Location: The shell is the outer region of the nucleus accumbens, and – unlike the core – is considered to be part of the extended amygdala, located at its rostral pole. Cell types: Neurons in the nucleus accumbens are mostly medium spiny neurons (MSNs) containing mainly D1-type (i.e., DRD1 and DRD5 ) or D2-type (i.e., DRD2 , DRD3 , and ...
Oct 30, 2023 · Location. The nucleus accumbens forms most of the ventral striatum. It is situated in the basal forebrain anterior to the anterior commissure. It lies just inferior to the anterior limb of the internal capsule, and is continuous with the putamen dorsolaterally and the head of the caudate nucleus dorsomedially.
Sep 21, 2023 · Location. The nucleus accumbens (NAcc) is located in the basal forebrain and is a major structure of the ventral striatum, an area of the brain associated with the limbic system, and regulates limbic functions of motivation, affect, and reward.
Abstract. There is increasing interest among functional neurosurgeons in the potential for novel therapies to impact upon diseases beyond movement disorders and pain. 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.
Oct 18, 2019 · The nucleus accumbens (NAc) is a subcortical brain structure located within the ventral striatum. It is often referred to as the pleasure center of the brain for its primary role in positive affect and feelings of reward, but this is an incomplete description.
The nucleus accumbens is found in an area of the brain called the basal forebrain. There is a nucleus accumbens in each cerebral hemisphere; it is situated between the caudate and putamen. The nucleus accumbens is considered part of the basal ganglia and also is the main component of the ventral striatum.
Mar 18, 2020 · The nucleus accumbens (NAc) is a basal forebrain structure located ventromedially to the caudoputamen (CP) and ventrolaterally to the septal nuclei (Groenewegen et al., 1999 ).
