Effect of some cholinergic drugs on the conditioned pole jump response in rats.
Rats were trained to pole jump to a buzzer as the conditioned response. Cholinergic agents, oxotremorine and physostigmine significantly depressed this response. The effect was blocked by atropine. Nicotine and carbachol failed to modify the conditioned pole jump response. It is suggested that the central muscarinic inhibitory receptors are involved in the action of these drugs.
