Definition
The corpus striatum is a grouping of telencephalic nuclei, including the caudate nucleus, the nucleus accumbens, and the lentiform nucleus (putamen and pallidum). It is intersected and surrounded by the internal, external, and extreme capsules, as well as by the claustrum. These structures participate in motor control circuits and in interactions with the cortex and thalamus.
The corpus striatum has the shape of a large ovoid mass of gray matter that occupies the floor of the hemisphere, rostro-lateral to the thalamus, to which it is connected via the internal capsule. It is named for the passage of sheets of white matter between its nuclei.
