The specific character of the relationship of the baseline cellular activity of the caudate nucleus to the features of the impulse activity of the centrum medianum of the thalamus has been identified in chronic microelectrode experiments. Reciprocal changes in the bioelectrical activity were recorded in the first group of cells, with a low action potential repetition frequency, while unidirectional changes with reorganizations in the intralaminar nucleus were recorded in the second. The activation of the cells of the centrum medianum of the thalamus was accompanied during the formation of an instrumental conditioned defense reflex by the formation of a pattern of impulse activity in neurons of the neostriatum which coincided in sign with the reorganizations which were characteristic during the investigation of the baseline activity. It is hypothesized that the features of the internal structure of the caudate nucleus underlie such a relationship.
在慢性微电极实验中，已确定尾状核基线细胞活动与丘脑中央中核冲动活动特征之间关系的具体特性。在第一组细胞中记录到生物电活动的相互变化，其动作电位重复频率较低，而在第二组细胞中记录到在板内核中有重组的单向变化。在形成工具性条件防御反射过程中，丘脑中央中核细胞的激活伴随着新纹状体神经元冲动活动模式的形成，该模式在信号上与研究基线活动时的特征重组相一致。据推测，尾状核内部结构的特征是这种关系的基础。
