The nucleus accumbens (NAc) is a key node of the brain’s circuitry that is responsible for translating motivation into action. It has been implicated in playing critical roles in virtually all forms of adaptive and pathological motivated behaviors. It is subject to modulation by a broad array of inputs that influence NAc activity in complex ...
The nucleus accumbens may play an important role in behaviors related to addiction and chronic pain. Recent observations in addicted humans likewise reinforce the concept that the nucleus accumbens is a gratification site. These patients show marked binding of substances to cells in nucleus accumbens.
The nucleus accumbens (NAcc) is a small structure located in the ventral striatum. From a clinical neuroimaging perspective, the NAcc is difficult to image given its size and proximity to cerebral sinuses and pulsating arterioles. Specifically, the NAcc is approximately 1–2 cm 3 in humans relative to a whole-brain volume of 1100 + cm 3 ( Neto ...
Mar 19, 2015 · The nucleus accumbens (NAc) is a major component of the ventral striatum and has long been thought to be a key structure involved in mediating motivational and emotional processes, the limbic-motor interface, and the effects of certain psychoactive drugs.
Jul 22, 2022 · Objective: The nucleus accumbens (NAcc) of the ventral striatum is critically involved in goal- and reward-based behavior. Structural and functional abnormalities of the NAcc or its associated neural systems are involved in neurological and psychiatric disorders.
Jan 3, 2015 · Nearly 40 years of research on the function of the nucleus accumbens (NAc) has provided a wealth of information on its contributions to behavior but has also yielded controversies and misconceptions regarding these functions. A primary tenet of this review is that, rather than serving as a "reward" …
