| Outline of Final Research Achievements |
In sports settings, people are often required to perform movements that they are unprepared for, owing to continuously changing circumstances. This study examined the neural mechanisms associated with rapid adjustment of interceptive actions in response to inter-trial changes in target velocity. The main findings were as follows: 1) the rapid adjustment of brief interceptive actions completed within 350 ms was accomplished by using predicted sensory consequence of movement (pSCM) information; 2) the pSCM information for rapid adjustment was generated in the supplementary motor area just prior to movement onset; 3) after movement onset, the supplementary motor area did not play an important role in the rapid adjustment of interceptive actions.
