The brainstem mossy-fiber projections to lobules VIa, VIb,c, VII and VIII of the cerebellar vermis were studied by retrograde transport of horseradish peroxidase in the rat. The distribution of labeled cells indicated that these lobules received major projections from topographically different locations of the basilar pontine nuclei and the nucleus reticularis tegmenti pontis. Lobules VIa and VIII received an additional strong projection from the lateral reticular nucleus. Moderate projections were found to reach lobule VIa from the raphe pontis and external cuneate nucleus; lobules VIb,c from the raphe pontis, lateral reticular nucleus, and a group of cells in the lateral tegmentum; lobule VII from the spinal vestibular nucleus and a lateral tegmental cell group; and lobule VIII from the medial and spinal vestibular nuclei, nucleus intercalatus and Roller of the perihypoglossal nuclei, and the main cuneate nucleus. The quantitative and topographical differences in the origin of mossy fibers suggest that these lobules may subserve slightly different functions.
采用辣根过氧化物酶逆行运输法，在大鼠中研究了脑干苔藓纤维向小脑蚓部第VIa、VIb、c、VII和VIII小叶的投射。标记细胞的分布表明，这些小叶接受来自脑桥基底部核团和脑桥被盖网状核不同拓扑位置的主要投射。第VIa和VIII小叶还接受来自外侧网状核的额外强投射。发现中缝脑桥核和楔外核有中度投射至第VIa小叶；第VIb、c小叶接受来自中缝脑桥核、外侧网状核以及外侧被盖一群细胞的投射；第VII小叶接受来自脊髓前庭核和外侧被盖细胞群的投射；第VIII小叶接受来自内侧和脊髓前庭核、舌下神经周核的中间核和罗勒核以及主要楔核的投射。苔藓纤维起源的数量和拓扑差异表明，这些小叶可能具有略有不同的功能。
