| Research Abstract |
The aim of this study is to investigate details of the difficulty on restarting a movement just after the sudden stop. First, we investigated the performance of go/stop/re-go task and found stop-and-restart difficulties after a short (~100 ms) and longer (>200 ms) stop-to-restart interval (SRSI). In order to investigate the underlying mechanisms, we conducted 2 neurophysiological experiments: TMS and surface-EEG recordings. As a result, we demonstrated that stop-and-restart difficulty with short SRSIs might be associated with a stop-related suppression of corticomotor excitability and alpha-band EEG phase locking to re-Go-signal visual perception weakened in the delayed re-Go response trials with long SRSIs
