为了提供与丘脑中的C_1神经代表有关的信息，在猫丘脑的腹基底部复合体中记录了C_1神经和三叉神经诱发电位。电刺激对侧颈1神经和三叉神经上颌支可引起多相正负反应，平均最大正峰潜伏期分别为2.2ms和2.7ms。同侧刺激未能引起丘脑反应。等电位等值线图显示，刺激对侧C1神经和三叉神经的活动灶分别位于腹后内侧核(VPM)的背外侧段和腹内侧段。
In order to provide information pertaining to the C1nerve representation in the thalamus, C1nerve- and trigeminal-evoked potentials were recorded throughout the ventrobasal complex of the cat thalamus. Contralateral electrical stimulation of the C1nerve 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 C1nerve and trigeminal stimulation were located in the dorsolateral and ventromedial sections of ventroposterior medial nucleus (VPM), respectively.
