In chloralose-anaesthetized cats, the extracellular spontaneous unitary activity was recorded from 157 neurons, located in the medial oculomotor area. 98 units were identified as projecting onto the superior colliculus. Electrical stimulations of the contralateral claustrum provoked, on 13 of these cells, an excitatory effect, lasting 10-35 ms and appearing with a latency of 20-50 ms. Full length section of the corpus callosum totally abolished the contralateral claustrum effect. The results suggest that in the cat, the claustrum may have a role in the bilateral control of the visuo-motor performance.
在水合氯醛麻醉的猫中，从位于动眼神经内侧区的157个神经元记录到细胞外自发单位活动。其中98个单位被确定为投射到上丘。对侧屏状核的电刺激在其中13个细胞上引发了兴奋效应，持续10 - 35毫秒，潜伏期为20 - 50毫秒。胼胝体全长切断完全消除了对侧屏状核的效应。结果表明，在猫中，屏状核可能在视觉运动表现的双侧控制中发挥作用。
