Cerebellum Laboratory
LABORATORY OBJECTIVES
1. To know the origin, course, and termination of cerebellar afferent (spinocerebellar,
vestibulocerebellar, pontocerebellar, olivocerebellar) and efferent (cerebellorubral and
cerebellothalamic) pathways.
2. To identify in the Haines’ Neuroanatomy Atlas the location of deep cerebellar nuclei,
and other nuclei and tracts associated with cerebellar afferents and efferents.

Cerebellar vermis/cerebellar hemispheres
Anterior, posterior, and flocculonodular lobes of the cerebellum
Primary fissure/ pre-nodular (posterolateral) fissure- separate the three lobes
Nucleus dorsalis of Clarke/ dorsal spinocerebellar tract
Ventral spinocerebellar tract (enters cerebellum thru superior cerebellar peduncle)
Accessory (lateral) cuneate nucleus and cuneocerebellar tract (in inf. cerebellar peduncle)
Inferior cerebellar peduncle (restiform body, juxtarestiform body)- contains primarily
afferents (spinocerebellars, vestibulocerebellars, olivocerebellars)
8. Inferior olivary nucleus
9. Olivocerebellar tract (climbing fibers)
10. Vestibular complex/ flocculonodular lobe/ juxtarestiform body (vestibulocerebellars and
fastigiovestibulars)
11. Deep cerebellar nuclei (fastigial, globose, emboliform, dentate)
12. Basilar pontine nuclei and pontocerebellar fbers
13. Middle cerebellar peduncle (brachium pontis)- contains pontocerebellar fibers
14. Superior cerebellar peduncle (brachium conjunctivum)- contains primarily cerebellar
efferents from dentate, globose and emboliform nuclei; but also afferents: vent.
spinocerebellars)
15. Decussation of superior cerebellar peduncle (brachium conjunctivum)
16. Red nucleus (input from cerebellum and projects to contralateral spinal cord)
17. Ventrolateral nucleus of the thalamus
18. Central tegmental tract (contains rubro-olivary fibers and crossed desc. limb of the
superior cerebellar peduncle, containing cerebello- (dentato-)-olivary fibers)
