The cerebellum is involved in eye movements and in the coordination of head and eye movements through its influence on the vestibular and other brainstem nuclei. Part of this control is via the fastigial nuclei, the most medial of the deep cerebellar nuclei. One projection bundle from the fastigial nucleus is the uncinate fasciculus \(white\). It crosses within the cerebellum and loops over the superior cerebellar peduncle to reach the brainstem. Another bundle containing uncrossed \"fastigiovestibular\" fibers \(yellow\) simply exits the cerebellum via the juxtarestiform body \(a tract just medial to the inferior cerebellar peduncle and sometimes included as part of it\). The arrows \(black\) indicate the direction of the fibers, from the fastigial nuclei to the brainstem. These fastigial projections end mostly in the inferior and lateral vestibular nuclei, and in several brainstem reticular nuclei. Note also that all the vestibular nuclei receive direct ipsilateral projections \(not shown\) from the cerebellar cortex of the vestibulocerebellum \(the flocculonodular lobe and parts of the vermis\)."))
