| Outline of Final Research Achievements |
When humans normally move their bodies, they get sense of agency (the subjective awareness that one is excusing and controlling one’s own actions) and sense of body ownership (the awareness that one is the owner of an action or movement). Senses of agency and body ownership constitute bodily self-awareness. Our research project found that neural substrates for bodily self-awareness mainly exist in neural networks connecting the inferior parietal lobe and the inferior frontal gyrus in the right cerebral hemisphere. This finding was obtained by our behavioral experiments, measurements of brain activity, and non-invasive brain stimulation in normal human subjects as well as our analysis of neural networks in schizophrenic patients with altered bodily self-awareness. We also revealed neural mechanisms of sensory suppression, which is the basis of bodily self-awareness, by recoding activity of individual neurons in monkeys.
