Slow potentials preceding self-paced hand movements in the parietal cortex of monkeys.
In our previous paper, surface negative-deep positive slow potentials were reported to appear prior to self-paced hand movements in the premotor and the forelimb motor cortices of unanesthetized, freely moving monkeys, as recorded with the elctrodes implanted chronically in the cortices. The present study revealed that similar slow potentials were recorded also in the somatosensory cortex in most cases, but infrequently and unmarkedly in area 7, never in area 19.
