的感情状態尺度、体調・気分(10cm VAS)であった。2回の調査で共通して検討した要因項目は、年齢、性別、職業、森林散策に関する嗜好、森林に行く頻度、その場所の訪問回数、同伴者の種類、日常の主観的ストレス及び健康状態、健康習慣、持病の有無、森林の滞在時間、日にち(天候)、森林浴後の疲労度(VAS)であった。また、1回目の調査にのみ用いたのは、職業性簡易ストレス調査票(精神症状、身体症状)、森林に来るまでの交通手段及び所要時間、森林内での不快なことの有無、森林散策ルート別、2回目の調査にのみ用いたのは、森林内でしたことと歩いた距離、及び、対照日の過ごし方(行ったこと、飲酒状況、運動量、好きなことができたかどうか、楽しかったかどうか)であった。1回目の調査では、森林浴により、否定的な感情の程度が低くなり、肯定的な感情の程度が上昇するということが確認され、否定的な感情に関しては、日常ストレスを感じている人ほど、その効果は大きかった。一方、2回目の調査では、森林浴日に関して、1回目の調査とは若干傾向が異なり、肯定的な感情に関しては、森林浴前後に有意差はなく、森林浴を数時間することにより良い心理効果が得られたというよりも、対照日との比較により、森林に居るだけで、肯定的な感情が高まっていたことが確認された。

    It has been argued that the selective attention characteristic of trait anxiety does not significantly influence on memory. However, attention to stimuli is considered to accelerate memory performance of the stimuli in general. The present study examined whether the selective attention due to emotional valences could reflect on recognition memory in individuals with high anxiety. In the encoding phase, a set of pairs of emotional and neutral words was presented. The duration of presentation of stimuli was manipulated in two conditions (1 300 ms vs. 2 000 ms). There was no difference in responses for stimuli between with positive and with negative valences. In the short-presentation condition, compared to the control group, the high-anxious group demonstrated greater discrimination for emotional (positive and negative) stimuli relative than for neutral ones. Their false alarm rate, on the other hand, was consistently higher than the subjects in the low-anxious group. Results in the present study suggested that selective attention that the high-anxious subjects allocated to emotional stimuli could influence performance of recognition of those stimuli.

    It has been found that an emotional stimulus such as a facial expression presented subliminally can affect subsequent information processing and behavior, usually by shifting evaluation of a subsequent stimulus to a valence congruent with the previous stimulus. This phenomenon is called subliminal affective priming. The present study was conducted to replicate and expand previous findings by investigating interaction of primes and targets in the affective priming effect. Two conditions were used, Prime (subliminal presentation 35 msec.) of an angry face of a woman and a No Prime control condition. Just after presentation of the prime, an ambiguous angry face or an emotionally neutral face was presented above the threshold of awareness (500 msec.). 12 female undergraduate women judged categories of facial expressions (Anger, Neutral, or Happiness) for the target faces. Analysis indicated that the Anger primes significantly facilitated judgment of anger for the ambiguous angry faces; however, the priming effect of the Anger primes was not observed for neutral faces. Consequently, the present finding suggested that a subliminal affective priming effect should be more prominent when affective valence of primes and targets is congruent.

    Generalized self-efficacy is considered one of important personality traits that determine psychological and physiological stress responses. The present study examined the interaction effects of generalized self-efficacy and controllability of acute stress on salivary secretory immunoglobulin A (s-IgA), task performance, and psychological stress responses in a typical learned helplessness paradigm. Twenty low and 19 high self-efficacy undergraduate women performed two response selection tasks one after another. In the first task, they were exposed to controllable or uncontrollable aversive noise. The second task was identical for all, but perceived controllability was higher for the high self-efficacy group than the low. Performance under uncontrollable condition was lower than controllable condition. The interaction of self-efficacy and controllability was observed only on the s-IgA variable; increase of secretion of s-IgA secretion under stressor uncontrollability was more prominent in the low self-efficacy group than the high. These results suggested that generalized self-efficacy was a moderator of the stressor controllability effect on secretory immunity.

    The purpose of this study was to examine the effects of listening to high-uplifting or low-uplifting music after a stressful task on (a) immune functions, (b) neuroendocrine responses, and (c) emotional states in college students. Musical selections that were evaluated as high-uplifting or low-uplifting by Japanese college students were used as musical stimuli. Eighteen Japanese subjects performed stressful tasks before they experienced each of these experimental conditions: (a) high-uplifting music, (b) low-uplifting music, and (c) silence. Subjects' emotional states, the Secretory IgA (S-IgA) level, active natural killer (NK) cell level, the numbers of T lymphocyte CD4+, CD8+, CD16+, dopamine, norepinephrine, and epinephrine levels were measured before and after each experimental condition. Results indicated low-uplifting music had a trend of increasing a sense of well-being. High-uplifting music showed trends of increasing the norepinephrine level, liveliness, and decreasing depression. Active NK cells were decreased after 20 min of silence. Results of the study were inconclusive, but high-uplifting and low-uplifting music had different effects on immune, neuroendocrine, and psychological responses. Classification of music is important to research that examines the effects of music on these responses. Recommendations for future research are discussed.

    The effects of negative air ions on computer operation were examined using a biochemical index of the activity of the sympathetic/adrenomedullary system (i.e. salivary chromogranin A-like immunoreactivity (CgA-like IR)) and a self-report questionnaire (State-Trait Anxiety Inventory, Anxiety State - STAI-S). Twelve female students carried out a word processing task for 40 min. The salivary CgA-like IR increased more than three times on the task, but the salivary cortisol did not change. The increase in the CgA-like IR level was attenuated by the exposure to negative air ions during the task. The exposure to the ions during the recovery period following the task was effective for rapidly decreasing the CgA-like IR level that had increased after the task. These effects by negative air ions were also observed using STAI-S. Task performance was slightly but significantly improved by the presence of negative air ions. These results suggest that negative air ions are effective for the reduction of and the prompt recovery from stress caused by computer operation. © 2002 Elsevier Science B.V. All rights reserved.

    The effects of negative air ions on computer operation were examined using a biochemical index of the activity of the sympathetic/adrenoniedullary system (i.e. salivary chromogranin A-like immumoreactivity (CgA-like IR)) and a self-report questionnaire (State-Trait Anxiety Inventory, Anxiety State-STAI-S). Twelve female students carried out a word processing task for 40 min. The salivary CgA-like IR increased more than three times on the task, but the salivary cortisol did not change. The increase in the CgA-like IR level was attenuated by the exposure to negative air ions during the task. The exposure to the ions during the recovery period following the task was effective for rapidly decreasing the CgA-like IR level that had increased after the task. These effects by negative air ions were also observed using STAI-S. Task performance was slightly but significantly improved by the presence of negative air ions. These results suggest that negative air ions are effective for the reduction of and the prompt recovery from stress caused by computer operation. (C) 2002 Elsevier Science B.V. All rights reserved.

    The authors report four cases in which severely damaged human remains were identified by mitochondrial DNA (mtDNA) sequencing. Degraded DNA was extracted from highly adipoceratous tissues using the phenol-chloroform method and polymerase chain reaction amplified for sequencing of two hypervariable regions, hypervariable region 1 and hypervariable region 2, of mitochondrial DNA. They also sequenced these regions of blood samples that were obtained from the presumptive mother or sister of the human remains. The sequencing results were compared with each other and with the Anderson's sequence. It was concluded from the sequence data that a lower part of a body in case 1 and some organs in case 2 were from the same woman, and a human head in case 3 and a female body in case 4 were from the relative of a presumptive mother and a sister, respectively.

    This article presents findings of a laboratory experiment on the association of the Type A behavior pattern with reactivity of secretory immune functioning to brief stress. 38 female undergraduate students classified as Type A (n=19) or as Type B (n=19) on the basis of their scores on the Kwansei Gakuin Type ii scale performed a continuous arithmetic task in a situation in which they were exposed to aversive loud noise. Secretory immunoglobulin A (s-IgA) in saliva and autonomic measures (heart rate and frequency of eyeblink) were evaluated before and after the manipulation of stress. The volume of s-IgA at baseline was significantly higher for the Type A group than for the Type B group, suggesting that the former relative to the latter might be chronically higher in mucosal immune functioning. Also, the volume of s-IgA significantly increased after exposure to a brief stress for the Type B group bur did not change for the Type A group, a finding which might indicate that the Type A group may have less immune reactivity to a brief stress.

    Japanese college students viewed a series of positive and negative stimulus words printed in katakana, a Japanese syllabary. Jacoby's process-dissociation procedure was wed to assess the roles of conscious and unconscious processes in stimulus recognition. There was a stronger conscious recollective component in recognition of negative items and a higher correct rejection rate for negative stimuli, replicating American findings reported by Robinson-Riegler and Winton, and Ortony, Turner and Antos. In addition, during the encoding phase, negative stimuli were associated with more eyeblinks and longer eyeblink latencies than positive stimuli; this pattern suggests greater cognitive activity in response to negative stimuli, consonant with Taylor's mobilization-minimization hypothesis. The eyeblink response, as measured in the present research, represents a new method for assessing the positive-negative asymmetries that are characteristic of the mobilization process.

    Introduction: Several modalities of catheter ablation have been proposed to eliminate Mahaim pathway conduction. However, limited research has been reported on the electrophysiologic nature of this pathway in its entity. Methods and Results: In seven patients, electrophysiologic study was performed, and radiofrequency energy was applied to investigate the electrophysiologic clues for successful ablation. In all seven patients, the Mahaim pathway was diagnosed as a right-sided atriofascicular or atrioventricular pathway with decremental properties. In two patients, two different kinds of electrograms were recorded through the ablation catheter positioned at the Mahaim pathway location: one was suggestive of conduction over the decremental portion, demonstrating a dulled potential; and the other of nondecremental conduction, demonstrating a spiked potential. All but one of the Mahaim pathways were eliminated successfully at the atrial origin where the spiked Mahaim potential was recorded. Radiofrequency energy application was performed at the slow potential site resulting in failure to eliminate the conduction over the Mahaim pathway. Conduction block at the site between the slow and fast potential recording sites was provoked by intravenous administration of adenosine, concomitant with a decrease in the amplitude of the Mahaim potential. In one patient, the clinical arrhythmia was a sustained monomorphic ventricular tachycardia originating from the ventricular end of the Mahaim fiber. Conclusion: The identification of Mahaim spiked potentials may be the optimal method to permit their successful ablation. Detailed electrophysiologic assessment is indispensable for successful ablation of tachycardias associated with Mahaim fibers because tachycardias unassociated with Mahaim fibers can occur despite complete elimination of the Mahaim fiber.

    Eyeblink activity was examined based on a discrete-trial paradigm in which 17 subjects engaged in a semantic priming task. They were presented a series of pairs of words (prime and target) associatively related or associatively unrelated and were required to name them as quickly as possible. Cognitive load or difficulty of naming of the target word was also manipulated. The latency data for naming of the target word showed a typical priming effect, namely, facilitation of naming speed by the associatively related prime word. The eyeblink rate changed synchronically to onset of stimuli as a function of prime-target relationship and cognitive load during the task. Specifically, the eyeblink rate was suppressed during presentation of the target word and peaked just after that. This study showed that suppression of eyeblinks was longer on trials with high cognitive loads than on those with low cognitive loads and the peak of eyeblink rate was higher on trials for which the prime and target were unrelated than on those for which they were related. These results suggested that the eyeblink activity is influenced by inner cognitive processes of word recognition.

    The purpose of the present study was to examine the erects of the physiological arousal and the priorsubconscious processing of hostility-related words upon the cognitive complexity in person perception. First, sixteen male and 16 female college students performed a cognitive task in which they processed hostility-related words or neutral words unconsciously in a high arousal or a normal arousal state. In the second ostensibly unrelated task, the subjects were presented with an ambiguous description of target person's mild hostile behavior and they were asked to rate the impression of the target person on several SD-trait scales. It was found that the higher the subjects' arousal level was, the simpler the cognitive complexity became. Also, when the subjects processed neutral words in the high arousal state, individual differences of the impression were the largest. The effects of hostility-related words to decrease the individual differences in the high arousal state, however, were not found. These results indicate that physiological arousal may have an important role in the mechanisms of social cognition.

    Two experiments were conducted to examine effects of facial expressions upon social cognitive processes in which the impression of another person is formed. In each experiment, 30 female college students were induced to display or conceal their facial reactions to a hypothetical target person whose behaviors were mildly hostile (Exp. 1) or mildly friendly (Exp. 2), or their facial expressions were not manipulated. Displaying the facial expressions shifted the impression into the congruent directions with hedonic values corresponding to the facial expressions. Concealing the facial expressions, however, did not influence impression formation. Also, the positive-negative asymmetry was observed in the facial feedback effects, that is, the negative facial expression had a stronger effect on social cognition than the positive one.

    An experiment was conducted to examine the mediating role of physiological arousal in social facilitation. It was hypothesized that the elevation of arousal level by the presence of other persons or evaluative apprehension would facilitate task performance. Twenty-four male and 24 female college students performed simple task alone, with a cooperative person, or with a competitive person. One half of the subjects was given an instruction which would produce evaluative apprehension. Subjects' skin potential responses were measured as the indices of physiological arousal. Although the hypothesis was supported by the analysis of psycho-physiological index, but it was not at all by the self-reported index of arousal.

  12. Brain functions modulating redistribution of natural killer cells accompanying cognitive appraisal of acute stress

    Ohira H.( 担当: 単著)

    Social Neuroscience and Public Health: Foundations for the Science of Chronic Disease Prevention  2013年1月  ( ISBN:9781461468516

    記述言語:日本語

    Acute stress increases the number of natural killer (NK) cells, which plays a critical role in innate immunity, in peripheral circulation within several minutes. This phenomenon is called redistribution of NK cells and has been thought to reflect facilitation of preventive defense. Redistribution of NK cells is not a stereotyped response but is sensitive to cognitive appraisals of stressors, and thus might be under control by the brain. We have explored neural mechanisms of the top-down modulation of NK cell distribution by the brain using simultaneous measurement of brain activity by positron emission tomography and the number of NK cells in blood during cognitive acute stress tasks where stressor controllability and cognitive flexibility were manipulated. Results suggested that the dorsolateral prefrontal and orbitofrontal cortices might be involved in appraisals of stressors, and modulate NK cell redistribution via the anterior cingulate cortex and the vagus nerve.

    Reconciliation is an integral part of our social lives. Nevertheless, if a victim perceives the risk of further exploitation by his/her transgressor as non-negligible, the victim may well have difficulty forgiving the transgressor. Therefore, a key ingredient of reconciliation is the transgressor's sincere apology. Theoretical and empirical studies have shown that transgressors can make their apologies credible by incurring a substantial cost. Therefore, we hypothesized that costly apologies, compared to non-costly apologies (i.e., simply saying “sorry”), would effectively communicate a transgressor's conciliatory intention. In a functional magnetic resonance imaging (fMRI) study, participants were asked to imagine a friend committing a mild interpersonal transgression (e.g., standing up the participant) and then apologizing in a costly fashion, apologizing in a non-costly fashion, or not apologizing at all. Compared to non-costly apologies and non-apologies, costly apologies (signals of conciliatory intention) more strongly activated the theory-of-mind network (i.e., bilateral temporoparietal junction, precuneus, medial prefrontal cortex). Moreover, we did not observe any significant differences in brain responses to non-costly apologies and non-apology controls. These results underscore the importance of costly signals in human communication and in human peace-making in particular.

    Previous studies have reported that the concealed information test (CIT) is a reliable and powerful method for detecting information. However, the external validity of the CIT studies has not been fully proven. In particular, few studies have examined the effects of emotional arousal at memory encoding on physiological responses in the CIT. The present study investigated the influence on the CIT of the magnitude of emotional arousal at memory encoding of a mock crime, using the P300 component of the event-related brain potential (ERP). In accord with the assumptions of excitation-transfer theory, we presented emotionally arousing pictures before a mock crime. Participants were randomly assigned to either a high emotional arousal group (n = 10) or a low emotional arousal group (n = 11), viewing pictures expected to arouse emotion at a high or low level, respectively. Subsequently, all participants enacted the same mock crime, in which they were instructed to stab a pillow with a sharp-edged tool (e.g., a kitchen knife or ice pick) as if harassing a mannequin lying on a bed. After the antecedent emotional experience, the P300-based CIT was conducted. Participants in the high arousal group showed significantly greater P300 amplitudes in response to a probe stimulus compared with the low arousal group. No differences were found between the groups in response to irrelevant stimuli. These results support the notion that emotional arousal influences the P300 in the CIT paradigm.

    Happiness is regarded as one of the most fundamental human goals. Given recent reports that positive feelings are contagious (e.g., the presence of a happy person enhances others' happiness) because of the human ability to empathize (i.e., sharing emotions), empathic ability may be a key factor in increasing one's own subjective level of happiness. Based on previous studies indicating that a single nucleotide polymorphism in the serotonin 2A receptor gene [HTR2A rs6311 guanine (G) vs. adenine (A)] is associated with sensitivity to emotional stimuli and several mental disorders such as depression, we predicted that the polymorphism might be associated with the effect of sharing happiness. To elucidate the neural and genetic correlates of the effect of sharing happiness, we first performed functional magnetic resonance imaging (fMRI) during a "happy feelings" evocation task (emotional event imagination task), during which we manipulated the valence of the imagined event (positive, neutral, or negative), as well as the presence of a friend experiencing a positive-valence event (presence or absence). We recruited young adult women for this fMRI study because empathic ability may be higher in women than in men. Participants felt happier (p &lt; 0.01) and the mentalizing/ theory-of-mind network, which spans the medial prefrontal cortex, temporoparietal junction, temporal poles, and precuneus, was significantly more active (p &lt; 0.05) in the presence condition than in the absence condition regardless of event valence. Moreover, participants with the GG (p &lt; 0.01) and AG (p &lt; 0.05) genotypes of HTR2A experienced happier feelings as well as greater activation of a part of the mentalizing/ theory-of-mind network (p &lt; 0.05) during empathy for happiness (neutral/presence condition) than those with the AA genotype. In a follow-up study with a vignette-based questionnaire conducted in a relatively large sample, male and female participants were presented with the same imagined events wherein their valence and the presence of a friend were manipulated. Results showed genetic differences in happiness-related empathy regardless of sex (p &lt; 0.05). Findings suggest that HTR2A polymorphisms are associated with the effect of sharing happiness by modulating the activity of the mentalizing/ theory-of-mind network.

    Psychopathy is a group of personality traits that are associated with violations of social norms. Previous studies have suggested that people with psychopathic traits in subclinical populations do not necessarily display antisocial, self-defeating behaviors, and instead may strategically show adaptive behaviors in response to cues during reciprocal social interactions. Therefore, in the present study, we examined whether the association between psychopathic traits and unfair behavior can be moderated by a potential for punishment and social distance (anonymity), which are known to facilitate fair behavior. We focused on two psychopathic traits: primary and secondary psychopathy. Primary psychopathy is characterized by callousness, shallow affect, manipulation, and superficial charm. In contrast, secondary psychopathy is associated with impulsivity and lack of long-term goals, and is related to hostile behavior. A total of 348 undergraduate students determined the amounts of money that they would offer to strangers or friends at their university in hypothetical scenarios of the ultimatum game (UG) and the dictator game (DG). While gender affected decisions in the hypothetical scenarios of the DG, it did not interact with psychopathic traits. The score for primary psychopathy on the Levenson self-report psychopathy scale predicted unfair monetary offers to strangers in the DG, where participants could not be punished. However, compared with their offers in the DG, individuals with higher scores for primary psychopathy made larger offers in the UG, where low offers could trigger punishment from the recipient. Moreover, primary psychopathy did not decrease the amounts of offers in either game when the participant considered the recipient to be a friend. On the other hand, secondary psychopathy was not associated with differences in behavioral fairness depending on a potential for punishment or social distance. Based on these findings, we discuss strategic social skills as a function of primary psychopathy.

    A broadly used computational framework posits that two learning systems operate in parallel during the learning of choice preferences-namely, the model-free and model-based reinforcement-learning systems. In this study, we examined another possibility, through which model-free learning is the basic system and model-based information is its modulator. Accordingly, we proposed several modified versions of a temporal-difference learning model to explain the choice-learning process. Using the two-stage decision task developed by Daw, Gershman, Seymour, Dayan, and Dolan (2011), we compared their original computational model, which assumes a parallel learning process, and our proposed models, which assume a sequential learning process. Choice data from 23 participants showed a better fit with the proposed models. More specifically, the proposed eligibility adjustment model, which assumes that the environmental model can weight the degree of the eligibility trace, can explain choices better under both model-free and model-based controls and has a simpler computational algorithm than the original model. In addition, the forgetting learning model and its variation, which assume changes in the values of unchosen actions, substantially improved the fits to the data. Overall, we show that a hybrid computational model best fits the data. The parameters used in this model succeed in capturing individual tendencies with respect to both model use in learning and exploration behavior. This computational model provides novel insights into learning with interacting model-free and model-based components.

    Although previous studies have revealed the role of oxytocin (OT) in parental behavior, the role of OT has not been investigated through the direct assessment of prefrontal brain activation during parenting. By using functional near-infrared spectroscopy, we aimed to show the relationship between parental [maternal (N = 15) and paternal (N = 21)] OT levels and the activation of the prefrontal cortex (PFC), while holding their infants after separation. Baseline OT levels were measured in the subjects' saliva samples before the experiment. Prefrontal brain activation was assessed in participants sitting alone on a chair (i.e., separation from their infant for 120 s) and during the target period (i.e., holding their infant for 45 s), which was done in triplicate. The oxygen hemoglobin (oxy-Hb) dissociation curve significantly increased in 9 out of 22 channels on the PFC when maternal and paternal samples were combined. However, only the fathers showed a correlation between salivary OT and oxy-Hb signal. Furthermore, while holding their infants, high-OT fathers showed left hemispheric dominance compared to low-OT fathers, while high-OT mothers showed right hemispheric dominance compared to low-OT mothers. This study showed that fathers with high-OT levels showed neural activation with left hemispheric dominance, while holding their infants, suggesting that increase of OT level might activate paternal PFC related to parenting behavior, although the same is not true for mothers.

    This study investigates the prolonged effects of physiological responses induced by acute stress on risk-taking in decision-making. Participants were divided into a Stress group (N = 14) and a Control group (N = 12). The Trier Social Stress Test was administered as an acute stressor, and reading was administered as a control task; thereafter, participants performed a decision-making task in which they needed to choose a sure option or a gamble option in Gain and Loss frame trials 2 h after (non-) exposure to the stressor. Increased cortisol, adrenaline, heart rate (HR), and subjective stress levels validated acute stress manipulation. Stressed participants made fewer risky choices only in the Gain domain, whereas no effect of stress was shown in the Loss domain. Deceleration of HR reflecting attention was greater for Gains compared with Losses only in the Stress group. Risk avoidance was determined by increased levels of cortisol caused by acute stress. These results suggest that processes regarding glucocorticoid might be involved in the prolonged effects of acute stress on the evaluation of risks and the monitoring of outcomes in decision-making.

    A bad reputation can persistently affect judgments of an individual even when it turns out to be invalid and ought to be disregarded. Such indelible distrust may reflect that the negative evaluation elicited by a bad reputation transfers to a person. Consequently, the person him/herself may come to activate this negative evaluation irrespective of the accuracy of the reputation. If this theoretical model is correct, an evaluation-related brain region will be activated when witnessing a person whose bad reputation one has learned about, regardless of whether the reputation is deemed valid or not. Here, we tested this neural hypothesis with functional magnetic resonance imaging (fMRI). Participants memorized faces paired with either a good or a bad reputation. Next, they viewed the faces alone and inferred whether each person was likely to cooperate, first while retrieving the reputations, and then while trying to disregard them as false. A region of the left ventrolateral prefrontal cortex (vIPFC), which may be involved in negative evaluation, was activated by faces previously paired with bad reputations, irrespective of whether participants attempted to retrieve or disregard these reputations. Furthermore, participants showing greater activity of the left ventrolateral prefrontal region in response to the faces with bad reputations were more likely to infer that these individuals would not cooperate. Thus, once associated with a bad reputation, a person may elicit evaluation related brain responses on their own, thereby evoking distrust independently of their reputation.

    Cytokines are important mediators of various stress-related modulations of immune function. A major genetic factor determining inter-individual differences in stress reactivity is polymorphisms of the serotonin (5-hydroxytryptamine, 5HT) transporter (5HTT) gene. A short (S) variant, compared with a long (L) variant, of the promoter region of the 5HTT gene-linked polymorphic region (5HTTLPR) has been related to emotional and stress hyper-reactivity. The present study examined whether the 5HTTLPR can modulate responses of inflammatory cytokines under acute stress. Nine Japanese male participants carrying two copies of the S alleles and nine Japanese males carrying S and L alleles underwent the Trier Social Stress Test (TSST). Inflammatory cytokines, endocrine parameters, heart rate and subjective stress were measured before, during and after the task. The participants carrying the SS alleles, but not those carrying the SL alleles, showed a significant increase of IL-1 beta immediately after TSST. This hyper-reactivity to acute stress in individuals with the SS alleles was also observed in their heart rate and cortisol levels. These results suggest that the S allele of the 5HTTLPR is consistently associated with stress reactivity in multi-level stress-related biological systems.

    Patients suffering from neuropsychiatric disorders such as substance-related and addictive disorders exhibit altered decision-making patterns, which may be associated with their behavioral abnormalities. However, the neuronal mechanisms underlying such impairments are largely unknown. Using a gambling test, we demonstrated that methamphetamine (METH)-treated rats chose a high-risk/high-reward option more frequently and assigned higher value to high returns than control rats, suggestive of changes in decision-making choice strategy. Immunohistochemical analysis following the gambling test revealed aberrant activation of the insular cortex (INS) and nucleus accumbens in METH-treated animals. Pharmacological studies, together with in vivo microdialysis, showed that the insular neural system played a crucial role in decision-making. Moreover, manipulation of INS activation using designer receptor exclusively activated by designer drug technology resulted in alterations to decision-making. Our findings suggest that the INS is a critical region involved in decision-making and that insular neural dysfunction results in risk-taking behaviors associated with altered decision-making.

    Feedback-related negativity (FRN) is an event-related brain potential (ERP) component elicited by errors and negative outcomes. Previous studies proposed that FRN reflects the activity of a general error-processing system that incorporates reward prediction error (RPE). However, other studies reported inconsistent results on this issue - namely, that FRN only reflects the valence of feedback and that the magnitude of RPE is reflected by the other ERP component called P300. The present study focused on the relationship between the FRN amplitude and RPE. ERPs were recorded during a reversal learning task performed by the participants, and a computational model was used to estimate trial-by-trial RPEs, which we correlated with the ERPs. The results indicated that FRN and P300 reflected the magnitude of RPE in negative outcomes and positive outcomes, respectively. In addition, the correlation between RPE and the P300 amplitude was stronger than the correlation between RPE and the FRN amplitude. These differences in the correlation between ERP and RPE components may explain the inconsistent results reported by previous studies; the asymmetry in the correlations might make it difficult to detect the effect of the RPE magnitude on the FRN and makes it appear that the FRN only reflects the valence of feedback.

    We analyzed skin conductance response (SCR) as a psychophysiological index to evaluate affective aspects of consumer preferences for cosmetic products. To examine the test-retest reliability of association between preferences and SCR, we asked 33 female volunteers to complete two experimental sessions approximately 1 year apart. The participants indicated their preferences in a typical paired comparison task by choosing the better option from a combination of two products among four products. We measured anticipatory SCR prior to expressions of the preferences. We found that the mean amplitude of the SCR elicited by the preferred products was significantly larger than that elicited by the non-preferred products. The participants' preferences and corresponding SCR patterns were well preserved at the second session 1 year later. Our results supported cumulating findings that SCR is a useful index of consumer preferences that has future potential, both in laboratory and marketing settings.

    We previously reported that sympathetic activity was associated with exploration in decision-making indexed by entropy, which is a concept in information theory and indexes randomness of choices or the degree of deviation from sticking to recent experiences of gains and losses, and that activation of the anterior insula mediated this association. The current study aims to replicate and to expand these findings in a situation where contingency between options and outcomes is manipulated. Sixteen participants performed a stochastic decision-making task in which we manipulated a condition with low uncertainty of gain/loss (contingent-reward condition) and a condition with high uncertainty of gain/loss (random-reward condition). Regional cerebral blood flow was measured by 150-water positron emission tomography (PET), and cardiovascular parameters and catecholamine in the peripheral blood were measured, during the task. In the contingent-reward condition, norepinephrine as an index of sympathetic activity was positively correlated with entropy indicating exploration in decision-making. Norepinephrine was negatively correlated with neural activity in the right posterior insula, rostral anterior cingulate cortex, and dorsal pons, suggesting neural bases for detecting changes of bodily states. Furthermore, right anterior insular activity was negatively correlated with entropy, suggesting influences on exploration in decision-making. By contrast, in the random-reward condition, entropy correlated with activity in the dorsolateral prefrontal and parietal cortices but not with sympathetic activity. These findings suggest that influences of sympathetic activity on exploration in decision-making and its underlying neural mechanisms might be dependent on the degree of uncertainty of situations.

    Humans are capable of correcting their actions based on actions performed in the past, and this ability enables them to adapt to a changing environment. The computational field of reinforcement learning (RL) has provided a powerful explanation for understanding such processes. Recently, the dual learning system, modeled as a hybrid model that incorporates value update based on reward-prediction error and learning rate modulation based on the surprise signal, has gained attention as a model for explaining various neural signals. However, the functional significance of the hybrid model has not been established. In the present study, we used computer simulation in a reversal learning task to address functional significance in a probabilistic reversal learning task. The hybrid model was found to perform better than the standard RL model in a large parameter setting. These results suggest that the hybrid model is more robust against the mistuning of parameters compared with the standard RL model when decision-makers continue to learn stimulus-reward contingencies, which can create abrupt changes. The parameter fitting results also indicated that the hybrid model fit better than the standard RL model for more than 50% of the participants, which suggests that the hybrid model has more explanatory power for the behavioral data than the standard RL model.

    Happiness has been viewed as a temporary emotional state (e. g., pleasure) and a relatively stable state of being happy (subjective happiness level). As previous studies demonstrated that individuals with high subjective happiness level rated their current affective states more positively when they experience positive events, these two aspects of happiness are interrelated. According to a recent neuroimaging study, the cytosine to thymine single-nucleotide polymorphism of the human cannabinoid receptor 1 gene is associated with sensitivity to positive emotional stimuli. Thus, we hypothesized that our genetic traits, such as the human cannabinoid receptor 1 genotypes, are closely related to the two aspects of happiness. In Experiment 1, 198 healthy volunteers were used to compare the subjective happiness level between cytosine allele carriers and thymine-thymine carriers of the human cannabinoid receptor 1 gene. In Experiment 2, we used positron emission tomography with 20 healthy participants to compare the brain responses to positive emotional stimuli of cytosine allele carriers to that of thymine-thymine carriers. Compared to thymine-thymine carriers, cytosine allele carriers have a higher subjective happiness level. Regression analysis indicated that the cytosine allele is significantly associated with subjective happiness level. The positive mood after watching a positive film was significantly higher for the cytosine allele carriers compared to the thymine-thymine carriers. Positive emotion-related brain region such as the medial prefrontal cortex was significantly activated when the cytosine allele carriers watched the positive film compared to the thyminethymine carriers. Thus, the human cannabinoid receptor 1 genotypes are closely related to two aspects of happiness. Compared to thymine-thymine carriers, the cytosine allele carriers of the human cannabinoid receptor 1 gene, who are sensitive to positive emotional stimuli, exhibited greater magnitude positive emotions when they experienced positive events and had a higher subjective happiness level.

    The somatic marker hypothesis asserts that decision-making can be guided by feedback of bodily states to the brain. In line with this hypothesis, the present study tested whether sympathetic activity shows an association with a tonic dimension of decision-making, exploratory tendency represented by entropy in information theory, and further examined the neural mechanisms of the association. Twenty participants performed a stochastic reversal learning task that required decision-making in an unstable and uncertain situation. Regional cerebral blood flow was evaluated using 15O-water positron emission tomography (PET), and cardiovascular indices and concentrations of catecholamine in peripheral blood were also measured, during the task. In reversal learning, increased epinephrine during the task positively correlated with larger entropy, indicating a greater tendency for exploration in decision-making. The increase of epinephrine also correlated with brain activity revealed by PET in the somatosensory cortices, anterior insula, dorsal anterior cingulate cortex, and the dorsal pons. This result is consistent with previously reported brain matrixes of representation of bodily states and interoception. In addition, activity of the anterior insula specifically correlated with entropy, suggesting possible mediation of this brain region between peripheral sympathetic arousal and exploration in decision-making. These findings shed a new light about a role of bodily states in decision-making and underlying neural mechanisms. © 2013 IBRO.

    The phenomenon in which a certain smell evokes a specific memory is known as the Proust phenomenon. Odor-evoked autobiographic memories are more emotional than those elicited by other sensory stimuli. The results of our previous study indicated that odor-evoked autobiographic memory accompanied by positive emotions has remarkable effects on various psychological and physiological activities, including the secretion of cytokines, which are immune-signaling molecules that modulate systemic inflammation. In this study, we aimed to clarify the neural substrates associated with the interaction between odor-evoked autobiographic memory and peripheral circulating cytokines. We recruited healthy male and female volunteers and investigated the association between brain responses and the concentration of several cytokines in the plasma by using positron emission tomography (PET) recordings when an autographic memory was evoked in participants by asking them to smell an odor that was nostalgic to them. Participants experienced positive emotions and autobiographic memories when nostalgic odors were presented to them. The levels of peripheral proinflammatory cytokines, such as the tumor necrosis factor-alpha (TNF-alpha) and interferon-gamma (IFN-gamma), were significantly reduced after experiencing odor-evoked autobiographic memory. Subtraction analysis of PET images indicated that the medial orbitofrontal cortex (mOFC) and precuneus/posterior cingulate cortex (PCC) were significantly activated during experiences of odor-evoked autobiographic memory. Furthermore, a correlation analysis indicated that activities of the mOFC and precuneus/PCC were negatively correlated with IFN-gamma concentration. These results indicate that the neural networks including the precuneus/PCC and mOFC might regulate the secretion of peripheral proinflammatory cytokines during the experience of odor-evoked autobiographic memories accompanied with positive emotions.

    We investigated whether vagal tone, as assessed by heart rate variability (HRV), moderates the neural correlates of immune and physiological responses to acute stress. Participants with low and high baseline HRV underwent a reversal learning task as an acute stressor. Natural killer cells, norepinephrine, and adrenocorticotropic hormone in peripheral blood changed with acute stress in the high HRV group only. Activity in the prefrontal cortex and striatum correlated with the immune and physiological indices in the high HRV group. High vagal tone may reflect more flexible top-down brain regulation of immune and physiological activity. (C) 2013 Elsevier B.V. All rights reserved.

    The present study was performed to investigate the associations between eye-blink behaviors and various other factors in primates. We video-recorded 141 individuals across 71 primate species and analyzed the blink rate, blink duration, and "isolated'' blink ratio (i.e., blinks without eye or head movement) in relation to activity rhythms, habitat types, group size, and body size factors. The results showed close relationships between three types of eye-blink measures and body size factors. All of these measures increased as a function of body weight. In addition, diurnal primates showed more blinks than nocturnal species even after controlling for body size factors. The most important findings were the relationships between eye-blink behaviors and social factors, e.g., group size. Among diurnal primates, only the blink rate was significantly correlated even after controlling for body size factors. The blink rate increased as the group size increased. Enlargement of the neocortex is strongly correlated with group size in primate species and considered strong evidence for the social brain hypothesis. Our results suggest that spontaneous eye-blinks have acquired a role in social communication, similar to grooming, to adapt to complex social living during primate evolution.

    OBJECTIVES: This study aimed to examine one of biological correlates, pro-inflammatory cytokine, in rejection of unfair financial offers in the Ultimatum Game (UG), where the division of a sum of money is proposed and the player can accept or reject this offer.
    METHODS: Nineteen participants played 20 trials of the UG as responders, and they were proposed unfair offers in a half of the trials. Baseline levels of several pro-inflammatory and anti-inflammatory cytokines, subjective happiness, and depression of them were measured.
    RESULTS: Participants with higher levels of the pro-inflammatory cytokine, interleukin (IL)-6 rejected fewer unfair offers. This effect of IL-6 levels on decision-making was independent from other pro-inflammatory cytokines, anti-inflammatory cytokines, subjective happiness, and depression.
    CONCLUSIONS: These results suggested that chronic higher levels of IL-6 might affect functions of neural regions related to decision making, and thus can modulate rejection of unfair offers.

    Mindfulness is currently attracting a great deal of attention as a psychotherapy technique. It is defined as bringing one's complete attention to the experiences occurring in the present moment in a nonjudgmental or accepting way. The Five Facet Mindfulness Questionnaire (FFMQ) was developed to assess individual differences in mindfulness states. The FFMQ is composed of five facets representing elements of mindfulness: non-reactivity to inner experience, non-judging, acting with awareness, describing, and observing. In the present study, we applied voxel-based morphometry to investigate the relationship between the brain structure and each facet as measured by the FFMQ. The results showed a positive association between the describing facet of mindfulness on the FFMQ and gray matter volume in the right anterior insula and the right amygdala. In conclusion, mindfulness was related with development in parts of the somatic marker circuit of the brain.

    Animal studies have revealed that chronic stress shifts cognitive strategies from the flexible goal-directed action to the simple and rigid habit action. In addition, stress-induced atrophy in the prefrontal cortex and dorsomedial striatum which are involved in the goal-directed action and hypertrophy of the dorsolateral striatum which is critical for the habit action were parallel with the effects of chronic stress on behaviors. The present study tested whether these previous findings in animal studies are compatible in humans by analyzing effects of chronic stress on neural and cardiovascular responses, which are likely important for performing appropriate actions. Twenty healthy men exposed to low or high chronic job stress performed a stochastic reversal learning task, which required cognitive flexibility and the goal-directed action. Regional cerebral blood flow was evaluated during the task using (15)O-water positron emission tomography, and cardiovascular parameters such as blood pressure and heart rate were also measured. During the reversal learning task, whereas participants with low chronic job stress exhibited activity in the anterior caudate, as well as orbitofrontal cortex, ventrolateral prefrontal cortex, insula, and midbrain, which might be related to the goal-directed action, participants with high chronic job stress exhibited no activity in such brain regions. Furthermore, participants with high chronic job stress exhibited less reactivity in diastolic blood pressure, which might be mediated by anterior cingulate cortical activity. These findings, in line with previous studies, suggested that chronic job stress correlates with less activity in brain regions related to the goal-directed action, and insensitive physiological responses in humans.

    To maintain our well-ordered social life, we should detect whether a behavior is immoral. In this study, we tried to reveal the plural cognitive processes involved in the moral judgment, using EEG with high temporal resolution. As stimuli, one sentence consisted of three phrases (in Japanese) was used per trial. The predicate was modified to create behavior variations for four conditions: Moral&amp;frasl;Violation (e.g., He pockets a coin picked up.), Moral&amp;frasl;Match (He hands over a coin picked up.), Semantic&amp;frasl;Violation (He empathizes a coin picked up.), Semantic&amp;frasl;Match (He looks a coin picked up.). We compared ERP responses between violation and match sentences, and demonstrated that N400 component in Semantic&amp;frasl;Violation was larger than in Semantic&amp;frasl;Match. For moral sentences, N400 was not significantly different between violation and match, while LPC in Moral&amp;frasl;Violation was larger than in Moral&amp;frasl;Match. This suggested that the cognition of moral violation is more complex cognitive process compared with semantic violation.

    Life choices (e.g., occupational choice) often include situations with two or more possible correct answers, thereby putting us in a situation of conflict. Recent reports have described that the evaluation of conflict might be crucially mediated by neural activity in the dorsal anterior cingulate cortex (dACC), although the reduction of conflict might rather be associated with neural activity in the medial prefrontal cortex (MPFC). What remains unclear is whether these regions mutually interact, thereby raising the question of their functional connectivity during conflict situations. Using psychophysiological interaction (PPI) analyses of functional magnetic resonance imaging (fMRI) data, this study shows that the dACC co-varied significantly higher with the MPFC during an occupational choice task with two possible correct answers when compared to the control task: a word-length task with one possible correct answer. These results suggest that the MPFC has a functional relation with dACC, especially in conflict situations where there is no objective correct answer. Taken together, this lends support to the assumption that the MPFC might be crucial in biasing the decision, thereby reducing conflict. (C) 2010 Elsevier Ireland Ltd. All rights reserved.

    This review summarizes empirical findings that have shown affective deficits of psychopathy. Previous studies have accounted for a failure of moral socialization in individuals with psychopathy in terms of low levels of fearfulness and empathy that may lead to an attenuated ability to inhibit deviant behaviors in response to punishments and distress cues from others. Both low-fear and low-empathy hypotheses have implied that a neural basis of psychopathy is a dysfunction of amygdala, a brain region of the center in affective processing. However, the affective dysfunction of psychopathy can also be associated with adaptive behaviors to maximize gains and minimize losses in some situations. Hence, we propose that psychopathy is one side of humans to shape a selfish strategy if necessary.

    The authors investigated whether self-knowledge has a function to reduce conflict by biasing one of two choices during occupational choice (e.g., Which occupation do you think you could do better-dancer or chemist). In the three experiments, event-related brain potentials were recorded. Experiment I revealed that the amplitude of the conflict-related negativity (CRN) reflects strength of conflict during occupational choice. Results of Experiment 2 demonstrated that the CRN amplitude during occupational choice was smaller when self-knowledge was activated than when other-knowledge was activated. Experiment 3 showed that the CRN amplitude during occupational choice was decreased more when self-knowledge that biases one choice of occupation was activated than when self-knowledge that does not bias was activated. These results suggest that self-knowledge reduces conflict by biasing one of multiple choices in situations where two or more possible correct answers can be given.

    Limbic system activation that occurs when a person experiences several emotions is primarily represented by the amygdala output that influences autonomic brainstem nuclei that control autonomic nervous function, thus modulating the endocrine and immune systems. Amygdala activity is modulated by the serotonin transporter gene-linked polymorphic region (5HTTLPR); however, whether variations in 5HTTLPR influence central nervous and immune activities in response to positive stimuli remains unclear. Here, we found that seeing a favorite person induced significantly higher amygdala activity in individuals with the 5HTTLPR SS genotype than in others. This activity was positively correlated with changes in the NK cell proportion among peripheral lymphocytes. Thus, 5HTTLPR influences attraction and the associated interactions between the central nervous and immune systems in affectively positive situations. (C) 2009 Elsevier Ireland Ltd.

    To examine the functional association between brain and autonomic activities accompanying decision-making, we simultaneously recorded regional cerebral blood flow using (15)O-water positron emission tomography and event-related brain potentials (ERPs) time-locked to feedback of reward and punishment, as well as cardiovascular parameters, during a stochastic decision-making task. We manipulated the uncertainty Of Outcomes in the task; specifically, we compared a condition with high predictability of reward/punishment (contingent-reward condition) and a condition with low predictability of reward/punishment (random-reward condition). The anterior cingulate cortex (ACC) was commonly activated in both conditions. Compared with the contingent-reward condition, the orbitofrontal and right dorsolateral prefrontal cortices and dorsal striatum were activated in the random-reward condition, where subjects had to continue to seek contingency between stimuli and reward/punishment. Activation of these brain regions correlated with a positive component of ERPs locked to feedback signals (feedback-related positivity), which showed an association with behavioral decision-making in the contingent-reward condition. Furthermore, cardiovascular responses were attenuated in the random-reward condition, where continuous attention and contingency monitoring were needed, and such attenuation of cardiovascular responses was mediated by vagal activity that was governed by the rostral ACC. These findings suggest that the prefrontal-striatal network provides a neural basis for decision-making and modulation over the peripheral autonomic activity accompanying decision-making.

    Life choice (e.g. occupation choice) often includes situations with two or more possible answers. How does the brain respond to such conflict-ridden situations? We investigated whether the dorsal anterior cingulate cortex (dACC) evaluates the degree of conflict between possible answers. Additionally, we investigated whether the medial prefrontal cortex (MPFC) or the medial temporal lobe (MTL) has a function in behavior selection with plural possible answers. We used an occupational choice task (e.g. which occupation do you think you could do better?-dancer or chemist) with two possible answers and a word-length task (e.g. which word is longer?-dentist or comedian) that has a correct answer. The conflicts in each task were manipulated. Results showed that the dACC and the MTL were activated when the conflict during occupational choice was large, and that the MPFC and posterior cingulate cortex were activated more in the occupational choice task than in the word-length task. Our results show that the dACC evaluates the degree of conflict between possible answers, and that the MTL, MPFC, and posterior cingulate cortex have a function in behavior selection without an objective correct answer. It is thought that the MTL functions to reduce conflict when a large-conflict is detected in the dACC. Furthermore, the MPFC and posterior cingulate are thought to have a function of biasing any of the plural answers in behavior selection without an objective answer. (C) 2009 Elsevier Ireland Ltd.

    Medial prefrontal cortex (MPFC) activation has been observed in studies of many types related to emotion regulation, self and familiar other-knowledge, mentalizing, morality, reward, and uncertainty. Furthermore, the anterior cingulate cortex (ACC) and the lateral prefrontal cortex (LPFC), which have reciprocal connections with MPFC, are considered necessary for cognitive regulation. Based on these findings, Nakao, Takezawa, and Miyatani (2006) proposed an integrative explanation for MPFC function: MPFC has a function of representing a benchmark that reduces conflict among many possible answers by biasing either choice of behavior. In this article, we review studies related to MPFC function and the benchmark hypothesis with recent new findings. Additionally, we discuss emotion regulation, which was not described in Nakao et al. (2006), in relation to the benchmark hypothesis.

    The present study aimed to investigate the dissociable effects of two forms of self-focus on emotional and autonomic responses. One form is Suppression, which includes the suppression of heart rate and self-evaluation of performance. The other is observation, which includes attention to one's own heart rate with no suppression and no evaluation. 26 undergraduate and graduate students from the Nagoya University campus (13 men, 13 women), ages 18 to 24 years (M=20.7, SD=1.6) were recruited. Participants were provided with their own heart rate as feedback for 5 min., during which participants conducted a self-focus manipulation. Several days after the experimental session for one condition, the same participants conducted another experimental session for the other condition. Instruction to suppress enhanced physiological arousal and subsequent negative emotions; however, instruction to observe did not increase physiological arousal or negative emotions.

    In visual oddball studies, deviant compared to standard stimuli elicited a posterior negative ERP at around 100-250 ms. To determine the underlying processes of the negativity, we used the equiprobable sequence in which bar stimuli of five types of orientation were presented with equal probabilities (control 20% each) as well as the oddball sequence in which two stimuli with the closest orientation were presented with different probabilities (deviant 20% and standard 80%). Deviant compared to standard stimuli elicited two negativities at around 100-150 ms with no hemispheric dominance and 200-250 ms with right hemispheric dominance, while deviant compared to control stimuli elicited only a negativity at around 200-250 ms with right hemispheric dominance. These results suggest that the early negativity reflects refractory effect, while the late negativity reflects memory-comparison-based change detection effect (visual mismatch negativity).

    It is hypothesized that experiencing positive emotions such as pleasure leads to a perception of the body being in a positive state. This study demonstrated associations among positive mood, brain, and cardiovascular activities by simultaneously recording these activities when positive emotions were evoked in participants watching films revolving around a love story. Heart rate variability analysis revealed increased parasympathetic nervous activity while watching the film. The following brain regions were significantly activated in the positive condition relative to the control condition: medial prefrontal. cortex, thalamus, superior temporal gyrus, inferior frontal gyrus, and cerebellum. Further, covariate analyses indicated that these brain regions were temporally associated with subjective positive mood. Activities of brain regions considered to be related to interoceptive awareness, such as the insular cortex, anterior cingulate cortex, amygdala, and orbitofrontal cortex, were also temporally associated with the cardiovascular change. These results suggest that while an individual experiences positive emotions, activities of the central nervous system and cardiovascular system may be interrelated, and the brain may perceive the body to be in a positive state.

    Metacognitive strategies of emotion regulation such as an objective perspective of one's self are known as primary factors in mindfulness intervention. Earlier studies, however, suggest that the effect of mindfulness differs because of the individual variability. In this study, we investigated the influence of the serotonin transporter gene polymorphism during the application of a metacognitive strategy of emotion regulation. Short (S) homozygotes showed more negative emotional states than SL individuals in both metacognition and control conditions. The high frequency of heart rate variability, however, increased in the metacognition condition only in S homozygotes. This result indicated that the metacognitive strategy of emotion regulation is more effective for increasing parasympathetic dominance in S homozygotes than in SL individuals.

    OBJECTIVES: Warm physical contact may positively influence our health and well-being
    however, it has not been investigated yet whether serum proteins are influenced by warm physical contact in healthy couples. In this study, we focused on psychological and physiological effects of warm partner contact in healthy couples. METHODS: When participants freely kissed and hugged their romantic partners, they were asked to subjectively evaluate their present emotions. Furthermore, changes of serum proteins were determined by using ProteinChip surface enhanced laser desorption/ionization-time-of-flight-mass spectrometry (SELDI-TOF-MS). We characterized these proteins by using biochemical techniques combined with gel filtration high performance liquid chromatography (HPLC), reverse-phase HPLC, and sequencing analyses. RESULTS: Romantic couples became happier and less irritated after kissing and hugging. Accompanying these psychological changes, SELDI-TOF-MS indicated that the intensities of 66-k Da, 11.7-k Da, and 5.9-k Da serum proteins were increased. These proteins were identified as serum albumin and β2- microglobulin, and probably fibrinogen fragment. The feeling of happiness positively correlated and the feeling of irritation negatively correlated with intensities of serum albumin and β2-microglobulin. CONCLUSION: These results suggest that psychological stress may be reduced and we may feel happiness when we kiss and hug a romantic partner. Furthermore, these results also suggest that warm partner contact influences peripheral circulating proteins, more importantly, may promote health and well-being.

    A short (S) variant, compared to a long (L) variant, of the promoter region of the serotonin transporter gene-linked polymorphic region (5HTTLPR) has been related to emotional hyper-reactivity. We tested whether the 5HTTLPR could modulate acute stress responses in the brain and, the cardiovascular and neuroendocrine systems. Ten Japanese male participants carrying double copies of the S alleles and 10 Japanese males carrying S and L alleles conducted a mental arithmetic task, and their regional cerebral blood flow by &lt;SU15&lt;/SUO positron emission tomography and cardiovascular and neuroendocrine parameters were measured. During the acute stress task, the participants with the SS alleles showed stronger reactivity in blood pressure and secretion of epinephrine, compared to the participants with the SL and LL alleles. Furthermore, the SS carriers showed greater activation in stress-related brain regions such as the hypothalamus, cerebellum, midbrain, and pulvinar compared to the SL and LL carriers during the acute stress task. The present findings indicated that the S allele of the 5HTTLPR is associated with greater brain and physiological reactivity to acute stress in Japanese men.&lt;/.

    Recent studies demonstrated that an acute psychological stressor elicited transient changes in lymphocyte redistribution. Earlier studies had established that CD3-CD16+CD56+ natural killer cells (NK cells) increased remarkably in peripheral blood circulation and that the amount of lymphocyte redistribution in NK cells was dependent on the CD62L expression density.
    Specifically, CD62L- cells were mobilized more pronouncedly than were CD62L+ cells. These results led us to hypothesize that such different reactivity causes different temporal characteristics between CD62L+ and CD62L- lymphocyte subsets.
    The present study was conducted to examine this issue. Ten female participants experienced a 10-minute baseline period and performed a 10-minute mental arithmetic task as an acute psychological stressor. Blood samples for measuring the proportions of CD62L+ or CD62L- NK cells and CD62L+ or CD62L- T cells were obtained immediately after each period and every 2 min during the task. As expected, CD62L+ and CD62L- NK cells showed different reactivity in response to the stressor and showed different temporal characteristics. That is, the elevation of CD62L- NK cells reached a significant level at I min after the initiation of the stressor, while CD62L+ NK cells took 8 min to show a tendency of elevation. Although CD3+ T cells showed different reactivity between CD62L cell types, they did not show different temporal characteristics. These findings suggest that the expression of CD62L modulates not only the amount of redistribution but also the temporal characteristics of the redistribution of NK cells. (C) 2008 Elsevier B.V.

    While faces are recognized viewpoint-dependently, familiar faces are recognized in a relatively viewpoint-independent manner. We conducted a cognitive ERP experiment to investigate the effect of viewpoint-independence for familiar-face recognition. The present results showed that facial angle differences were reflected by N170 latency and N250 amplitude. Furthermore, the N250 difference was attenuated in the left hemisphere for famous faces and in the right hemisphere for one&apos;s own face. We concluded that familiar faces are first recognized viewpoint-dependently, but then are represented viewpoint-independently. The laterality difference observed in N250 may be related to a self-relevant process in the Fight hemisphere, while a familiarity process is associated with the left hemisphere.

    Positive emotions are evoked on seeing one's favorite person. To investigate the psychological and physiological responses accompanying these positive emotions, we simultaneously recorded various parameters such as the mood state, heart rate, skin conductance level (SCL), serum levels of catecholamines, and proportions of T cells and natural killer (NK) cells among the lymphocytes while participants viewed films featuring their favorite persons. The participants reported that they felt better and invigorated
    in addition, SCL and proportion of NK cells in peripheral blood increased significantly, and these physiological changes were positively correlated. These results suggest that positive emotions elicited on seeing a favorite person may lead to psychological and physiological activation and, more importantly, may promote health.

    Recent studies on psychoneuroimmunology have indicated that positive psychological events are related to immune functions; however, limited information is available regarding associations among the central nervous, endocrine, and immune systems when positive emotions are elicited. In the present study, we demonstrated associations among these systems by simultaneously recording brain, endocrine, and immune activities when positive emotions were evoked in participants as they watched films featuring their favorite persons. Interestingly, the activity of peripheral circulating natural killer cells and the peripheral dopamine level were elevated while participants experienced positive emotions, and these values were positively correlated. The following brain regions were significantly activated in the positive condition relative to the control condition: medial prefrontal cortex, thalamus, hypothalamus, subcallosal gyrus, posterior cingulate cortex, superior temporal gyrus, and cerebellum. Further, covariate analyses indicated that these brain regions were temporally associated with endocrine and immune activities. These results suggest that while an individual experiences positive emotions, the central nervous, endocrine, and immune systems may be interrelated and attraction for favorite persons may be associated with the activation of the innate immune function via the dopaminergic system.

    Several studies reported that redistribution of lymphocyte subsets, especially CD3-CD16+CD56+ natural killer (NK) cells, was elicited by acute psychological stress tasks. It is known that lymphocyte redistribution was regulated based on active or passive emotional coping strategies, which can be elicited dependent on controllability of a stressor. Controllability can be evaluated gradually by learning of a contingency between actions and outcomes. Therefore, lymphocyte redistribution can be determined by learning of the contingency. To examine this issue, we used a stochastic learning task as an acute stress task and divided twenty healthy participants into reinforcement or yoked groups. Between the two groups, only whether they could learn the contingency was manipulated. As a result, patterns of changes in the NK cell numbers differed between the groups; NK cells remarkably increased at first and then gradually decreased to the baseline in the reinforcement group while the yoked group showed a moderate but sustained increase of NK cells. These patterns of changes in the NK cells were completely parallel with changes of the cardiovascular parameters but not with secretion of catecholamines. The present results suggest that cardiovascular and immune reactivity can be modulated along with progresses of adaptation for an acute stressor. (C) 2007 Elsevier Inc. All rights reserved.

    Psychopathologies such as depression and anxiety have been associated with self-consciousness, a trait focusing on the self in terms of emotions and social images. A technique designed to shift attention away from the self tends to reduce anxiety, so the present purpose was to assess the effect of self body-state information on an individual's emotional and autonomic activity. 24 undergraduate and graduate students (10 men and 14 women), ages 19 to 27 years (M-22.1, SD-2.5), were recruited as subjects. Focusing on body-state during an anxiety-inducing Situation led to an increase of low to high frequency ratio of heart-rate variability which reflected cardiac sympathovagal balance. That is, attending to one's own bodily states enhanced relative sympathetic activity compared to parasympathetic activity, which can be interpreted as one of the physiological emotional responses elicited by anxiety.

    The present study investigated the abnormalities of cardiovascular responses to contextual or explicit emotional stimuli with respect to the two facets of psychopathy in a Japanese undergraduate population assessed by a Japanese version of the Primary and Secondary Psychopathy Scales. In study 1, recording heart rate and fingertip skin temperature while the participants watched an unpleasant movie, we found that the participants with high tendencies toward antisocial behavior (n = 16) showed smaller reactivity than those with low tendencies toward antisocial behavior (n = 16). By contrast, in study 2, heart rate orienting responses to affective slides were recorded, and the participants with high tendencies toward emotional detachment (n = 15) showed smaller responses to unpleasant slides than those with low tendencies toward emotional detachment (n = 16). Consistent with previous studies which recorded skin conductance and startle eye blink with psychopaths, these findings using a non-institutionalized sample also suggest that affective dysfunction in psychopathy is based on two specific physiological mechanisms.

    Objective center dot This study investigated differences in relaxation induced by guided imagery in healthy community samples.
    Methods center dot One hundred forty-eight people took part in our investigation. The mean age of the 50 males and 98 females was 39.36 +/- 11.86 years. We took saliva samples to measure salivary cortisol (SC) before the first session, after the first session, and after the second session. Subjects were asked to complete the short form of the Multiple Mood Scale (MMS) questionnaire before the first session and after the second session. The shortened form of Betts' Questionnaire upon Mental Imagery (QMI) was collected once before the first session, and vividness of the imagery was measured using a visual analogue scale once after the second session.
    Results center dot SC levels were significantly decreased after the first session and after the second session in all participants. We found, most significantly, that age and QMI scores were strongly related to changes in SC level throughout the relaxation sessions.
    Conclusions center dot Unpleasant information, a cause of mental stress, is replaced by a comfortable image, and this replacement affects a participant's SC level. The greater one's imagery ability is, the more successful the displacement of stress and the shift toward a comfortable mental and emotional state will be. This study provides a basis for explaining the mechanism through which relaxation by means of guided imagery is effective in reducing stress.

    Recent neuromiaging studies have shown that several prefrontal regions play critical roles in inhibiting activation of limbic regions during voluntary emotion regulation. The present study aimed to confirm prior findings and to extend them by identifying the frontal neural circuitry associated with regulation of peripheral physiological responses during voluntary emotion suppression. Ten healthy female subjects were presented with affectively positive, neutral, and negative pictures in each of an Attending and Suppression task. Regional cerebral blood-flow changes were measured using O-15-water positron emission tomography, and autonomic (heart rate: HR, skin conductance response: SCR) and endocrine (adrenocorticotropic hormone: ACTH) indices were measured during both tasks. The left amygdala and the right anterior temporal pole were activated during the Attending task, whereas activation was observed in the left lateral prefrontal cortex (LPFC), including the adjacent medial prefrontal cortex (MPFC), and medial orbitofrontal cortex (MOFC) during the Suppression task. In the Attending task, activation in the amygdala and MOFC positively correlated with magnitudes of the SCR and ACTH responses. Emotion suppression elicited enhancement of SCR and the strength of the effect positively correlated with activation in the MOFC. These results suggest that the MOFC plays a pivotal role in top-down regulation of peripheral physiological responses accompanying emotional experiences. (c) 2005 Elsevier Inc. All rights reserved.

    Sympathetic nervous activity plays a prominent role in acute stress responses in the immune system, enhancement of innate immunity and suppression of specific immunity. The present study was conducted to examine the temporal characteristics of such immune responses to acute stress and to determine their association with sympathetic activity in detail. For this purpose, 15 female undergraduates engaged in a continuous mental arithmetic task for 14 min, and we collected their blood samples for immune indices (CD3+ T cells, CD4+ T cells, NK cells) each 3 min during the task and saliva samples before and after the task. Our results showed that the proportion of Natural Killer cells (NK cells) increased even 2 min after initiation of the task, whereas proportions of CD3+ and CD4+ lymphocytes decreased 8 min after initiation of the task. Moreover, we found significant correlations between cardiovascular activity and the variations of immune indices. (c) 2005 Elsevier B.V. All rights reserved.

    Feedback negativity is a negative component of the event-related brain potential observed 250-300 ms after feedback stimuli. The present study investigated the effects of value (correct or incorrect) and reward magnitude (no, small or large) on feedback negativity and P300. Feedback negativity was larger after incorrect feedback than after correct feedback, irrespective of reward magnitude. In contrast, P300 amplitude increased with reward magnitude, irrespective of value. The amplitude of feedback negativity was correlated with a trait score of negative affect and not positive affect, whereas P300 amplitude was correlated with positive affect and not negative affect. These results suggest that value and reward magnitude are processed separately in the brain. (c) 2005 Lippincott Williams F Wilkins.

    Although the neural basis of the unconscious priming effect has previously been investigated, the results of these studies have possibly been contaminated by a conscious priming effect. The aim of the present study was to dissociate the effects of conscious and unconscious priming on event-related potential (ERP) by using the process-dissociation procedure. A prime word was presented briefly, followed by a word-stem, in each trial. Under the inclusion condition, subjects were instructed to complete the word-stem using the prime word, while under the exclusion condition subjects were asked to complete the word-stem with a word not seen as prime. The behavioral priming effect was obtained under both conditions, indicating that the prime words were processed unconsciously and influenced the word-stem completion task. We found that two ERP components were affected by repetition priming. First, the N400 amplitude was decreased by word repetition under the inclusion condition, but not under the exclusion condition. This result suggests that N400 would reflect conscious lexical processing, but not unconscious lexical activation. Second, the negativity at left front lateral region was enhanced by word repetition under the exclusion condition. We discuss this finding herein in relation to the activity of the left inferior prefrontal cortex with regard to word semantic processing. (c) 2004 Elsevier Ltd. All rights reserved.

    Acute experimental stressors transiently increase volume of secretory immunoglobulin A (s-IgA) in saliva. The present study examined buffering effects of social support on response of s-IgA to a brief psychological stress (giving a public speech). 24 women were divided at random into three groups, an emotional support group, an informational support group and a no-support group (control). For each group, s-IgA measures were obtained from each person under baseline conditions, during preparation of a speech when social support or no support was given, immediately after the speech and during a 'recovery' period. Level of s-IgA in the control group significantly elevated during preparation for the speech and just after the speech compared to baseline, suggesting that the speech task stimulated secretory immune function. On the other hand, the subjects in the emotional support group showed increased s-IgA during the preparation period but secretion of s-IgA rapidly returned to the baseline after the speech task. Secretion of s-IgA in the informational social support group was unchanged at any measurement point. These results suggest that social support attenuates the affect of a stressor on somatic state.

    Previous studies have indicated that expression of negative emotions facilitates mental and physical health and inhibition of negative emotions increases susceptibility to illness. This study was conducted to examine whether those findings can be expanded to populations with non-Western cultural backgrounds. Specifically, we explored effects of expression and inhibition of negative emotions on health, mood states, and mucosal immune function in mildly depressed Japanese individuals. 16 depressed and 16 nondepressed female undergraduates were required either to write about their unpleasant experiences and superficial topics or to suppress any emotional responses and thoughts about them. Secretory immunoglobulin A (s-IgA) in saliva and psychological indices were measured at an experimental session and at a follow-up 1 wk. later. Beneficial effects of expression of emotions on subjective health were indicated in the nondepressed group, whereas harmful effects of inhibition on subjective health were shown in the depressed group. Emotional expression by writing improved mood states both in the depressed and nondepressed groups but induced elevation of salivary s-IgA only in the depressed group.

    Eyeblink activity was examined as a psychophysiological index of cognitive processing during a typical semantic priming task. To examine the expectancy-induced effects, the proportion of semantically related pairs was controlled. 8 undergraduates engaged in a lexical decision task for target words. Each condition differed in target type (Semantically Related with prime vs Unrelated vs Nonword) and proportion of Semantically Related pairs (High vs Low). As a result, the temporal distribution of blinks was clearly influenced by the semantic priming effect. The peak of blink bursts, which is correlated with the end of cognitive processing, occurred the fastest in the semantically Related and High proportion condition. While blink latency showed larger individual differences, the temporal distribution of blinks was suggested as a more efficient index of cognitive processing.

    The present study examined the functional association of the amygdala and right ventral prefrontal cortex (PFC) during cognitive evaluation of facial expressions. A situation was created where emotional valence of the stimuli was unconsciously manipulated by using subliminal affective priming. Twelve healthy volunteers were asked to evaluate the facial expressions of a target face (500-ms duration) such as "anger", "neutral", or "happy". All target faces expressed relatively weak anger. Just before the presentation of the target face, a prime of three conditions of 35-ms duration, angry face, neutral face, and white blank was presented. The subjects could not consciously identify the primes in this procedure. Activity in the right amygdala was greater with subliminal presentation of the angry prime compared with subliminal presentation of a neutral face or white-blank stimuli. Most importantly, the degree of activation of the right amygdala was negatively correlated with that of the right ventral PFC only with the anger prime. Furthermore, activation of the amygdala was positively correlated with rate of judgment when the subjects recognized anger in the target faces. These results are discussed in terms of the functional association between the right PFC and the amygdala and its influence on cognitive processing. (C) 2003 Elsevier Inc. All rights reserved.

    It has been found that an emotional stimulus such as a facial expression presented subliminally can affect subsequent information processing and behavior, usually by shifting evaluation of a subsequent stimulus to a valence congruent with the previous stimulus. This phenomenon is called subliminal affective priming. The present study was conducted to replicate and expand previous findings by investigating interaction of primes and targets in the affective priming effect. Two conditions were used, Prime (subliminal presentation 35 msec.) of an angry face of a woman and a No Prime control condition. Just after presentation of the prime, an ambiguous angry face or an emotionally neutral face was presented above the threshold of awareness (500 msec.). 12 female undergraduate women judged categories of facial expressions (Anger, Neutral, or Happiness) for the target faces. Analysis indicated that the Anger primes significantly facilitated judgment of anger for the ambiguous angry faces; however, the priming effect of the Anger primes was not observed for neutral faces. Consequently, the present finding suggested that a subliminal affective priming effect should be more prominent when affective valence of primes and targets is congruent.

    The purpose of this study was to examine the effects of listening to high-uplifting or low-uplifting music after a stressful task on (a) immune functions, (b) neuroendocrine responses, and (c) emotional states in college students. Musical selections that were evaluated as high-uplifting or low-uplifting by Japanese college students were used as musical stimuli. Eighteen Japanese subjects performed stressful tasks before they experienced each of these experimental conditions: (a) high-uplifting music, (b) low-uplifting music, and (c) silence. Subjects' emotional states, the Secretory IgA (S-IgA) level, active natural killer (NK) cell level, the numbers of T lymphocyte CD4+, CD8+, CD16+, dopamine, norepinephrine, and epinephrine levels were measured before and after each experimental condition. Results indicated low-uplifting music had a trend of increasing a sense of well-being. High-uplifting music showed trends of increasing the norepinephrine level, liveliness, and decreasing depression. Active NK cells were decreased after 20 min of silence. Results of the study were inconclusive, but high-uplifting and low-uplifting music had different effects on immune, neuroendocrine, and psychological responses. Classification of music is important to research that examines the effects of music on these responses. Recommendations for future research are discussed.

    The effects of negative air ions on computer operation were examined using a biochemical index of the activity of the sympathetic/adrenoniedullary system (i.e. salivary chromogranin A-like immumoreactivity (CgA-like IR)) and a self-report questionnaire (State-Trait Anxiety Inventory, Anxiety State-STAI-S). Twelve female students carried out a word processing task for 40 min. The salivary CgA-like IR increased more than three times on the task, but the salivary cortisol did not change. The increase in the CgA-like IR level was attenuated by the exposure to negative air ions during the task. The exposure to the ions during the recovery period following the task was effective for rapidly decreasing the CgA-like IR level that had increased after the task. These effects by negative air ions were also observed using STAI-S. Task performance was slightly but significantly improved by the presence of negative air ions. These results suggest that negative air ions are effective for the reduction of and the prompt recovery from stress caused by computer operation. (C) 2002 Elsevier Science B.V. All rights reserved.

    This article presents findings of a laboratory experiment on the association of the Type A behavior pattern with reactivity of secretory immune functioning to brief stress. 38 female undergraduate students classified as Type A (n=19) or as Type B (n=19) on the basis of their scores on the Kwansei Gakuin Type ii scale performed a continuous arithmetic task in a situation in which they were exposed to aversive loud noise. Secretory immunoglobulin A (s-IgA) in saliva and autonomic measures (heart rate and frequency of eyeblink) were evaluated before and after the manipulation of stress. The volume of s-IgA at baseline was significantly higher for the Type A group than for the Type B group, suggesting that the former relative to the latter might be chronically higher in mucosal immune functioning. Also, the volume of s-IgA significantly increased after exposure to a brief stress for the Type B group bur did not change for the Type A group, a finding which might indicate that the Type A group may have less immune reactivity to a brief stress.

    Japanese college students viewed a series of positive and negative stimulus words printed in katakana, a Japanese syllabary. Jacoby's process-dissociation procedure was wed to assess the roles of conscious and unconscious processes in stimulus recognition. There was a stronger conscious recollective component in recognition of negative items and a higher correct rejection rate for negative stimuli, replicating American findings reported by Robinson-Riegler and Winton, and Ortony, Turner and Antos. In addition, during the encoding phase, negative stimuli were associated with more eyeblinks and longer eyeblink latencies than positive stimuli; this pattern suggests greater cognitive activity in response to negative stimuli, consonant with Taylor's mobilization-minimization hypothesis. The eyeblink response, as measured in the present research, represents a new method for assessing the positive-negative asymmetries that are characteristic of the mobilization process.

    Eyeblink activity was examined based on a discrete-trial paradigm in which 17 subjects engaged in a semantic priming task. They were presented a series of pairs of words (prime and target) associatively related or associatively unrelated and were required to name them as quickly as possible. Cognitive load or difficulty of naming of the target word was also manipulated. The latency data for naming of the target word showed a typical priming effect, namely, facilitation of naming speed by the associatively related prime word. The eyeblink rare changed synchronically to onset of stimuli as a function of prime-target relationship and cognitive load during the task. Specifically, the eyeblink rate was suppressed during presentation of the target word and peaked just after that. This study showed that suppression of eyeblinks was longer on trials with high cognitive loads than on those with low cognitive loads and the peak of eyeblink rate was higher on trials for which the prime and target were unrelated than on those for which they were related. These results suggested that the eyeblink activity is influenced by inner cognitive processes of word recognition.

    This study was designed to assess characteristics of self-referent information processing in mildly depressed persons using the eyeblink response measured in a discrete-trial paradigm. 7 mildly depressed and 9 nondepressed subjects (classified by scores on Beck's inventory) performed a self-reference task for positive and negative trait adjectives. The eyeblink was suppressed before and during presentation of stimuli and a burst pattern of the eyeblink was observed just after exposure. The pattern of the eyeblink burst after trait adjectives could be interpreted to reflect cognitive effort, cognitive load, or amount of attentional resource. Present results suggested that depressed individuals should have less cognitive load or allocate less attentional resource to negative stimuli than to positive ones during self-referent information processing.

    The present research was conducted to examine the relative roles of recollection or intentional and controlled rocess and familiarity or automatic process in recognition memory of affectively positive and negative stimuli. Twenty subjects performed a memory task based on Jacoby's (1991) process dissociation procedure and their eyeblink activity was assessed as a secondary measure which should reflect inner cognitive processes. Results of memory performance indicated that the role of recollection was lower in recognition of affectively positive items than in recognition of affectively negative items. On the other hand, the role of familiarity was especially high in recogni- tion of positive and high arousal items. In addition, the results of eyeblink activity suggested that the process of memory scanning should be performed longer and probably more repeatedly for the positive and high arousal items in a memory test stage.

    Information processing approaches of depression in social psychology have argued thata depressed person has stronger links between node of self and those of constructs with negative valence in his or her associative network of memory, thus such negative constructs become more accessible during self-reference information processing. Be-havioral measures used in previous experimental studies on the problem, however, could not reflect directly the internal steps of processing. This study tried to assess the construct accessibility using eyeblink response measured in a discrete trial paradigm in which depressed and nondepressed subjects conducted a self-reference task for positive and negative trait adjectives. The eyeblink was suppressed before and during presentation of stimuli and a burst pattern of the eyeblink was observed just after it. Results of this study suggested that the pattern of the eyeblink burst after stimuli could reflect cognitive effort, cognitive load, or amount of attentional resource, therefore construct accessibility could assessed by using the eyeblink response as a measure.

    Two experiments were conducted to examine effects of facial expressions upon social cognitive processes in which the impression of another person is formed. In each experiment, 30 female college students were induced to display or conceal their facial reactions to a hypothetical target person whose behaviors were mildly hostile (Exp. 1) or mildly friendly (Exp. 2), or their facial expressions were not manipulated. Displaying the facial expressions shifted the impression into the congruent directions with hedonic values corresponding to the facial expressions. Concealing the facial expressions, however, did not influence impression formation. Also, the positive-negative asymmetry was observed in the facial feedback effects, that is, the negative facial expression had a stronger effect on social cognition than the positive one.

    It has been maintained that depressed persons have higher accessibility in constructs with negative valence, thus they are negatively biased in self-referent information processing. Behavioral measures used in previous experimental studies on the problem, however, could not reflect directly the internal steps of processing. This study examined the differences between the cognitive processes in depressed and nondepressed persons by using both P300 component of event related potentials (ERPs) and reaction time (RT)in an odd-ball like self-referent task. The negative stimuli elicited larger P300 amplitudes and longer P300 latencies than positive and neutral ones in the depressed subjects, whereas the reversed patterns were found in the nondepressed. The results suggest that ERP and RT are sensitive to different cognitive steps to process information concerningthe self.

    Two experiments were conducted to examine effects of physiologicalarousal and unconscious processing of trait words on impression formation ofothers. It was predicted that cognitive complexity of others' impression woulddecrease in a high arousal state because attentional resource might be restrictedin such a state. Furthermore it was hypothesized that the priming effect of traitword processing would be facilitated in a high arousal state. In each experi-ment, subjects rated the impression of a hypothetical target person after theyprocessed hostile, neutral, or friendly words which were presented at a sublimi-nal level in either high or normal arousal state. Results of both experimentsmade it clear that the impression of the person was simpler and more extremein high arousal conditions. However, effects of unconscious priming were notfound in each experiment. These results were discussed in terms of constructsaccessibility' models.

    Four experiments were conducted to examine the validity of facial electromyagragh (EMG) as an index of emotional expression behavior. During recalling or imaging past emotional experiences, individuals express some facial expressions. These expressions were, however, usually too subtle to be observed directly.In the present study, it was suggested that facial EMG could be a useful index of "potential" expressions. It was found that during recalling past positive events the activity of subjects'zygomatics-major region (cheek) muscles was facilitated and during recalling negative events the activity of corrugator region (upper blow) EMG was activated (Experiment 1). When a subject who had strong tendency of social anxiety imaged some interpersonal situations, the activity of corrugator and frontalis region (forehead) EMG was facilitated and the amplitude of EMG activity was positively correlated with the magnitude of anxiety that the subject evaluated (Experiment 2). Furthermore, it was found that the cognitive processing of affect-related words influenced the activity of facial EMG. The depth of processing influenced mentalis region (jaw) EMG activity and the valence of affective words (positive vs. negative) influenced zygomatics and corrugator EMG activity (Experiment 3,4).

    文化的集団淘汰仮説は、人類史における集団間の争いが人間の協力性を発達させたと主張する。本研究はこの仮説を多様なアプローチにより検討し、次のような知見を得た。1.他者への同調と規範遵守の傾向はリスク忌避傾向と関連することを示し、その神経基盤を明らかにした。2.集団間の社会的ジレンマを検討する実験課題を開発し、日本人における内集団ひいきと外集団嫌悪が社会性に媒介されていることを示した。また、その神経基盤を検討した。3.ヒトに近い野生ヒヒにGPSを装着して観察研究を行い、群れ間の協力の進化的要因を検討した。4.コンピュータ・シミュレーションにより、他者への協力と攻撃の要因を理論的に検討した。
    近年、国際社会は、自国第一主義と排外的傾向の高まりにより分断化が進んでいる。また、COVID-19の蔓延により同調圧力が高まる一方で、自分たちと異なる他者を怖れ攻撃する風潮が目立っている。現代社会では、まさに自己が所属する集団への協力とそれ以外の外集団への対立という図式が際立っていると言えるだろう。このような状況において、人間がなぜ葛藤と協力という2面性を持つのか、それはどのような時に、どのようなメカニズムにより顕著化するのかを解明することは喫緊の課題である。本研究は多用な立場と手法により、この困難な問題に実証的にアプローチし得たという点で、大きな学術的・社会的意義を持つ。

    本研究は、人間の意思決定について、経験に基づくボトム・アップ的で直感的なモデルフリー方略と、熟慮的・計画的でトップダウン的なモデルベース方略の心理・神経的基盤を解明することを目的とした。両方略を検討するための実験課題と強化学習モデルに基づく計算論モデルを開発し、心理行動的研究を行ってその妥当性を検証した。さらに、脳内の神経伝達物質を測定できるMRSと、脳ネットワークのダイナミクスを測定できる安静時fMRIを用いた神経画像研究により、両方略の神経メカニズムを探索した。その結果、モデルフリー方略には線条体と島皮質が、モデルベース方略には前頭前皮質が重要な役割を果たしていることが明らかになった。
    商品の購買から、就職や結婚の選択、病気の治療法や災害避難の選択まで、我々の人生は意思決定の連続である。我々がどのような原理により意思決定を行うかを解明することは、人間の理解や社会における政策の決定などに重要な意義を持つ。
    これまで、感情は理性と対立するものであり、意思決定を不合理に歪めるものと考えられてきた。しかし近年では、感情や直感に導かれた意思決定は、理性による意思決定を相補うものと考えられている。本研究は、直感的な意思決定(モデルフリー方略)と理性的な意思決定(モデルベース方略)の心理・神経的基盤の一端を明らかにしたという点で大きな学術的・社会的意義がある。

    本研究は、集団が伝承や伝統を通して暗黙裡に共有する「集合的記憶」の概念を、数理物理学から生まれた「確率共鳴」理論や神経科学における身体の内受容感覚モデルを応用し、世代を超えた「記憶の共有」という現象を、「共振・共鳴」という身体現象を指標として考察した。メンバーがみな互いに異なる領域をフィールドとするため、毎年研究会を継続し、それぞれの知見を交換しあうと共に、その成果は、毎年メンバーが各自国際研究集会で発表してきた。最終年度の成果として、メンバーの一人は国際研究集会における発表に対し受賞し、代表者が編者となって平成30年度研究成果公開促進費(学術図書)の助成を受け、論集(総580頁)を刊行した。
    集合的記憶が問題となるのは、戦争の記憶やその継承において、集団における記憶の共有が共同性の礎をつくるのか、それとも共同性が記憶の共有を可能とするのかという問いを提起するからである。私たちは、自分が生い育った文化的空間の中で、無自覚のうちに多くの記憶を背負っている。そのために、心理的のみならず、身体的な観点からも、共鳴という現象を考察する必要があるのである。身体受容感覚における生成モデルや確立共鳴理論への参照は、政治的イデオロギーや「民族」などナショナルな枠組みとは別の形で記憶の継承を論じる可能性を開くという点で、新しい視座を獲得するものであった。

    本研究は、不快感情の制御に重要な迷走神経系を、経皮迷走神経電気刺激により活動亢進させ、不快感情とそれに伴う交感神経系・内分泌系・炎症の反応を抑制できるかを検討することを目的とした。しかし経皮迷走神経電気刺激装置が日本に輸入できないことが明らかになったため、1分間6回程度の深呼吸により迷走神経活動を活動亢進させる方法に変更して予備的研究を行った。この結果、この方法により迷走神経系活動を亢進できることが明らかになったが(研究1)、不快感情に伴う各種反応を抑制する効果は見られなかった(研究2)。これは、刺激強度が不足していたためと考えられ、今後より頑健な刺激方法を開発する必要が示唆された。

    ロボットが人間と真に共生するには、そのロボットは<個性>を持たねばならない、というのがわれわれの出発点である。しかし、その<個性>とは何であろうか? われわれの哲学的分析では、<個性>をもつとは、それが<道徳的な行為主体>になるということである。
    この哲学的テーゼを経験的なレベルで実証するために、人とロボットとの一連のインタラクション(相互交流)実験を開発し、実施したことが、本研究の全体像である。その実験の結果、われわれは、このテーゼに対してある程度の肯定的な支持を得ることができた。こうして、ロボットの<個性>と<道徳性>に関する哲学的仮説に、実験的検証の道が拓かれたのである。
    本研究の社会的意義は、ロボット時代の先を見据えた<人間・ロボット共生社会>の中心課題に正面から切り込み、その解決に一定の見通しを得た点にある。その中心課題とは、暗に人々が最も懸念している問題、つまり「自律した知性ロボットは人間とどう共生しうるのか?」という問いである。
    この問題に対して、我々は、単なる道具ではないロボットは<個性>を持たねばならず、<個性>を持つとはそれが<道徳的行為者>となることなのだという哲学テーゼを以て答え、しかもそれに、ある種の実験的な確証を与えた。道徳問題というロボット時代の真の難問にこの方向性を示しえたことは、今後の社会に対して極めて大きな意義を持つと言える。

    2015年度から2017年度にかけて3つの対人的相互作用に関するfMRI実験を実施した。2015年度の実験では、コストのかかる謝罪が誠意のシグナルとなっているかどうかを検討した。その結果、コストのかかる謝罪を受け取る場面を想像するほど意図性推論に関連する脳部位が活動することを見出した。謝罪は関係へのコミットメント・シグナルと考えられるため、2016年度は謝罪以外のコミットメント・シグナルに反応する脳部位を知らべた。その結果、価値計算にかかわる部位が活動していた。2017年度の実験では、集団謝罪に対して活動する脳部位を調べ、それがが対人的謝罪に反応する脳部位と部分的に一致することを確認した。

    人間と動物の違いの一つは、感覚のみではなく、そこから成立する記憶と経験に基づいて理性的に生きようとする点にある。その際に人が依拠するのは事実に限らない。むしろたとえ事実とは異なっていても、記憶がその人の将来の行為、および過去の出来事の評価を左右するのである。また、人間の記憶は無限でないがゆえに、文字による記録による知の伝達が重要となるが、蓄積したものを取り出す過程で、可塑的な人間の脳に留められた記憶は次々に書き換えられ、それがさらに人の幸不幸に影響を及ぼす。本研究では、哲学、文学、美学、心理学、精神科学の共同の下、こうした問題に各分野の研究者が取り組み、それぞれ一定の成果を上げた。

    安静時心拍変動が大きい個人はストレス制御能力が高い。そこで本研究では、人為的に心拍変動を高めることでストレス制御能力が促進するのではないかという仮説に基づき、呼吸統制に基づいたバイオフィードバック訓練により心拍変動を高め、その後に時間圧を伴う暗算課題により急性ストレスを負荷してストレス反応性への影響を検討した。
    実験群では10分間のバイオフィードバック訓練を、休憩を挟んで2回行うことにより、心拍変動の低周波成分が頑健に増強した。また実験群では、訓練を行わなかった統制群と比較し、主観的ストレス反応と炎症性サイトカイン反応が減衰しており、心拍変動上昇がストレス制御能力を促進することが検証された。

    Fear&Russell(1984)は、感情概念間の関係は「感情」を上位概念とする階層構造を示し、さらに「感情」の典型的属性を備えた「中心概念」と典型的属性が不足する「周辺概念」に分けられること、またさらに感情概念はしばしば感情以外の心理学的概念に内包されることを報告した。われわれ(朴他、2010)は日本人と、韓国人を被験者として感情を上位概念とする感情の下位概念を調査し、出現率が80%を超す概念は日本人では「悲しい」、韓国人では「キップン(pleasure)」と「スルプン(sadness)」であり、感情語によってその出現頻度が異なることを報告し、出現頻度の高い語を中心概念、低い語を周辺概念と定義した。この結果に基づき、まず、中心概念に分類された語と、周辺概念に分類された語の上位概念を調べたところ、日本人では周辺概念に分類された語に比べ、中心概念に分類された語の上位概念は「感情」であると同定されることが多かったのに対し、韓国人ではそのような傾向はあまり見られなかった。また、感情の周辺概念の語を挿入した感情エピソード文よりも、中心概念の語を挿入した文の方が、より自然であると、日本人は評価することが示された。これらの成果は、ISRE(International Society for Research on Emotion)2011や日本心理学会で報告し、現在執筆中である。またこの他、本年度、中心概念とされるごと、周辺概念とされる語、各15語ずつの計30項目を用いて、この語を3,6,11,14のグループに分類させる実験を行い、その類似性を調べ、MDS(多次元尺度構成法)によって布置し、クラスター分析により、グループ分けした。その結果、中心概念は快-不快の軸に関係し、周辺概念は活性-不活性の軸に関係するという非常に明確な関係性が示された。この成果も外国誌に投稿すべく準備を進めている。

    本研究は仮想市場法(CVM)の問題点を克服する理論の構築と改善を目的に、特に神経科学の知見を考慮した分析を行った。これまでのCVMなどの表明選好法の主要な問題点は仮想性の存在とincentive compatibility(誘因両立性)の困難性にあった。仮想性は表明選好法に特有な問題で、これを減らす方法として、調査結果が少なくとも現実社会に影響を与えるようにする、あるいは表明時点になるべく現実の意思決定に近い状況を設定するなど、様々な試みがなされている。これらは現実的な手法の改善としては有効である。本研究ではconsequentialityに着目した。一方Incentive compatibilityは公共財の供給に関しては、不可避の課題である。しかしこの解決は現在の経済学ではほとんど絶望的である。さらに表明選好においては、表明額そのものに、ワォームグロー(war mglow)含まれる可能性が高くその同定は、費用便益分析を実施する観点からは極めて重要な課題である。本研究ではこの点に関して、仮想ではなく、実支払いを伴う実験を行い、その行動の解明を試みた。その結果はwar mglowは存在し、その動機は対人的な関係性に極めて依存していることが判った。また、これらの人間行動の解明は社会調査や実験室実験だけでは不可能であり神経科学的な方法論の適用が考えられる。そこで本研究では社会状況は複雑すぎるので、まず個人的な状況下での、刺激と意思決定の関係を分析した。その結果は、意思決定がなされる前に、身体状況に反応があらわれ、かつ行動に現われるまえに、神経的な反応が現れることが確認できた。

    本研究の目的は、トラウマの筆記表現(筆記開示)が心身の健康増進・高次認知機能に及ぼす影響に関して、文化心理学・健康心理学的観点から検討することであった。自由に感情や思考を筆記する従来の方法は、健康と認知の効果に関して、統制条件のそれを上回れないことが我が国とベルギーでは示唆された。しかしながら、トラウマに対する認知的再体制化が促進される構造化開示は、精神的健康(外傷後ストレス反応の低減)および高次認知機能(ワーキング・メモリー容量の増大)を改善させることが我が国において示唆された。

    サイコパシーとは、利己的・衝動的で、犯罪のリスクが高い性格特性である。このような一見、社会的に不適応的な性格特性が、人口中一定割合維持されているのは、この性格特性が有利に働く場面があるからだと考えられる。
    このような問題意識のもと、本研究では「最後通牒ゲーム」と呼ばれる行動経済学的な意思決定課題を用いて、合理性と感情が葛藤を生じるような場面で、サイコパシー特性が報酬獲得に有利に働く可能性を検討した。この課題では、ある金額を2人で分ける場面が想定され、相手の提案を受諾するか拒否するかの決定が求められる。不公正な提案がなされた時、合理的に受諾して報酬を確保するか、損失にも関わらず感情的に拒否するかのジレンマ事態が生じる。
    平成19年度には、サイコパシー傾向の高い個人は、不公正な提案に対しても心拍・皮膚電気反応などの自律神経系反応が見られず、受諾確率も高いことが見出された。これは、こうした個人で感情反応が弱いことを反映していると考えられる。平成20年度には、同じ課題を遂行中の脳活動を、fMRIにより検討した。その結果、不公正な提案がなされた場合、感情処理を担う島、前部帯状皮質、前頭眼窩皮質などと、意思決定を担う背側線条体に賦活が観測された。ところが、サイコパシー傾向の強い個人では、感情に関連する脳部位の賦活が顕著に弱いことが見出された。
    これらの結果は、サイコパシー傾向を有する個人は感情に欠如が存在すること、それがために不適応に陥る場合もあるが、反面、自己の感情を抑制して合理的に振る舞うことを求められる場面では、かえって適応的になることもありうることを示した。これらの知見により、サイコパシーという特殊な性格特性の理解を、より深めることができたと考えられる。

    本研究ではネガティブ感情体験の扱い方(処理様式)が生物学的状態や心理行動に与える影響を調べる複数の実験を実施した。主な知見は(1) ネガティブ感情の処理様式は「自我統合性」「調律」「外在化」「侵入」「回避」「解離」「抑制」「統制効力」という8つに類型化され、いずれの様式が優勢であるかという点で個人差が存在すること、またなかでも「抑制」が実際のストレス負荷状態からの自律神経系の回復を遅延させること、(2) ネガティブ感情経験に関する思考は実行機能(ワーキングメモリ機能)を低下させるが、ネガティブ感情経験の思考を阻止(抑制)することが特に実行機能の低下を導くこと、一方、ネガティブ感情経験の筆記による言語化の促進は実行機能を改善すること、(3) ネガティブ感情経験に一定のポジティブな価値をおく人々は日常生活におけるネガティブ感情の経験と表出が柔軟に示されること等である。また、(4) ネガティブ感情経験に向き合い受容するための適応的かつ効果的な方法として「花」を見つめ触れること、あるいは「いけばな」制作が役立ちうることを明らかにした。これらの研究結果は、ネガティブ感情を無視したり単純に抑え込むことが効用よりも弊害をもたらすこと、各種の処理様式を学習して実行することでネガティブ感情と上手に折り合いをつけ、心身機能を適応的に調節することが可能であることを示唆する。

    平成18年度は、PETを使用した実験的研究によるコントロール可能性の記憶部位の探索と、光トポグラフィー(NIRS)を使用した確率学習課題によるコントロール可能性可能性の操作に対する脳機能の解明を行った。
    1. PETを使用した確率学習課題による実験により、コントロール可能性の責任部位を同定し、これらの部位と生理的ストレス反応指標との間の相関を確認した。内側前頭前野(BA32)他の部位が、コントロール可能性が低いとの認知と関連しており、またこの部位の活動が血圧・心拍・免疫・心理反応などのストレス反応と正の相関をしていた。
    2.光トポグラフィーを用いた研究について日立基礎研究所と共同研究契約を締結し、光トポグラフィー測定系に、確率学習課題による心理学的実験システムの組み込みを行い、光トポグラフィーを用いた職業性ストレス理論モデルの脳内機序の解明のための汎用実験系を確立した。
    3.本研究の解析方法について、国際行動医学会(タイ)の場を利用して、関連する専門家から助言を受けるとともに、研究成果の一部を発表した。
    以上から、コントロール可能性の記憶担当部位が前頭前野内側にあることがほぼ明らかとなり、この部位の機能が仕事の要求度や急性ストレスに対する血圧・心拍・免疫・心理反応を修飾していることが示された。職業性ストレスモデルである要求度-コントロールモデルの神経基盤を明確にし、また光トポグラフィーを用いた汎用実験系を確立し、今後の本領域の研究の進展に寄与した。

    本研究は,感情の抑制や表出が心身の健康にどのような影響を与えるかを解明することを目的とし,PET研究班,トラウマ研究班,目常的感情研究班の3つの研究班を構成し,研究を遂行した。PET研究斑の任務は,感情抑制・表出に関する神経的・生物学的メカニズムを解明することであった。陽電子断層撮影法(positron emission tomography:PET)による脳機能測定と各種の生理反応の同時記録を組み合わせた研究方法により,感情制御の脳-身体基盤に関する重要な知見を得た。そこでは,前頭眼窩野,内側前頭前野を中心とした前頭ネットワークの重要性が示唆された。トラウマ研究班は,トラウマ(心的外傷)的体験を,能動的に認知処理(意識化・言語化・洞察・意味づけ)することが心身にもたらす影響について実験心理学的方法により検討した。その結果,感情の言語化は,認知的構造や認知的機能を変容することで心身の健康に実際に影響を与えうること,そこではワーキング・メモリ機能が中核的な役割を果たすことが明らかになった。これは,感情に関する臨床心理学・健康心理学的な問題と認知心理学的な概念を結びっける成果であると言える。日常的感情研究班は,社会心理学的な調査的方法ど実験的方法により,感情の抑制・表出の個人差要因と,感情抑制・表出の中・長期的な効果を解明することを目指した。その結果,感情抑制・表出の個人差を規定する要因として自己隠蔽傾向と抑制的会話という特性が浮かび上がり,その心理学的性質が詳細に検討された。また日記という形式での怒り感情表出により,比較的長期間にわたり有効に不快感情を制御しうることを見出した。特に後者の成果は,これまで主として実験室で研究されてきた感情の抑制・表出の問題とその知見が,日常生活にも応用・実践が可能であることを示唆するものであり,健康心理学的に重要な意義を持つと考えられる。

    研究代表者は、本研究の前に科研費の援助を受けて、3ヶ月児から93歳の高齢者までの14の年齢集団約1400名のデータに基づいて、内因性瞬目の発達的変化に関する研究を行った。その結果、新生児はほとんど瞬目をしないが、その後徐々に増加し、10歳前後でほぼ成人の域に達し、その後は高齢者まで大きな変化はないこと、などを中心に瞬目の発達過程に関するかなり詳細な記述をした。この成果を元にさらに系統発生の実態を霊長類で検討しようとしたのが本研究である。解析は、瞬目率、瞬目持続時間、それに単独瞬目率(頭部運動を伴わない瞬目の回数)の各測度について、貢献因子として当面考えられた、身体サイズ(体重・頭胴長)、2つの系統差(通称の4水準、科の7水準)、生活リズム(夜行性と昼行性など)、生息環境(樹上性と地上性など)、ついて実施した。その結果、霊長類の瞬目率と瞬目時間は平均するとヒトのほぼ半分になる。つまり、頻度も時間も極めて小さい、ことが明らかになった。しかし、これを種ごとに大小の順位で並べてみると、瞬目時間には余り大きな差はなかったが、瞬目率と単独瞬目率の変異は極めて大きいことが分かった。この差をもたらす要因は何かが問題であるが、当面の結論は、「瞬目は、1)夜行性から昼行性へ、2)樹上性から地上性へ、3)小さいサイズから大きいサイズへ、そしてしたがって、4)系統の順序に従って、1)瞬目率の上昇、2)単独瞬目率の上昇、しかし、3)瞬目持続時間には影響が少ない」という、個体発生と近似する傾向を認めたことである。しかし、さらにチンパンジーは赤ちゃんで既に瞬目が頻発するという予想外の観察をして、今また混乱している。また、日常的な観察によれば、霊長類以外でも結構頻発する種や個体がいることも観察していて、今後に残された問題も多いことを注記しておきたい。

    高齢者の下限定義に該当する65歳時点の生活習慣、体力、免疫能などの違いがどのように老い(死亡、罹患、認知症、寝たきり)に影響を及ぼすかを検討し、さらにこれら情報を元に健やかに老いることを目指した積極的な働きかけを提案するために研究を行った。本研究は1996年度から2005年度までN市で開始された65歳すこやか健診をベースとして10年間継続し、その結果、3098名の65歳コホートが構築された。追跡のために、ベースライン時点より6年後に生存しかつN市内に在住する者に対して健康状態調査を行っている。健康状態の把握には、2002年度に開始された70歳ことぶき健診の場を用い、6年間の疾病罹患ならびに6年後の時点での検査値異常を調査した。さらに、未受診者には市と共同した調査を行い、認知症、寝たきりへの移行も調べた(訪問調査)。死亡、転出は市と協力して把握しており、この調査は、2005年度受診者が70歳健診を受診するまで継続する予定である。
    本コホートのベースライン・データからは、国民栄養調査などで示された当該年齢層の日本人の一般的な像とくらべたときやや健康サイドにシフトしているものの、全体として著しい差異はないことが明らかとなっている。今後、本コホートを追跡・分析することによって、普通の日本人の高齢者の入り口における毎日の過ごし方や環境が、その後の良好な状態にどのように影響するかを解明する糸口になるものと思われる。

    本研究結果は特定の認知機能にかかわる脳内の神経相関を検討する上で、機能的磁気共鳴画像(fMRI)で得られた空間的情報と事象関連電位(ERP)で得られた時間的情報を効果的に組み合わせることが有用であることを示している。最初に行われた顔認知研究では、fMRIで計測された側頭-後頭葉領域の信号値の変化とERPで測定された同領域の電位変化との間に相関関係が見られた。しかしより高次な処理を行う前頭葉領域では、このような明確な相関関係は認められなかった。従って本研究の主題となる再認課題に関する実験では、両実験を別の被験者群を用いて行った。
    健常若年被験者で絵の再認課題を遂行中のfMRIとERP実験を行い、記憶に関する脳内メカニズムを探った。fMRIでは想起の成功に関る領域として、前頭-頭頂葉領域が賦活された。さらに記銘時の処理水準操作の結果から、中でも左半球の頭頂間溝と前頭前野の一部がrecollectionに関わると考えられた。ERPでは想起の成功に関係して、刺激呈示後400〜500ミリ秒付近で頭頂部領域の電極で陽性の電位変化が認められた。この両者は実験の内容から考えて、同一の神経機構を反映するものと思われる。
    最後に健常高齢者を対象として、ほぼ同一のfMRI実験を行った。その結果では高齢者で想起時に認められる前頭葉の強い脳賦活は、高齢者での有意に長い反応時間と関係している可能性が示された。また想起の成功に関る領域として、高齢者では海馬の信号低下と脳梁膨大部後部皮質の信号上昇が特徴的であった。この結果は正常な加齢による海馬機能の低下を、同じPapez回路の一部である膨大部後部皮質が補完している可能性を示唆している。

    急性ストレスに対する免疫応答についての基礎的知見を得るため,暗算課題,冷却昇圧課題を負荷して各種免疫細胞の末梢循環数を解析した結果,自律神経系の亢進と共に,NK細胞などの細胞性免疫の亢進,T細胞,B細胞などの液性免疫の抑制という二相的反応が頑健に観察された(Isowa, Ohira, & Murashima,2004).さらに,これらの反応は,遅くとも2分以内には生起する極めて鋭敏なものであること,NK細胞の反応はT細胞やB細胞の反応よりも早いこと,などが確認された(Kimura, Isowa, Ohira, & Murashima, in press.).
    これらの知見を基に,ストレス課題におけるコントロール可能性を操作して,それが免疫動態に及ぼす効果を検討した.その結果,コントロール不能な事態では自律神経系の亢進がいくぶん抑制されると共に,自律神経系活動と免疫反応の対応がきわめて高くなることが示された(Isowa, Ohira, & Murashima, in press.).これは,事態がコントロール不能であると認識されると中枢によるトップ・ダウン的制御が働いて,環境に適応するために自律神経系を介して免疫系を積極的に制御しようとする機構の現われであると解釈された.

    急性・一過性のストレス負荷が免疫系機能を変動させることが知られており,これは生体へのチャンレンジに対する防御的反応であると考えられてきた.一方,心理学領域では従来より,同一のストレス負荷であっても,それが主体の側でコントロール不可能な場合には,そのインパクトはより大になると考えられてきた.本研究は,ヒト被験者に実験的に急性ストレスを負荷し,その前後での免疫・内分泌系物質を定量することにより,急性ストレスのコントロール可能性が免疫・内分泌系反応を修飾するか否かを検討した.
    1 平成12年度には,キー押しによる嫌悪刺激(騒音)回避学習を課題とした実験を行った.コントロール不能性の操作により,事後の学習が阻害されるという典型的な学習性無力感現象が生起した.このとき,急性ストレスにより唾液中の分泌型免疫グロブリンA(s-IgA)量は一過性に増加したが,増加の度合いはコントロール不能な場合に,コントロール可能な場合に比較して顕著に大きかった.内分泌系指標である唾液中コルチゾールは変動せず,s-IgAが自律神経系を介するものである可能性が示唆された.
    2 平成13年度には,時間圧を伴う暗算を課題とした実験を行なった.この課題でもs-IgA量は一過性に増加したが,やはり増加の度合いはコントロール不能な場合に顕著に大きかった.
    いずれの実験においても,被験者自身のコントロール可能性の評定は不正確なものであったことに注目すべきである.すなわち,末梢における免疫系は,中枢におけるコントロール可能性の自動的な知覚により,なかば自動的に制御されていることが示唆された.今後,そうした制御メカニズムをより詳細に検討する必要があろう.

    1.本研究は、瞬目反射とその先行刺激による抑制効果の現象を、人間の情報処理過程を検討するプローブ刺激指標として用い、これによって感情と認知の関連を探究する新たな方法を開発することを目的とした。
    2.実験I.では言語を先行刺激とした場合の瞬目反射の抑制について検討した。言語の意味にかかわらず、これを反射誘発音声刺激(100dBの純音)より100〜300ms前に呈示すると瞬目反射量は約半分に抑制されることが明らかになった。1s以上前の呈示では抑制効果はみられなかった。
    3.実験II.では、被験者をあらかじめ快あるいは不快の感情状態に誘導した上で、快及び不快の意味を持つ単語を先行刺激として用い、瞬目反射の抑制効果を検討した。快感情の状態では、快単語呈示の場合に抑制が大きかった。これは単語認知時に快単語により注意が向けられたことを示している。いわゆる感情一致効果がみられた。一方不快感情状態では快単語、不快単語の間に抑制効果に差はみられなかった。
    4.瞬目反射は頑健で安定した現象であり、言語を先行刺激とした場合にも頑健な抑制効果がえられた。よってこの方法は認知過程の研究において有望な指標となりうると思われる。しかし、個人差の大きさ、順化過程の検討など残された問題も多い。今後、基礎的研究をさらに行う必要がある。
