Role of the Premotor Cortex in Human Motor Activity

Abstract

Summary

The premotor cortex of man gives rise to bundles passing (1) to the premotor cortex of the opposite side and (2) through the internal capsule to thalamus, brain stem nuclei, and spinal cord. Interruption of this pathway alleviates the involuntary movements incident to disease of the basal ganglia. The interrelationships of terminals at the final-common-path are considered important in explaining the mechanism of these movements.
