The lentiform nucleus or lenticular nucleus describes the putamen and the globus pallidus within the basal ganglia. It is a large, cone-shaped mass of gray matter just lateral to the internal capsule. The name comes from Latin and means lens-shaped, probably referring to the appearance of the nucleus from the side. The putamen is a structure in the middle of the brain, forming the striatum together with the caudate nucleus. ... The globus pallidus is one of the major nuclei of the basal ganglia. ...

The caudate nucleus is a telencephalic nucleus, one of the input nuclei of the basal ganglia; involved with control of voluntary movement in the brain.
The head and body of the caudate nucleus form the part of the floor of the anterior horn of the lateral ventricle.
It is separated from the lenticularnucleus (a structure which includes the putamen) by the internal capsule.
