Superior cerebellar peduncle

The superior cerebellar peduncle is one of three large fiber bundles that connect the cerebellum to the dorsal aspect of the brainstem. It receives afferents from the premotor cortex and supplementary motor cortex via the pontocerebellar system and its efferents project through the red nucleus to the ventrolateral thalamus, crossing over at the pontomesencephalic junction.From: Neuromuscular Fundamentals [2020], Computational RSM modelling of dentate nucleus neuron 2D image surface [2018]

The cerebellum is connected to the dorsal aspect of the brainstem by three large fiber bundles on either side, referred to as the cerebellar peduncles, and identified as: the inferior cerebellar peduncle, or restiform body, the middle cerebellar peduncle, or brachium pontis, and the superior cerebellar peduncle, or brachium conjunctivum.

The dentate nucleus occupies a central position in the cerebellar circuitry, serving as a relay centre for fibres coming from the cerebellar cortex, namely from the axons of Purkinje cells (Chan-Palay 1977). It represents the largest and phylogenetically most recent of the cerebellar white matter nuclei and plays an important role as a major relay centre between the cortex and the other parts of the brain. It receives its afferents from the premotor cortex and supplementary motor cortex (via the pontocerebellar system) and its efferents project via the superior cerebellar peduncle through the red nucleus to the ventrolateral thalamus (crossing over at the pontomesencephalic junction). It is responsible for the planning, initiation and control of volitional movements (Mathiak et al. 2002).
