Single vestibular neurons functionally identified as secondary neurons receiving primary afferents from the horizontal canal in the cat were intracellularly stained with horseradish peroxidase (HRP). The vestibular neurons projecting to the ipsilateral abducens nucleus distributed terminal branches in a relatively narrow band in the nucleus. The stem axon of contralaterally projecting vestibular neurons bifurcated into ascending and descending branches in the contralateral medial longitudinal fasciculus. The collaterals emerging from these branches distributed terminals in a relatively wide area in the abducens nucleus. Collateral branches extended into the medial vestibular nucleus, prepositus hypoglossi nucleus and reticular formation.
用辣根过氧化物酶（HRP）对功能上被确定为接受来自猫水平半规管初级传入纤维的二级神经元的单个前庭神经元进行细胞内染色。投射到同侧展神经核的前庭神经元在该核内以相对较窄的带分布终末分支。对侧投射的前庭神经元的轴突干在对侧内侧纵束中分为升支和降支。从这些分支发出的侧支在展神经核内相对较宽的区域分布终末。侧支延伸到内侧前庭核、舌下前置核和网状结构。
