| Outline of Final Research Achievements |
The present study investigated the effect of differential bimanual movement on the activation of the sensorimotor cortex. We compared somatosensory evoked magnetic fields elicited by stimulation of the right index finger in four different conditions: control, unimanual movement, symmetric bimanual movement and asymmetric bimanual movement. The results revealed that the activity of the temporal and parietal areas corresponding to the primary somatosensory cortex (SI) and the secondary somatosensory cortex (SII) in the symmetric bimanual movement condition was significantly larger than that in other conditions. SI and SII are known to play an important role in sensorimotor integration. Therefore, we suggest that bimanual symmetric movement may easily extract somatosensory information.
