Abstract

Chronic experiments were carried out on 19 adult cats after preliminary division of the brain stem at the level of the anterior border of the superior colliculus. High-frequency electrical stimulation of the posterior hypothalamus of these animals caused desynchronization of electrical activity in different parts of the neocortex. The influence of the posterior hypothalamus was predominantly on activity in the frontal zones of the neocortex. It is postulated on the basis of these results that the posterior hypothalamus has an activating effect on the neocortex through the thalamic nuclei.
