the large cone-shaped mass of gray matter forming the central core of the cerebral hemisphere. The convex base of the cone, oriented laterally and rostrally, is formed by the putamen, which together with the caudate nucleus composes the neostriatum; the apical part, oriented medially and caudally, consists of the two segments of the globus pallidus. The nucleus is anterolateral (ventrolateral) to the thalamus and caudate nucleus, from which it is separated by the internal capsule, and together with the caudate nucleus comprises the striate body.
