pontocerebellum

Those areas of the cerebellar cortex that receive input from cells of the basilar pontine nuclei; includes all cortical regions; projections to the hemisphere greater than to the vermis; pontocerebellar fibers send collaterals to the cerebellar nuclei enroute to the overlying cortex.

pon·to·cer·e·bel·lum (pon″to-ser″ə-belґum) [ponto- + cerebellum] [TA] the portion of the cerebellum whose afferent inflow is predominantly supplied by corticopontocerebellar fibers, roughly corresponding to the cerebellar hemispheres; therefore, the term is sometimes equated with neocerebellum, which is the anatomical division of the cerebellum comprising the lateral parts, including most of the hemispheres and the middle portion of the vermis. Cf. spinocerebellum and vestibulocerebellum.
