Medical Definition of Pedunculus cerebellaris superior

1. A large bundle of nerve fibres that originate from the dentate and interpositus nuclei and emerges from the cerebellum in the rostral direction, along the lateral wall of the fourth ventricle. The bundle submerges from the dorsal surface of the brainstem into the mesencephalic tegmentum, where all of its fibres cross in the massive decussation of the superior cerebellar peduncles. Part of the bundle terminates in the contralateral red nucleus; the bulk of the fibres continue rostrally to parts of the ventral intermediate nucleus of thalamus, ventral posterolateral nucleus of thalamus, and central lateral nucleus of thalamus. Synonym: pedunculus cerebellaris superior, brachium conjunctivum cerebelli. (05 Mar 2000)
