The inferior cerebellar peduncle is the smallest of the three cerebellar peduncles. The upper part of the posterior district of the medulla oblongata is occupied by the inferior cerebellar 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 cerebellar peduncles are three paired bundles of fibres that connect the cerebellum to the brain stem. [1] Superior cerebellar peduncle is a paired structure of white matter that connects the cerebellum to the mid-brain. Middle cerebellar peduncles connect the cerebellum to the pons and are composed entirely of centripetal fibers.
This suggests that the dorsal spinocerebellar tract carries sensory information to the spinocerebellum through the inferior cerebellar peduncle during movement (since the inferior peduncle is known to contain fibres from the dorsal tract), and that the ventral spinocerebellar tract carries internally generated motor information about the ...

The vestibulocerebellar tract fibers are second-order fibers from the vestibular nuclei, and first-order fibers from the vestibular ganglion/nerve. [1] They pass through the juxtarestiform body of the inferior cerebellar peduncle to reach the cerebellum, [1] They terminate in the vestibulocerebellum, and part of the vermis as well as the dentate nucleus, and fastigial nucleus in each ...
The juxtarestiform body is the smaller, medial subdivision of each inferior cerebellar peduncle (the other, lateral one being the restiform body). [1]: 290 The juxtarestiform body contains mostly cerebellar afferents, but also some cerebellar efferents. [1]: 290
They receive afferents from the corticospinal tract. [citation needed] They in turn project efferents into the cerebellum through the inferior cerebellar peduncle as: [1] the anterior internal arcuate fibers which pass along the midline before decussating near the rhomboid fossa (floor of fourth ventricle) then passing laterally as the ...
The cerebral peduncles (In Latin, ped-means 'foot'.) are the two stalks that attach the cerebrum to the brainstem. [1] They are structures at the front of the midbrain which arise from the ventral pons and contain the large ascending (sensory) and descending (motor) tracts that run to and from the cerebrum from the pons.
