This paper reviews some of our most recent findings on the organization of the afferent and efferent connections of the globus pallidus (GP) in the squirrel monkey (Saimiri sciureus). Its main purpose is to demonstrate that even though all pallidal neurons express the same phenotype in terms of both morphology and chemospecificity, the analysis of afferent and efferent connections of GP reveals that this major component of the basal ganglia is in fact a dual entity in primates.
