What is "cerebellar peduncle"

Cerebellar peduncle is the part that connects cerebellum to the brain stem. There are 6 cerebellar peduncles in total, 3 on the left and 3 on the right. It may refer to:

• Superior cerebellar peduncle - primary output of the cerebellum with mostly fibers carrying information to the midbrain
• Middle cerebellar peduncle - carry input fibers from the contralateral cerebral cortex
• Inferior cerebellar peduncle - receives ipsilateral proprioceptive information from the spinal cord.
