lentiform nucleus

The large, cone-shaped mass of gray matter that forms the central core of the cerebral hemisphere, whose outermost convex base is formed by the putamen and whose innermost apical part consists of the globus pallidus. Also called lenticular nucleus.

[From its somewhat biconvex appearance when viewed from certain angles.]
