We placed 26 electrodes on the scalp overlying the sensorimotor area and recorded corticalpotentials related to abduction of the index finger.

We studied the scalp-recorded, movement-related corticalpotentials occurring immediately before and after the onset of movement in 5 patients with asymmetric Parkinson's disease.

Saccade characteristics and mean amplitudes of slow corticalpotentials time-locked to peripheral target were analyzed in 23 healthy volunteers and 19 schizophrenic patients.
