Research Abstract

The learning effect of a unimanual motor task (a grip force modulation) remained after a bimanual motor task, whereas that of a bimanual motor task disappeared after a unimanual motor task. These results were not consistent with that of a previous study by Nozaki et al.(2006). Current results suggest that the neural mechanism related to motor learning is different between hand and arm. The fMRI study suggested that the learning effect of a unimanual task was stored at the primary motor area.
