Definition for Globus pallidus
From Biology Forums Dictionary
The globus pallidus also known as paleostriatum, is a sub-cortical structure of the brain.
Topographically, it is part of the telencephalon, but retains close functional ties with the subthalamus - both of which are part of the extrapyramidal motor system. The globus pallidus is a major component of the basal ganglia core along with the striatum and its direct target, the substantia nigra. The latter are made up of similar neuronal elements, have similar afferents from the dorsal striatum and have a similar synaptology; neither receive cortical afferents.
