Outline of Final Research Achievements

To investigate the beta-gamma synchrony of LFPs of bilateral MI of the two macaque monkeys during the bimanual tracking task, two 25-ECoG electrodes systems were set on the dura mater and long time recording were executed during the training period and the well trained period. Stronger beta　gamma synchrony were observed between right and left MI during the reward period of folding the position cursor in target area by both arms than other simultaneous moving period of arms. Reward or attentional neural system might modulate the beta gamma synchrony of bilateral MI cortices. On the contrary, such beta gamma synchrony in human EEG were difficult to observe during the same bilateral arm movement.
