e of the medulla oblongata. Almost all of these passthrough the corpus restiforme. The most important layer is the cerebellarolivary tract. This probably arises from the hemispheres of the cerebellum,the fibers passing arc-like through the posterior olives and the secondary olivesof the same side to the nuclei of the olives and secondary olives of the oppo-site side (Figs. 109, 110). Some of the fibers which pass from the cerebellum through the corpusrestiforme to the medulla reach the sensory nuclei, the glosso-pharyngeal-vagus, and the trigeminal. They originate in the middle portion of the cere-bellum, probably in the nucleus tegmenti. Another important fiber tract which originates in the cerebellum is that 108 HISTOLOGY OF THE CENTRAL NERVOUS SYSTEM of the peduncles to the pons. They form that cerebellar fiber system in thepons which passes from unknown regions in the hemispheres of the cere-bellum to the cortex, first entering the ventral portions of the pons and encir- FCocu/t/^

Many nerve-cellsin which a portion of the fibers appears to end are here deposited, while, onthe other hand, fibers of these cells ascend to the cerebellum, probably in thesame tract. Some of these fibers, however, extend to the raphe of the pons, NEURON SYSTEMS AND NEURON DISEASES 109 which they partially cross, and then pass dorsally to the region of the teg-mentum where they may be traced toward the cerebrum.
