[Role of acetylcholinergic structures of the caudate nucleus in mechanisms of inhibition of a conditioned food-getting reflex in the cat].
The effect of acetylcholinergic structures stimulation on the acquisition and inhibition of a conditioned food-procuring reflex was studied in cats. Physostigmine injections (0.1 mg/kg) did not facilitate the extinction of the non-reinforced food-procuring reactions of caudatectomized cats in contrast to the intact or lobectomized ones. The conclusion is made that acetylcholinergic structures of the caudate nucleus play an important role in the central inhibitory mechanisms responsible for the extinction of nonreinforced reactions.
