[Effect of the orbitofrontal area of the cat cerebral cortex on the resistance of the supraoptical nuclei of the hypothalamic region under ftorotan anesthesia].

Acute experiments have shown that as ftorotan anesthesia is enhanced, the supraoptical nucleus of the hypothalamic area deprived of the effect of the orbitofrontal zone of the cerebral cortex gets less resistant to ftorotan than the analogous nucleus experiencing the influence of the cortical zones. The greatest resistance to ftorotan anesthesia was displayed by the orbitofrontal zone of the cortex. In the course of the animals' egress from anesthesia, the bioelectrical activity got recovered in the following way: first in the orbitofrontal zone of the cortex, then in the supraoptical nuclei of the hypothalamic area that retained the influence of the cortex, and, finally, in the supraoptic nuclei deprived of the subordination effect of the cortex.
