| neocerebellum | Phylogenetic term referring to the larger lateral portion of the cerebellar hemisphere receiving its dominant input from the pontine nuclei which, in turn, are dominated by afferent nerves originating from all parts of the cerebral cortex; phylogenetically, of more recent origin than the archicerebellum and paleocerebellum, q.v., the neocerebellum reaches its largest development in humans and other primates. Synonym: corticocerebellum. (05 Mar 2000) |

| neocerebellum |
[TA] the phylogenetically newest part of the cerebellum, considered to correspond to its lateral parts, including the cerebellar hemispheres and the middle portion of the vermis. Because the hemispheres are the primary site of termination of the projections from the pons, the corticopontocerebellar fibers, the term is sometimes equated with pontocerebellum. Cf. archicerebellum and paleocerebellum.
