Inferior cerebellar peduncle
The upper part of the posterior district of the medulla oblongata is occupied by the inferior peduncle, a thick rope-like strand situated between the lower part of the fourth ventricle and the roots of the glossopharyngeal and vagus nerves.
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.
This tract passes through the inferior cerebellar peduncle and synapses within the paleocerebellum.
Vestibular information projects onto the archicerebellum.
