Outline of Final Research Achievements

Social brain makes sound social mind based on cooperative social adjustment between the self and the others in our society. Social brain can be defined as a neuronal basis for binding self and others in a purpose-oriented behavior in the social context and therefore social mind has its related neuronal representation. We investigated how the sound mind being cultivated in the sound social brain, from monkey to human levels, in terms of various prefrontal brain’s (PFC) executive functions. We aimed to study PFC, specifically, in terms of its neuronal control of social cooperation, relation to social adjustment disorder, interaction of working memory and social brain, and related modeling. To test the issues, we measured from single neuronal activity to whole brain activity under various tasks using functional magnetic resonance imaging (fMRI), functional near-infrared spectroscopy (fNIRS).
