The basal ganglia per se: caudate-putamen ( striatum ) and globus pallidus ( pallidum ) (all basal forebrain / telencephaplic structures: basal ganglia, strictly defined, is caudate, putamen, and gp. All in the basal forebrain/telencephalon: the caudate putamen is a single structure in lower animals. In higher animals, the internal capsule (white matter tract) goes down and splits it into caudate and putamen. When you"re looking at it as one structure will be called striatum: corpus striatum: old name for basal ganglia, neostriatum: may also be applied to caudate-putamen. In justaposition to ventral striatum, which is nucleus accumbens and parts of olfactory tubercule: globus pallidus is also called the pallidum. Related structures: substantia nigra (mesencephalon) and subthalamic nucleus (diencephalon): there are related structures, one in floor of midbrain (substantia nigra) and one in the diaencephalon (subthalamic nucleus, sn: group of dopaminergic cell bodies lie here.
