In order to provide information pertaining to the C1 nerve representation in the thalamus, C1 nerve- and trigeminal-evoked potentials were recorded throughout the ventrobasal complex of the cat thalamus. Contralateral electrical stimulation of the C1 nerve and maxillary division of the trigeminal nerve elicited multiphasic positive-to-negative responses with mean maximum positive peak latencies of 2.2 ms and 2.7 ms, respectively. Ipsilateral stimulation failed to elicit a thalamic response. Construction of isopotential contour maps revealed that the foci of activity elicited by contralateral C1 nerve and trigeminal stimulation were located in the dorsolateral and ventromedial sections of ventroposterior medial nucleus (VPM), respectively.
为了提供有关丘脑C1神经表征的信息，在猫丘脑的腹侧基底复合体中记录了C1神经和三叉神经诱发的电位。对C1神经和三叉神经上颌支进行对侧电刺激，分别引发了多相正到负的反应，平均最大正峰潜伏期分别为2.2毫秒和2.7毫秒。同侧刺激未能引发丘脑反应。等电位轮廓图的构建显示，由对侧C1神经和三叉神经刺激引发的活动焦点分别位于腹后内侧核（VPM）的背外侧和腹内侧部分。
