[Inhibitory effect of the amygdala on alimentary-conditioned reflexes in the dog].

In experiments on dogs, changes of conditioned alimentary reflexes were studied under stimulation (50-100 mcA, 1, 40, 100 imp/s, 0.5 ms) of the basolateral area of amygdala before and after electrolytic ablation (5 mA, 60 s) of the head of the caudate nucleus. Stimulation of the amygdala, which elicited inhibition of conditioned secretory reflexes and prolongation of latencies in intact dogs leads to opposite - activating - influences after destruction of the caudate nucleus head. A conclusion is made on the participation of neurophysiological and neurochemical mechanisms of the caudate nucleus in transmission of inhibitory effects of the amygdala on alimentary conditioned reflexes.
