Anatomic and electrophysiologic evidence suggests there is a vestibular input to eye movement-related pause neurons in the midline of the pontine reticular formation of the cat. The present investigation sought to explore the functional significance of this vestibular drive by examining pause neuron response to horizontal rotational stimulation as cats were anesthetized with halothane or went into natural light sleep. Anesthesia unmasks the vestibular input to pause neurons in that during anesthesia, pause neurons continue to fire but their firing rate is modulated by vestibular stimulation. The particular response patterns of pause neurons to anesthesia are not uniform. We suggest that the results observed could be explained if pause neurons received input from both vestibular nuclei, either directly or possibly via the prepositus hypoglossi.
解剖学和电生理学证据表明，猫脑桥网状结构中线处与眼球运动相关的暂停神经元存在前庭输入。本研究旨在通过检查猫在接受氟烷麻醉或进入自然浅睡眠状态时，暂停神经元对水平旋转刺激的反应，来探索这种前庭驱动的功能意义。麻醉揭示了前庭对暂停神经元的输入，因为在麻醉期间，暂停神经元继续放电，但其放电频率受前庭刺激调节。暂停神经元对麻醉的特定反应模式并不一致。我们认为，如果暂停神经元直接或可能通过舌下前置核从前庭核接受输入，那么观察到的结果就可以得到解释。
