| Outline of Final Research Achievements |
To specify roles of higher-order motor areas in controlling hand movements, we recorded neuronal activity and local field potentials (LFPs) from macaques while they performed a button-press task with the right or left hand. We found that the caudal cingulate motor area (CMAc) controls contralateral and ipsilateral hand movements in a counterbalanced fashion, whereas the supplementary motor area (SMA) preferentially controls contralateral hand movements. We also found that the rostral cingulate motor area (CMAr) and pre-supplementary motor area (pre-SMA) are more involved in sequential movements than CMAc and SMA.
