The corticopontine fibers descend from cortex uncrossed to end upon the pontine nuclei. Cells within the pontine grey then project via the MIDDLE CEREBELLAR PEDUNCLE (or brachium pontis) to the CONTRALATERAL cerebellum via pontocerebellar fibers. This cortico-ponto-cerebellar pathway is quantitatively the most important route by which the cerebral cortex can influence the cerebellar cortex. The corticopontine projection carries information that the contralateral cerebellum (via a synapse in the pontine grey) uses to participate in the preparation to move and in the initiation and execution of movements.
