This paper reviews past research on bodily consciousness and its neural representations, as well as current research on the body, self, and brain. In the early 20th century bodily consciousness was first conceptualized as body schema and body image. Empirical findings on phenomena such as phantom limbs suggested that body consciousness could be reduced to body representations in the brain. Body schema and body image have firm foundations in related brain areas including somatosensory and motor cortices, although they cannot be completely reduced to neural processes. In addition, the body image can be better categorized into two aspects (body semantics and body topology) that correspond to different streams of neural processing. Finally, we explored the self that emerges through interactions between the sense of body ownership and the sense of agency. The subjective sense of the self could well be the result of the bottom-up integration of multiple body representations.

The purpose of the present study was to investigate reliability and validity of Japanese version of the Primary and Secondary Psychopathy Scales. First, similar to the original scales, exploratory factor analysis of the data from a sample of 475 revealed two factors for the scale items. In addition, a sample of 77 provided good indication of internal consistency as well as test-retest temporal stability. Correlations with BIS/BAS scales and PANAS also gave support for the scales' validity. These and other results suggested that, with some reservations, the Japanese version had usefulness of the original scales to measure psychopathic tendencies.

Depersonalization is considered to be elicited by traumatic stress, and is characterized by episodes of detachment or estrangement from one's self. Recently, this phenomenon was understood as a coping mechanism, reducing the impact of a traumatic event. But findings of previous empirical studies were not consistent, possibly because depersonalization has not been classified into more detailed, finer categories. In this study, we preliminarily investigated the classification scheme of Cambridge depersonalization scale using factor analysis, and the relationships between depersonalization and behavioral inhibition system (BIS). Results suggested that depersonalization might lead to reduced and maladaptive emotional responses.

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⁄hereditary prosopagnosia. The investigation on the congenital⁄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⁄hereditary prosopagnosia screening scale is the first step of the congenital⁄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⁄physiological responses on face stimuli. As a result, we found highly internal consistency and test-retest reliability for the Japanese version of the congenital⁄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.

Background: Brain activation areas in relation to bowel stimuli have been reported using brain imaging techniques in patients with irritable bowel syndrome(IBS). However, the results are controversial. The aim of this study is to clarify responsible brain site(s) when stimulated by the rectal balloon distension-induced abdominal symptom in IBS in terms of braingut interactions. Methods: Seven healthy volunteers and five patients with diarrhea-predominant IBS based on the Rome II criteria were recruited. All were right-handed men. Rectal sensitivity was examined with balloon distension using a barostat device. Studies are performed with or without rectal distension(RD). Each task took 4 minutes. The subjects were assigned to have each twice task at the individual pain threshold level with 11 minute intervals. The changes in brain blood flow were evaluated using H_2 ^<15>O-water positron emission tomography. Subjects were asked rectal pain and stress level with visual analogue scale(VAS) before and soon after the respective task. Blood pressure, heart rate, and several serum stress-related substances were also investigated. Results: The threshold of pressure for rectal pain was significantly lower in the IBS patients(IBS=14.4mmHg, volunteers=26.3mmHg on average). The IBS patients showed a significant increase in blood flow in especially insula, and in thalamus at RD as compared with that in volunteers. Analyzing changes in VAS score before and after task, an increase of score about physical stress was significantly larger in the IBS patients in RD although no differences was noted in pain perceived score among all subjects in RD. A tendency of correlation was observed between the RD-induced increment in blood flow in insula and that in VAS score of stress-feeling. Conclusions: The IBS patients had a significantly lower pain threshold against RD. Under RD stress at an individual pain threshold, a significant objective activation in insula, subjective physical stress, and correlation between them were obtained, indicating the brain activation magnitude-correlated stress in IBS.

In recent years, the importance of tactile stimulation/haptics has increased in various research fields. Psychologists and cognitive neuroscientists have great difficulty controlling tactile stimulation in experiments, in contrast to visual and auditory stimulation. Unlike studies involving audiovisual stimulation, there is no standardized tactile stimulation device, such as a computer display or speaker, which can be purchased anywhere and then controlled easily by any personal computer. In this article, methods of controlling tactile stimulation using vibration, electrical stimulation, and touch on the various materials are introduced. The methods introduced do not completely overcome the difficulty of controlling tactile stimulation in experiments; therefore, psychologists must expend further effort to develop a standardized method. More active collaboration with engineering/robotics researchers and commercial companies will play an important role in this standardization.

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.
