Interaction of inferior olivary nucleus with reflex bradycardia and tachycardia in the cat.

Abstract

In chloralose-urethane anesthetized cats, stimulation of the ION, apart from directly producing cardioinhibition, was capable of interacting antagonistically with reflex tachycardia (induced by nitroglycerin) and synergistically with reflex bradycardia (induced by phenylephrine). The degree of the potentiation or antagonism was greater than the sum of the… (More)
