abnormal cerebellum dentate nucleus morphology increased cerebellum dentate nucleus size increased corpus dentatum size MPheno.ontology enlarged cerebellum dentate nucleus increased dentate cerebellar nucleus size greater size of the largest and most lateral of the deep cerebellum nuclei; it receives axons of Purkinje cells in the lateral cerebellar hemisphere (neocerebellum) and receives its afferents from the premotor cortex and the supplementary motor cortex through the pontocerebellar system, and its efferents project through the superior cerebellar peduncle and is a major source of its fibers increased lateral cerebellar nucleus size increased cerebellum lateral nucleus size csmith 2013-12-04T22:39:39Z MP:0012487
