Abstract

Evoked potentials in response to a combination of electrostimulation of both anterior extremities were investigated under conditions of a chronic experiment on monkeys in the head of the caudate nucleus and frontal and somatosensory cortex. Three types of interaction of afferent volleys evoked by spontaneous stimulation were noted: facilitation, summation, and depression. A high degree of correlation of the responses in the head of the caudate nucleus with the responses in the frontal cortex was noted. The role of the frontal and somatosensory cortex in the formation of sensory responses in the caudate nucleus is compared.
