Abstract
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.
摘要
研究了乙酰胆碱能结构刺激对猫获得和抑制条件性食物获取反射的影响。与完整或切除叶的猫相比，注射毒扁豆碱（0.1mg/kg）并未促进尾状核切除猫非强化食物获取反应的消退。得出的结论是，尾状核的乙酰胆碱能结构在负责非强化反应消退的中枢抑制机制中起重要作用。
