OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

OBJECTIVES: The idea that perceived happiness may be associated with health and well-being is a recent topic of focus. 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.

Subjective and model-estimated reward prediction: Association with the feedback-related negativity (FRN) and reward prediction error in a reinforcement learning task Reviewed

INTERNATIONAL JOURNAL OF PSYCHOPHYSIOLOGY Vol. 78 ( 3 ) page： 273 - 283 2010.12

Language：English Publishing type：Research paper (scientific journal) Publisher：ELSEVIER SCIENCE BV

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.

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. Schroger, 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.

PERSONALITY AND INDIVIDUAL DIFFERENCES Vol. 49 ( 5 ) page： 451 - 456 2010.10

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. (C) 2010 Elsevier Ltd. All rights reserved.

Medial prefrontal cortex-dorsal anterior cingulate cortex connectivity during behavior selection without an objective correct answer

Nakao T., Osumi T., Ohira H., Kasuya Y., Shinoda J., Yamada J., Northoff G.

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.
