NCIt definition : A sub-cortical, paired nuclei that, though migrated to the telencephalon, is a critical
part of the basal ganglia, along with the caudate nucleus and the putamen, the latter
of which it joins to form the lentiform nucleus. Each nucleus is subdivided into internal
and external parts, called globus pallidus interna and globus pallidus externa, which
are separated by an internal medullary lamina.;
Alternative definition : CDISC: Paired nuclei at the base of the forebrain that, along with the putamen, form
the lentiform nucleus of the basal ganglia.;
