Identify the marked structure in the given image ?
Answer C) Lentiform nucleus
The lentiform nucleus, or lenticular nucleus, comprises the putamen and the globus pallidus within the basal ganglia.
With the caudate nucleus, it forms the striatum.
It is a large, lens-shaped mass of gray matter just lateral to the internal capsule.
Increased volume of the lentiform nuclei has been observed in obsessive-compulsive disorder, with decreased volume conversely observed in other anxiety disorders.
