[Influence of the hypothalamic nuclei on the electrical activity of neurons of the visual cortex].

Background and light-evoked activity of single neurons in the rabbit optic cortex was investigated before and after electrical stimulation of the anterior and posterior hypothalamic nuclei. No distinct reciprocity between the effect of the anterior and posterior hypothalamic areas on the optic cortex neurons was found. Long cyclic changes in the background rhythmic activity of the neurons were observed after stimulation of different hypothalamic nucleima modulating effect of these nuclei on the activity of the optic cortex neurons was also detected under conditions of retinal stimulation by repetitive light.
