[Reactions of limbic cortex neurons to stimulation of the splanchnic and sciatic nerves and mammillary region of the hypothalamus].

The background and evoked activities of the limbic cortex neurons to electrical stimulation of the splanchnic and ischiatic nerves and the mammillary body of the hypothalamus were investigated in anesthetized cats. In the presence of effective convergence of sensory visceral and somatic volleys on the limbic cortex neurons low convergence of volleys from the central hypothalamic and peripheral sources was observed. Orthodromic and antidromic responses to the stimulation of the mammillary body were detected testifying to the existence of direct bilateral connections between the anterior limbic cortex and the mammillary body.
