The paper is devoted to the study of the neostriatum role in the mechanism of instrumental learning. In the experiments on cats with damaged dorsal segment of the caudate nucleus head, deficit of forming new instrumental reflexes and achieving complex tasks was revealed. Damage of the caudate neucleus had a most pronounced negative influence on the process of differentiation elaboration. High- and low-frequency stimulation of this structure in dogs did not disturb solution of an instrumental task: the end result was achieved, but the characteristics of many parameters of the motor act--latency, amplitude, duration--were significantly changed. The presented facts suggest that the basal ganglia play functionally different roles in the period of formation of instrumental conditioned reflexes and in the period of realization of consolidated connections. Possible mechanisms of neostriatum participation in the processes of elaboration and realization of instrumental reflexes of various motivational value are discussed.
本文致力于研究新纹状体在工具性学习机制中的作用。在对尾状核头部背侧段受损的猫进行的实验中，发现形成新的工具性反射和完成复杂任务存在缺陷。尾状核受损对分化过程产生了最明显的负面影响。在狗身上对该结构进行高频和低频刺激并未干扰工具性任务的解决：最终结果得以实现，但运动行为的许多参数特征——潜伏期、幅度、持续时间——发生了显著变化。所呈现的事实表明，基底神经节在工具性条件反射形成期和巩固连接实现期发挥着功能不同的作用。讨论了新纹状体参与具有不同动机价值的工具性反射的形成和实现过程的可能机制。
