Continuous low frequency stimulation of the caudate nucleus by constant parameters leads to the appearance of a characteristic "caudate spindle" as well as other "inhibitory" electrophysiological responses (single unit activity intracellular recordings) varying in duration and amplitude in the cerebral cortex. Computerized data processing of the responses (amplitude and duration of individual spindles, numbers of single unit blocking and sizes of EPSP and IPSP) indicated increments and decrements appearing in stable and characteristic sequences. The same low frequency caudate stimulation produces fast bursts in the course of continuous stimulation. The variations and dynamic patterns of inhibitory caudate influences upon the cortex seem to be in equilibrium with the excitatory influences from the hypothalamus representing a unique regulatory system.
以恒定参数对尾状核进行连续低频刺激会导致出现特征性的“尾状纺锤波”以及其他“抑制性”电生理反应（细胞内记录的单个单位活动），这些反应在大脑皮层中的持续时间和幅度各不相同。对这些反应进行计算机化数据处理（单个纺锤波的幅度和持续时间、单个单位阻断的数量以及兴奋性突触后电位和抑制性突触后电位的大小）表明，稳定且特征性的序列中出现了增加和减少。相同的低频尾状核刺激在连续刺激过程中会产生快速爆发。尾状核对皮层的抑制性影响的变化和动态模式似乎与来自下丘脑的兴奋性影响处于平衡状态，代表了一个独特的调节系统。
