In this paper the results of investigations of the participation of caudate nucleus neurons in the decision-making process and the process of organization of the program of a future motor response during the performance by Macaca mulatta monkeys of a delayed spatial choice tasks of varying degrees of complexity are presented. The presence in the caudate nucleus of spatially selective neurons, which are subdivided into two groups, was established: the position of conditional signals is reflected in the activity of one of the groups, and the direction of the future motor response is reflected in the activity of the other. The decision-making process is reflected in the impulse activity of neurons of the head of the caudate nucleus in two of its aspects: as the formation or choice of a specific motor program (spatially selective activity) and as a transitional factor from the instructive to the executive phase of the behavior.
本文展示了对恒河猴在执行不同程度复杂的延迟空间选择任务时，尾状核神经元参与决策过程以及未来运动反应程序组织过程的研究结果。已确定在尾状核中存在空间选择性神经元，这些神经元可分为两组：条件信号的位置反映在其中一组的活动中，而未来运动反应的方向反映在另一组的活动中。决策过程在尾状核头部神经元的冲动活动中通过两个方面得以体现：作为特定运动程序的形成或选择（空间选择性活动）以及作为行为从指令阶段到执行阶段的过渡因素。
