Stimulation of the medial amygdaloid nucleus (AME) produces a long-latency and long-lasting inhibition of pyramidal cells in both the dorsal and the ventral hippocampus. The inhibition is blocked by a specific antagonist to vasopressin, which is a candidate neurotransmitter in the system. Antidromic activation of the AME from the hippocampus occurs with a latency suggestive of the conduction velocity of small diameter unmyelinated fibers. Immunocytochemistry for vasopressin reveals small… CONTINUE READING
