The corpus striatum (striated body) is a term used in a few different ways:
- It is sometimes used as another term for the basal ganglia.
- It may also refer to both the basal ganglia and internal capsule collectively.
- According to the 1917 version of Gray's Anatomy, it is the combination of the lentiform nucleus (also known as the lenticular nucleus) and the caudate nucleus
- According to BrainInfo (see link in infobox) it is a part of the basal ganglia comprising the globus pallidus and striatum.

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.
A part of the corpus striatum is imbedded in the white substance of the hemisphere, and is therefore external to the ventricle; it is termed the extraventricular portion, or the lenticular nucleus.
The remainder, however, projects into the ventricle, and is named the intraventricular portion, or the caudate nucleus.
