| Research Abstract |
MEG recordings were performed to investigate the activation of the premotor and somatosensory cortexes following voluntary movement. In this study, we used the electrical motor point stimulus and mechanical tactile stimulus with voluntary movement. As results, we clarified that the first component of the movement evoked magnetic field (MEF) was elicited by the activity of muscle spindle following muscular contraction. In addition, it was considered that the second component of MEF might be occurred by the changes in the displacement of the skin according to voluntary movement.
