Nucleus Accumbens Core

The nucleus accumbens core is, with the nucleus accumbens shell, a subregion of the nucleus accumbens. The nucleus accumbens core is an important interface between the limbic and motor systems, and plays a particularly important role in motivated behavior.

Connectivity
The nucleus accumbens core shares many of its afferent and efferent connections with the nucleus accumbens shell.

Structure
The nucleus accumbens core is primarily comprised of GABAergic medium spiny neurons, which for the most part project to other regions of the basal ganglia.

Role in behavior
The role of the nucleus accumbens core has been investigated in several behaviors.
