Microinjections of carbachol (carbamylcholine chloride) into the amygdaloid complex of rats produced behavioral and electrophysiological seizures which subsided within 24 hours. A persisting functional change caused a deficit in avoidance learning 1 to 3 weeks after the seizure. A cholinergic system is implicated by the fact that cholinergic blockade (scopolamine) of the amygdala during training reversed the effects of the seizures induced by carbachol.
