The superior cerebellar peduncles (brachium conjunctivum), two in number, emerge from the upper and medial part of the white substance of the hemispheres and are placed under cover of the upper part of the cerebellum.

They are joined to each other across the middle line by the anterior medullary velum, and can be followed upward as far as the inferior colliculi, under which they disappear.

Below, they form the upper lateral boundaries of the fourth ventricle, but as they ascend they converge on the dorsal aspect of the ventricle and thus assist in roofing it in.

All fibers (except vestibular fibers to the vestibular nuclei through the inferior cerebellar peduncle) carrying information from the cerebellum to the midbrain and pons pass through the superior cerebellar peduncle.
