Brachium conjunctivum

Fig. 103. The cerebellar nuclei of the cat. The transitional U-shaped region of the fastigial and posterior interposed nuclei is indicated by double hatching, be = brachium conjunctivum cr = restiform body DV = descending vestibular nucleus F = fastigial nucleus flo = floccular peduncle Ftail = tail of the fastigial nucleus lA = anterior interposed nucleus IP = posterior interposed nucleus L = lateral cerebellar nucleus LV = lateral vestibular nucleus MV = medial vestibular nucleus SV = superior vestibular nucleus u = uncinate tract Y = group y of Brodal and Pompeiano (1957).

The topography in the cerebellar nucleo-olivary projection has been studied in different mammalian species. The nucleo-olivary fibers from the interposed and lateral nuclei run in a separate tract, ventral to the brachium conjunctivum in cat (Legendre and Courville, 1987), rat (Cholley et al., 1989) and rabbit (Tan et al., 1995b). Fastigio-olivary...
