| Outline of Final Research Achievements |
First, we found that the number of repetitive practices of post-learning of visual tracking task which requires the error correction is strongly related to the changes in motor cortex (M1) excitability and the retention of the motor learning. Second, we investigated the effect of intervention using an invasive brain stimulation, paired associative simulation (PAS), on the maximum voluntary contraction (MVC) and the maximum acceleration during ballistic abduction movement of an index finger. temporal increase of motor evoked potential (MEP) amplitude after PAS intervention was confirmed, and also, temporal increase of MVC was detected. However, the maximum acceleration was not affected by the PAS intervention. It is suggested that the intervention using an invasive brain stimulation possibely affects the fundamental motor performance.
