Cerebellar fibers to the midbrain visuomotor areas were traced in the cat auto-radiographically after injections of tritiated amino acids into individual cerebellar nuclei. Fibers from the dentate (DN), anterior interpositus (AIN) and posterior interpositus (PIN) nuclei were distributed contralaterally, while those from the fastigial nucleus (FN) bilaterally. The FN fibers appeared to arise mainly from the caudal half of the FN. In the superior colliculus (SC), the FN or DN fibers were more numerous than the PIN fibers, and the areas of termination of the FN fibers were located more medially than those of the DN and PIN fibers. These cerebellotectal fiber terminals were in the intermediate and deep SC layers; clustering of terminal silver grains was noted in the FN and DN fibers-recipient areas in the intermediate gray layer. In the pretectum, the DN fibers terminated ventrally in the reticular part of the anterior pretectal nucleus and the posterior pretectal nucleus. THe AIN fibers terminated ventrally in the compact part of the anterior pretectal nucleus and the posterior pretectal nucleus. The nucleus of the posterior commissure received cerebellar fibers chiefly from the DN, and additionally from the FN. The nucleus of Darkschewitsch and the interstitial nucleus of Cajal received fibers from all cerebellar nuclei. No cerebellar fibers terminated in the extraocular motor nuclei and the Edinger-Westphal and anteromedian nuclei.
在将氚标记的氨基酸注射到猫的各个小脑核团后，通过放射自显影法追踪了小脑至中脑视觉运动区的纤维。来自齿状核（DN）、前间位核（AIN）和后间位核（PIN）的纤维呈对侧分布，而来自顶核（FN）的纤维则双侧分布。FN纤维似乎主要起源于FN的后半部。在上丘（SC）中，FN或DN纤维比PIN纤维更多，且FN纤维的终止区域比DN和PIN纤维的终止区域更靠内侧。这些小脑顶盖纤维终末位于SC的中间层和深层；在中间灰层的FN和DN纤维接受区可见终末银粒的聚集。在顶盖前区，DN纤维终止于前顶盖前核和后顶盖前核网状部的腹侧。AIN纤维终止于前顶盖前核和后顶盖前核致密部的腹侧。后连合核主要接受来自DN的小脑纤维，此外还接受来自FN的纤维。达克谢维奇核和 Cajal间质核接受来自所有小脑核团的纤维。没有小脑纤维终止于眼外肌运动核以及动眼神经副核和前正中核。
