In the acute experiments on rabbits there was discovered an impulse activity of afferent and interneurons of the medullar cardiovascular center in the conditions of hypoxia and hypercapnia. Afferent neurons received information on myelinated fibers of vagus nerve and caused reaction on hypercapnia in one per three cases. Interneurons received information simultaneously on both myelinated and unmyelinated fibers of vagus nerves. They reacted both on hypoxia and hypercapnia.
