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. The nucleus accumbens and the olfactory tubercle collectively form the ventral striatum.

Learn about the nucleus accumbens, a brain structure involved in reward-related behaviors and drug addiction. Find out how it receives and integrates inputs from various regions and how it modulates reinforcement learning and motivation.
A target of increasing interest is the nucleus accumbens (NAc), which has long been studied as a key brain region mediating a variety of behaviors, including reward and satisfaction. As such, focal modulation of the biology of the NAc with deep brain stimulation or novel biological therapies such as gene therapy or cell transplantation could ...

Sep 20, 2017 · The nucleus accumbens is a brain part involved in pleasure, reward, learning, memory, and addiction. It connects with the limbic system, the hippocampus, and the basal ganglia. It releases dopamine in response to positive or negative stimuli. It is also involved in the placebo effect, love, and fear.
The nucleus accumbens (NAc), a key node of mesolimbic dopamine (DA) circuitry (Volkow et al. 2017), has long been conceptualized as a critical functional connection between limbic system structures, such as the amygdala and hippocampus, and motor systems including the basal ganglia (Mogenson et al. 1980).
