摘要
Event-related desynchronization (ERD) and recovery of EEG beta rhythms (15-26 Hz) were studied during slow and brisk self-paced index finger extension and flexion. beta rhythms started to recover earlier in brisk movements. Brisk movements showed no correlation between duration of EMG burst in the extensor muscle and the latency of recovery whereas slow movements did. In contrast to beta-ERD which was widespread, the recovery and rebound of beta rhythms occurred in a circumscribed focus close to the hand MI area.
