Detailed explanation-1: -The superior cerebellar peduncles, also known as the brachium conjunctivum, are paired white matter fiber tracts that connect the cerebellum with the midbrain. The superior cerebellar peduncle contains vital afferent and efferent fibers including cerebellothalamic, cerebellorubral and ventrospinocerebellar tracts.
Detailed explanation-2: -The cerebellum is connected to the brainstem by three pairs of peduncles (superior, middle, and inferior), which are the pathways by which cerebellar afferents and efferents enter and exit [23, 24]. Cerebellar afferents can be grouped into two major types: mossy fibers and climbing fibers.
Detailed explanation-3: -The dentate projects fibers out of the cerebellum through the superior cerebellar peduncle, which cross midline within the midbrain, inferior to the red nucleus, to synapse in the ventrolateral nucleus of the thalamus and also in the red nucleus.
