Superior cerebellar peduncle
|Brain: Superior cerebellar peduncle|
|Sagittal section of the cerebellum, near the junction of the vermis with the hemisphere. (Superior peduncle labeled at upper right.)|
|Dissection showing the projection fibers of the cerebellum. (Superior peduncle labeled at center top.)|
|Latin||pedunculus cerebellaris superior|

The superior cerebellar peduncles (brachia conjunctiva), 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.
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 spinal cord to the cerebellum (Ventral Spinocerebellar Tract) pass through the superior cerebellar peduncle.
