Lateral reticular nucleus mossy fibers

Other parts of the medial nucleus receive their mossy fiber collaterals from the lateral reticular nucleus (Kunzle, 1975 Russchen et al., 1976) and the spinal cord (Matsushita and Ikeda, 1970). The ventral, parvicellular part of the medial nucleus is located at the base of the lobules IX and X. 

CGRP-containing neurons were double-labelled with HRP from injections in the cerebellum of the cat in the lateral reticular nucleus, the external cuneate nucleus, the descending vestibular nucleus and in the lateral and ventral divisions of the basilar pons (Bishop, 1992). The origin of a major contingent of CGRP-immunoreactive mossy fibers from the pontine nuclei may explain their preferential distribution to the cerebellar hemisphere.
