Definition

Striatum is a subcortical part of the telencephalon that represents the principal receptive component of the basal ganglia system.

Current Knowledge

The striatum is spatially subdivided into dorsal and ventral striatum. The dorsal striatum is topographically separated by the internal capsule to the caudate and putamen, while the ventral striatum contains the nucleus accumbens and the striatal part of the olfactory tubercle. The selective distribution of the axonal terminals that originate from cortical sources differentiates three distinct striatal territories: sensorimotor, associative, and limbic. More information on the anatomical divisions of the striatum can be found in Voorn et al. (2004). Immunochemically, particularly based on acetylcholine esterase staining, the adult striatum is made up of two compartments: “striosomes” (weak staining) and matrix (strong staining).

The striatum is homogeneous in terms of neuronal components. It is built of...
