I wanted this part to show how other research papers have not been able to exactly target or localize the globus pallidus externa and its role in all the cognitive, neuropsychiatric manifestations. Usually the papers group basal ganglia as a whole but we want to pin point the role of the GPE that may never have been discussed or explored before, aside from the motor symptoms. Also explain how its a poorly explored area and how pin pointing it may help clinically
