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.

Journal of Positive Psychology Vol. 3 ( 3 ) page： 192 - 201 2008.7

Language：English Publishing type：Research paper (scientific journal)

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.

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.

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.

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 O-15-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.

Sleep processes in good sleeper and poor sleeper

Journal of Human Environmental Studies Vol. 6 ( 2 ) page： 57 - 63 2008

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Society for Human Environmental Studies

In this study, we investigated sleep profiles in good sleeper and poor sleeper classified by subjective report of daily sleep state. Auditory evoked potentials (AEP), N300 and N550, were measured in order to clarify the relationship between modulation of arousal level and attentional system during sleep. Six healthy undergraduate students participated in this experiment. Based on a questionnaire of sleep latency, three subjects with easy sleep initiation (good sleeper: GS, > 20 minutes) and another three subjects with difficult sleep initiation (poor sleeper: PS, < 30 minutes) were selected. We conducted three nights' experiments after one night sleep for habituating to experimental environment: the first night is control condition, the second night is the first stimulation condition, and the third night is the second stimulation condition. The stimulus used in this study was pure tone (60dB, 1000Hz) lasting 0.1 sec at 10 sec SOA. The sleep polygraph was recorded in all condition, and AEP was also recorded in two stimulation conditions. The data until the end of the first sleep cycle were analyzed. As the result, we observed that sleep latency was shorter and the appearance rate of deep sleep was lower in GS group compared to PS group. In addition, greater N550 amplitude in GS group suggests that subjects in GS group strongly pay attention to stimulus from outwards. Therefore we revealed the possibility that GS group has difficulty to maintain deep sleep by hyperactivity of attentional system, although the sleep latencies of GS group subjects were short.

Emotional process at times goes awry. For instance, depersonalization disorder includes emotional detachment, which is evoked sometimes by stressful events, just like a common symptom of acute stress disorder. Similarly, psychopathy is characterized by weak emotional responses. However, although they appear to have something in common, these phenomena are not completely the same, and each has some different function for or influence on behavior. We investigated the differences between emotional detachment in depersonalization and weakened emotion in psychopathy, using Emotional Processing Scale (EPS). Path analysis revealed that emotional malfunctions in depersonalization could be separated into dissociation, which was common with primary psychopathy, and suppression, uncontrollability, and confusion, which were common with secondary psychopathy.
