应用辣根过氧化物酶（HRP）逆行轴突运输法研究了猫前庭核向小脑的传入投射。HRP注射后前庭核内标记细胞在小脑不同部位的分布表明，前庭内侧核和降核的前庭神经元以及f和x细胞群向两侧投射到整个小脑蚓部、小叶、小脑顶和小脑顶，小脑顶核和前、后间位核。此外，标记细胞（巨大，中型和小型）一致发现双侧上级和外侧前庭核HRP注射后，在结节，绒球，顶核，并在蚓部大注射。HRP注射后，在小脑旁正中小叶、小脑旁小叶、小脑侧核、小脑背目前的研究结果表明，次级前庭小脑纤维项目在小脑更大的地区，起源于更多的细分和细胞群的前庭核复合体比以前已知的。
SummaryDetails of cerebellar afferent projections from the vestibular nuclei were investigated by the method of retrograde axonal transport of horseradish peroxidase (HRP) in the cat. The distribution of labeled cells in the vestibular nuclei following HRP injections in various parts of the cerebellum indicates that vestibular neurons in the medial and descending nuclei and cell groups f and x project bilaterally to the entire cerebellar vermis, the flocculus, the fastigial nucleus and the anterior and posterior interpositus nuclei. In addition, labeled cells (giant, medium and small) were consistently found bilaterally in the superior and lateral vestibular nuclei following HRP injections in the nodulus, flocculus, fastigial nucleus, and following large injections in the vermis. No labeled cells were observed in cases of HRP injections in crus I and II, the paramedian lobule, paraflocculus and lateral cerebellar nuclei. The present findings indicate that secondary vestibulocerebellar fibers project to larger areas in the cerebellum and originate from more subdivisions and cell groups of the vestibular nuclear complex than previously known.
