| Outline of Final Research Achievements |
Bimanual movement had been considered to be simply composed right and left manual movements. However, behavioral research of motor leaning demonstrated the same arm is supported by partially overlapping neural processes for unimanual and bimanual movements. This results suggested existence of the specific neural processes for bimanual movement. Here, we investigated the neural processes for unimanual and bimanual movement to evaluate corticospinal excitability during unimanual and bimanual force exertion with transcranial magnetic stimulation over motor cortex.
We confirmed that contralateral manual force exertion of the particular orientation changed the unimanual corticospinal excitability. Moreover, the changes of corticospinal excitability had the asymmetric property. Right manual force exertion facilitated left manual corticospinal excitability, while left manual force exertion inhibited right manual one.
