Abstract

In anesthetized squirrel monkeys vestibular representation in the thalamus and basal ganglia was determined by field potential recording using peripheral electrical vestibular nerve stimulation. Vestibular thalamic regions were investigated for cortical connections. Two relatively large thalamic areas, nucleus ventralis posterolateralis, VPL and the posterior nuclear group (Po) received vestibular inputs with short latencies suggesting direct connections with the vestibular nuclei. Antidromic stimulation of the area 3 a vestibular field did not produce responses in any of the vestibular thalamic fields. The vestibular regions in VPL and Po can be antidromically invaded from SI and the anterior parietal lobe respectively. In the striatum vestibular fields were found in the suprathalamic portion of the nucleus caudatus and dorsomedially in the putamen.

摘要

在麻醉的松鼠猴中，通过使用外周电刺激前庭神经记录场电位来确定丘脑和基底神经节中的前庭表征。研究了前庭丘脑区域的皮质连接。两个相对较大的丘脑区域，即腹后外侧核（VPL）和后核群（Po），接受了潜伏期较短的前庭输入，这表明它们与前庭核有直接连接。对3a区前庭场的逆向刺激在前庭丘脑的任何场中均未产生反应。VPL和Po中的前庭区域可分别从体感皮层（SI）和顶叶前部被逆向侵入。在纹状体中，在前尾状核的丘脑上部和壳核的背内侧发现了前庭场。
