[Hypothalamic modulation of baroreceptor inhibition of the electrical activity in the renal nerve].

Changes in the renal nerve sympathetic activity in response to electrical stimulation of posterior hypothalamus and vago-aortic nerve were studied in acute experiments on cats. It was shown that stimulation of certain points in hypothalamus defence area led to the suppression of baroreceptor reflex-mediated inhibition of the renal nerve sympathetic activity. Chloralosa depressed hypothalamic modulation of baroreceptor reflexes.
