Comparative study of cerebral cortical potentials associated with voluntary movements in monkey and man

Abstract

Eight monkeys (Macaca mulatta) were taught to squeeze and release a handgrip. The movement simulated the brisk squeeze of a hand dynamometer performed by 7 human subjects. Monkey. During the performance of the voluntary movements, slow cortical potentials (motor potentials or MPs) were studied with monopolar, surface bipolar, transcortical and intracortical recordings. A survey of the dorsal expanse of cerebral cortex showed that the contralateral motor hand area, somatosensory hand area and area 6 adjacent to the supplementary motor area became active with movement. MPs also were seen in the motor and somatosensory cortex medial to the hand area, but we concluded that those potentials were probably related to adventitious movements in the arm and leg. That area 6 became active with movement was further verified with extracellular unit recording; the behavior of area 6 units was compared with that recorded from units in the motor hand area. Using simultaneous transcortical recordings a sequence of cortical activation was observed in those areas generating an MP. The motor hand area became active first, followed in turn by area 6 and the somatosensory hand area. The monosynaptic cortico-cortical connections of the motor hand are...Continue Reading

Barrel cortex

Here is the latest research on barrel cortex, a region of somatosensory and motor corticies in the brain, which are used by animals that rely on whiskers for world exploration.
