The nucleus accumbens (NAc or NAcc; also known as the accumbens nucleus, or formerly as the nucleus accumbens septi, Latin for 'nucleus adjacent to the septum') is a region in the basal forebrain rostral to the preoptic area of the hypothalamus. [1]

Sep 21, 2023 · The nucleus accumbens is a region in the brain's basal forebrain that plays a critical role in the reward circuit. It is involved in pleasure, reinforcement learning, and the processing of motivation and reward.

Oct 30, 2023 · The nucleus accumbens functions as an important modulation center between the limbic and the motor systems because of its input from the limbic system and its output to motor nuclei of the basal ganglia. The nucleus accumbens is involved in various cognitive, emotional, and psychomotor functions.

Sep 20, 2017 · What is Nucleus Accumbens? Definition. The nucleus accumbens is a brain part involved in functions such as motivation, reward or positive behavioral reinforcement. The role of nucleus accumbens is to integrate motivation along with the motor action.

The nucleus accumbens is an important component of a major dopaminergic pathway in the brain called the mesolimbic pathway, which is stimulated during rewarding experiences. Watch this 2-Minute Neuroscience video to learn more about the nucleus accumbens.

The term nucleus accumbens was introduced more than a century ago by Ziehen (1897). It is a striatal-like structure by virtue of its prominent afferents from the prefrontal cortex, hippocampus, entorhinal cortex and cortical-like basolateral amygdala (Fallon and Moore, 1978), and from mesencephalic dopamine neurons (Dalhstrom and Fuxe, 1964).

The nucleus accumbens (NAc) is a subcortical brain structure known primarily for its roles in pleasure, reward, and addiction. Despite less focus on the NAc in pain research, it also plays a large role in the mediation of pain and is effective as a source of analgesia.

Oct 22, 2022 · The nucleus accumbens (plural: nuclei accumbentes) (colloquially known as the pleasure center) is a small region in the forebrain involved in the reward pathway and is therefore involved in impulse control disorders.

the region of fusion between the head of the caudate nucleus and the putamen, covered on its inferior aspect by the olfactory tubercle.

Oct 29, 2019 · The nucleus accumbens referred to as NAc or NAcc is a small nucleus present in the basal ganglia of forebrain. It consists of an outer shell, which is a part of the dorsal amygdala, and an inner core, a part of ventral striatum of the basal ganglia.
