Abstract

The influence of claustrum stimulation on spontaneous unitary activity of the ipsilateral frontal oculomotor area was analyzed in anesthetized cats. Sixty-five neurons were isolated, 37 of which (57%) were identified as projecting to the superior colliculus; on 12 of these last units (32%), electrical activation of the dorsal claustrum provoked an excitatory effect, which appeared after a latency of 5-15 ms and lasted 10-25 ms. These data could suggest the involvement of the claustrum in the visuomotor coordination function.

摘要

在麻醉猫中分析了屏状核刺激对同侧额叶动眼区自发单位活动的影响。分离出65个神经元，其中37个（57%）被确定为投射至上丘；在这37个神经元中的12个（32%）上，背侧屏状核的电激活引发了兴奋效应，该效应在5 - 15毫秒的潜伏期后出现，持续10 - 25毫秒。这些数据可能提示屏状核参与了视觉运动协调功能。
