Abstract

The connections between the claustrum and the contralateral motor areas were electrophysiologically investigated in cats under chloralose anesthesia. The extracellular unitary activity of 81 pyramidal tract neurons (PTNs) was recorded; 22 PTNs were inhibited by activation of the contralateral claustrum; inhibition was preceded by an early activation of 4 out of the 22 inhibited PTNs. Section of the corpus callosum abolished the contralateral claustrum effect, while the action of the ipsilateral homologous structure persisted.

摘要

在水合氯醛麻醉的猫身上，用电生理学方法研究了屏状核与对侧运动区之间的联系。记录了81个锥体束神经元（PTN）的细胞外单位活动；22个PTN受到对侧屏状核激活的抑制；在这22个受抑制的PTN中，有4个在抑制之前出现早期激活。胼胝体切断消除了对侧屏状核的作用，而同侧同源结构的作用仍然存在。
