C Courses of the major cerebellar tracts through the brainstem

The cerebellum is involved in the coordination of movement. Descending tracts (red) and ascending tracts (blue) enter the cerebellum through the superior, middle, and inferior cerebellar peduncles.

Superior cerebellar peduncle: contains most of the efferent axons from the cerebellum (see p. 242). The only major afferent axon tract entering the cerebellum through the superior peduncle is the anterior spinocerebellar pathway.

Middle cerebellar peduncle: largest of the three peduncles, occupied mostly by afferent fibers from contralateral basal pontine nuclei. These afferent fibers are the second step of a massive descending cortico-pontine to ponto-cerebellar projection.

Inferior cerebellar peduncle: contains the afferent posterior spinocerebellar and olivocerebellar tracts. The posterior spinocerebellar tract enters ipsilaterally, the olivocerebellar tract from the contralateral (inferior) olivary nuclei.
