The afferent and efferent connections of the cerebellar interpositus complex were studied in a capuchin monkey (Cebus apella) that had received a transcannular horseradish peroxidase implant into the caudal portion of the anterior interpositus nucleus and posterior interpositus nucleus. While the heaviest anterogradely labeled ascending projections were observed to the contralateral ventral posterolateral nucleus of the thalamus, pars oralis (VPLo), efferent projections were also observed to the contralateral ventrolateral thalamic nucleus (VLc) and central lateral (CL) nucleus of the thalamic intralaminar complex, magnocellular (and to a lesser extent parvicellular) red nucleus, nucleus of Darkschewitsch, zona incerta, nucleus of the posterior commissure, lateral intermediate layer and deep layer of the superior colliculus, dorsolateral periaqueductal gray, contralateral nucleus reticularis tegmenti pontis and basilar pontine nuclei (especially dorsal and peduncular), and dorsal (DAO) and medial (MAO) accessory olivary nuclei, ipsilateral lateral (external) cuneate nucleus (LCN) and lateral reticular nucleus (LRN), and to a lesser extent the caudal medial vestibular nucleus (MVN) and caudal nucleus prepositus hypoglossi (NPH), and dorsal medullary raphe. The heaviest retrograde labeling was corticonuclear Purkinje cells in the paramedian cerebellar cortex lateral to the vermis of lobules IV-VIII. Otherwise, retrogradely labeled sources of afferents were predominantly contralateral in the dorsal, dorsomedial, paramedian, and peduncular sectors of the basilar pons, NRTP, and dorsal accessory (DAO) and medial accessory (MAO) of olivary nuclei, but were predominantly ipsilateral in the LCN, LRN, and in the medullary reticular formation along the roots of the hypoglossal (XII) cranial nerve. It appeared that the connections with the contralateral dorsal basilar pons, NRTP, DAO and MAO, and ipsilateral LCN and LRN are reciprocal.(ABSTRACT TRUNCATED AT 250 WORDS)
在一只卷尾猴（僧帽猴）中研究了小脑间位复合体的传入和传出连接，该猴接受了经套管将辣根过氧化物酶植入前间位核和后间位核的尾部。虽然观察到向对侧丘脑腹后外侧核嘴侧部（VPLo）的顺行标记的上行投射最重，但也观察到向对侧丘脑腹外侧核（VLc）和丘脑板内核复合体的中央外侧（CL）核、大细胞（以及较小程度的小细胞）红核、达克谢维奇核、未定带、后连合核、上丘外侧中间层和深层、背外侧导水管周围灰质、对侧脑桥被盖网状核和基底脑桥核（特别是背侧和脚桥核），以及背侧（DAO）和内侧（MAO）副橄榄核、同侧外侧（外部）楔核（LCN）和外侧网状核（LRN），以及较小程度的尾侧内侧前庭核（MVN）和尾侧舌下前置核（NPH），还有延髓背侧缝际核的传出投射。逆行标记最重的是位于小叶IV - VIII蚓部外侧的旁正中小脑皮质中的皮质核浦肯野细胞。此外，逆行标记的传入源在基底脑桥的背侧、背内侧、旁正中及脚桥部分、NRTP以及橄榄核的背侧副核（DAO）和内侧副核（MAO）中主要是对侧的，但在LCN、LRN以及沿舌下（XII）脑神经根部的延髓网状结构中主要是同侧的。似乎与对侧背侧基底脑桥、NRTP、DAO和MAO以及同侧LCN和LRN的连接是相互的。（摘要截断于250字）
