Superior cerebellar peduncles are connected together by the superior medullary velum, which can be followed upward as far as the inferior colliculi, under which they disappear. Below, they form the upper lateral boundaries of the fourth ventricle , but as they ascend they converge on the dorsal aspect of the ventricle and thus assist in forming ...
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.

Peduncle: Description: Superior: While there are some afferent fibers from the anterior spinocerebellar tract that are conveyed to the anterior cerebellar lobe via this peduncle, most of the fibers are efferents. Thus, the superior cerebellar peduncle is the major output pathway of the cerebellum.
The superior cerebellar artery arises near the end of the basilar artery. [1] It passes laterally around the brainstem. [1] This is immediately below the oculomotor nerve, [1] which separates it from the posterior cerebral artery. It then winds around the cerebral peduncle, close to the trochlear nerve. It also lies close to the cerebellar ...
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.
The cerebellothalamic tract or the tractus cerebellothalamicus, is part of the superior cerebellar peduncle. It originates in the cerebellar nuclei, crosses completely in the decussation of the superior cerebellar peduncle, bypasses the red nucleus, and terminates in posterior division of ventral lateral nucleus of thalamus. The ventrolateral ...
In the human brain, the expansion of the superior cerebellar peduncle expands the parabrachial nuclei, which form a thin strip of grey matter over most of the peduncle. The parabrachial nuclei are typically divided along the lines suggested by Baxter and Olszewski in humans, into a medial parabrachial nucleus and lateral parabrachial nucleus. [ 1 ]
