The upper part of the posterior district of the medulla oblongata is occupied by the inferior cerebellar peduncle (restiform body), a thick rope-like strand situated between the lower part of the fourth ventricle and the roots of the glossopharyngeal and vagus nerves.
Each cerebellar inferior peduncle connects the spinal cord and medulla oblongata with the cerebellum, and comprises the juxtarestiform body and restiform body.
Important fibers running through the inferior cerebellar peduncle include the spinocerebellar tract and axons from the inferior olivary nucleus, among others.

Function[edit]
The inferior cerebellar peduncle carries many types of input and output fibers that are mainly concerned with integrating proprioceptive sensory input with motor vestibular functions such as balance and posture maintenance.
Proprioceptive information from the body is carried to the cerebellum via the posterior spinocerebellar tract.
This tract passes through the inferior cerebellar peduncle and synapses within the spinocerebellum (also known as the paleocerebellum).
Vestibular information projects onto the vestibulocerebellum (also known as the archicerebellum).
This peduncle also carries information directly from the Purkinje cells to the vestibular nuclei in the dorsal brainstem located at the junction between the pons and medulla oblongata.
