Insula
QuestionChoice
Correct. The lentiform nucleus is a region of grey matter within the basal ganglia, comprising the globus pallidus (medially) and the putamen (laterally), each with distinct functional properties. The medial medullary lamina separates the internal and external globus pallidus, and the lateral medullary lamina separates the external globus pallidus and the putamen. The lentiform nucleus carries out complex functions related to movement, cognition and emotion.
