用Nauta银法研究了猫间质、齿状核和尾尖核近全损毁后的退行性变。传出的间位通路通过上脚离开小脑，与臂交叉完全交叉，形成上肢和下肢。较小的降支完全终止于被盖网状核和邻近的梯形核。上肢终止于下列中脑和间脑核团：被盖网状结构、红色、后连合、中央灰质、Edinger-Westfall、束旁、中央正中核、腹后内侧核、腹内侧核、腹侧核、外侧后核、腹后外侧核、网状核、腹前核、前外侧核、下丘脑背外侧核。齿状投射，不包括核的腹外侧部，也有类似的终末野，但范围略小。从两个核到同侧延髓的小而明确的投射通过网状小体。各顶核有三条投射通路，分别位于同侧视网状小体的直接小脑顶球束、对侧视网状小体的间接小脑球束(钩状束)和交叉臂结膜内至中脑和丘脑的小束。顶肌尾侧部分参与所有三个径路，吻部仅参与前两个径路。这些途径的核终止已经在以前的一篇论文中描述过。
Degeneration following near total lesions in interposed and dentate nuclei and in caudal fastigius was studied with Nauta silver method in the cat.. The efferent interpositus pathway leaves the cerebellum via the superior peduncle, crosses entirely in decussation of the brachium and forms ascending and descending limbs. The smaller descending limb terminates entirely in tegmental reticular nucleus and adjacent trapezoid nuclei. The ascending limb terminates in the following mesencephalic and diencephalic nuclei[long dash]tegmental reticular formation, ruber, posterior commissure, central gray, Edinger-Westfall, para-fascicular, centromedian, ventral posteromedial, ventral medial, ventral lateral, lateral posterior, ventral posterolateral, reticular, ventral anterior, H1 of Forel, and dorsolateral hypothalamus. The dentate projection, excluding the ventrolateral part of the nucleus, has a similar but somewhat less extensive terminal field. There are small but definite projections from both nuclei to the medulla of the same side via the restiform body. Each fastigial nucleus has three pathways of projection [long dash]direct fastigiobulbar tract in ipsilateral restiform body, indirect fastigiobulbar tract (uncinate fascicles) in contralateral restiform body, and a tract in the crossed brachium conjunctivum to the midbrain and thalamus. The caudal part of fastigius contributes to all three paths, rostral part only to first two paths. Nuclear terminations of these pathways have been described in a previous paper.
