| Outline of Final Research Achievements |
The aim of this research was to reveal how the brain process sensory feedback during self-generated hand action, which is functionally correlated with sense of agency. We examined activity of single neurons from primary somatosensory cortex of macaque monkeys during moving a lever that introduce brush movement. We introduced different time delays to the brush movement relative to the lever. This made error between the predicted and actual tactile sensory feedback. We found that certain number of neurons showed higher response with the degree of temporal delay in brush movement, while some other neurons showed less activation when the temporal delay was introduced. The results suggested that the primary somatosensory cortex modulated by corollary discharge and a part of network for sense of agency.
