It is a pair of nuclear masses which form the basal ganglia, along with the subthalamic nucleus and the substantia nigra.It may also refer to both the basal ganglia and internal capsule collectively

Appearance
From lateral to medial, the corpus striatum is composed of the external capsule (white matter), the lentiform nucleus (gray matter), the internal capsule (white matter), and the caudate nucleus (gray matter). The alternating white and gray matter give it a striated appearance.

Anatomy
The corpus striatum has received its name from the striped appearance which a section of its anterior part presents, in consequence of diverging white fibers being mixed with the gray substance which forms its chief mass.

The exact functions of the corpus striatum, embracing the caudate and lenticular nuclei, and of the thalamus are not known. They are most often affected in apoplexies; lesions of the corpus striatum are accompanied by disturbances of motion, and those of the thalamus by disturbances of sensation.
