Nucleus Accumbens Core. The nucleus accumbens NAc is clearly implicated in reward processing and drug addiction as well as in numerous neurological and psychiatric disorders. The nucleus accumbens receives glutaminergic dopaminergic and histaminergic input fibers from different areas of the brain. Its former name nucleus accumbens septi a nucleus leaning against the septum refers to a medial hook-shaped expansion of this anteroventral region of the striatum which curves under the floor of the frontal horn of the lateral ventricle and ascends for. The region of fusion between the head of the caudate nucleus and the putamen covered on its inferior aspect by the olfactory tubercle.

It is also called nucleus accumbens core or NAcc core. In general this result has held up in subsequent studies using different variants of the delayed discounting procedure. The nucleus accumbens core is with the nucleus accumbens shell a subregion of the nucleus accumbens. NAshell nucleus accumbens shell. The region of fusion between the head of the caudate nucleus and the putamen covered on its inferior aspect by the olfactory tubercle. The nucleus accumbens core is an important interface between the limbic and motor systems and plays a particularly important role in motivated behavior.
Nucleus accumbens NAc neurons encode features of stimulus learning and action selection associated with rewards.
The nucleus accumbens NAc is clearly implicated in reward processing and drug addiction as well as in numerous neurological and psychiatric disorders. It is present in the inner region of the nucleus accumbens. The nucleus accumbens receives glutaminergic dopaminergic and histaminergic input fibers from different areas of the brain. In two experiments we induced nucleus accumbens core NAcc dysfunction in rats receiving fear discrimination consisting of cues for danger uncertainty and safety. The medium spiny neurons in the nucleus accumbens receive input from both the dopaminergic neurons of the VTA and the glutamatergic neurons of the hippocampus amygdala and medial prefrontal cortex. Functional differentiation in valence processing has previously been found along the rostrocaudal axis of the shell region of the NAc in assessments of unconditioned motivation.

Nevertheless the circuit mechanisms underlying the diverse functions of the NAc remain poorly understood. Consistent with our previous findings 34 35 FGF2 mRNA levels in the core of the nucleus accumbens were higher in bHRs relative to bLRs under basal conditions t 9 577 P 00003 and these differences were also apparent following prolonged cocaine self-administration t 9 242 P 0038 Fig. 48 initially reported that selective bilateral excitotoxic lesions of the nucleus accumbens core region but not the anterior cingulate or the medial PFC resulted in more impulsive choice using a temporal discounting task. Nucleus accumbens NAc neurons encode features of stimulus learning and action selection associated with rewards. The nucleus accumbens NAc is thought to be a site of integration of positively and negatively valenced information and action selection.
