Globus pallidus

Last revised by Ali Alsmair on 9 Feb 2022

The globi pallidi (singular: globus pallidus) are paired structures and one of the nuclei that make up the basal ganglia. Each globus pallidus is a subcortical structure at the base of the forebrain and in anatomical relation to the caudate nucleus and putamen. It forms the lentiform nucleus with the putamen.

Each globus pallidus is itself subdivided into two parts, the globus pallidus internus and globus pallidus externus, separated by an internal medullary lamina.

Developmentally, the globus pallidus is a part of the diencephalon that has migrated to the telencephalon, but it is still considered to be part of the basal ganglia.
