A cerebellar peduncle is a nerve tract that permits communication between the cerebellum and the other parts of the central nervous system. Three pairs of cerebellar peduncles conduct this communication. The inferior peduncles bring sensory information about the actual position of body parts such as limbs and joints.

What do peduncles do?

As a whole, the cerebral peduncles assist in refining motor movements, learning of new motor skills, and converting proprioceptive information into balance and posture maintenance. Important fiber tracts that run through the cerebral peduncles are the corticospinal, corticopontine, and corticobulbar tracts.

What is the function of middle cerebellar peduncles?

The middle cerebellar peduncles (brachium pontis) are paired structures (left and right) that connect the cerebellum to the pons and are composed entirely of centripetal fibers, i.e. incoming fibers.
