The Inferior Cerebellar Peduncle (ICP), also known as the restiform body, is one of three paired structures (the cerebellar peduncles) that connect the cerebellum to the brainstem. The ICP primarily carries afferent fibers to the cerebellum from the spinal cord and the medulla oblongata.

Structure

The Inferior Cerebellar Peduncle is located in the posterior part of the medulla oblongata, lateral to the fourth ventricle. It is formed by afferent fibers, including the dorsal spinocerebellar tract, the cuneocerebellar tract, and various other tracts from the medulla.

Function

The ICP carries sensory information from the body to the cerebellum. This includes proprioceptive information, which helps the body understand its position in space, and tactile information, which helps the body sense touch.

Clinical Significance

Damage to the Inferior Cerebellar Peduncle can result in a variety of neurological disorders, including ataxia, nystagmus, and dysarthria. These conditions can affect balance, eye movements, and speech, respectively.
