one of two cerebellar nuclei interposed between the dentate and the fastigial nuclei; a small wedge-shaped nucleus in the central white substance of the cerebellum just internal to the hilus of the dentate nucleus; receives axons of Purkinje cells of the intermediate area of the cerebellar cortex; axons of these cells exit the cerebellum via the superior cerebellar peduncle. SYN: nucleus emboliformis*, embolus (2).
