Amphetamine injections into the nucleus accumbens affect neither acquisition/expression of conditioned fear nor baseline startle response

The results suggest that dopamine within the NAC is not involved in modulation of fear-potentiated startle and baseline startle, and that amphetamine injections into the nucleus accumbens clearly enhanced spontaneous motor activity.

The Nucleus Accumbens Core is Necessary to Scale Fear to Degree of Threat

The results reveal that the NAcc is essential to scale fear to degree of threat, and is a plausible source of dysfunction in stress and anxiety disorders.

Prefrontal cortical and nucleus accumbens contributions to discriminative conditioned suppression of reward-seeking

Fear can potently inhibit ongoing behavior, including reward-seeking, yet the neural circuits that underlie such suppression remain to be clarified. Prior studies have demonstrated that distinct

Transient Inactivation of Shell Part of Nucleus Accumbens Inhibits and Exacerbates Stress-Induced Metabolic Alterations in Wistar Rats

The data indicated that right side of shell part of nucleus accumbens (NAc) transient inactivation leads to reduction in metabolic signs of stress but left side ofshell part of the NAc inactivation even exacerbates stress signs.



Selective excitotoxic lesions of the nucleus accumbens core and shell differentially affect aversive Pavlovian conditioning to discrete and contextual cues

The nucleus accumbens is implicated in aspects of aversive Pavlovian conditioning; the significance of this finding for theories of cortico-striatal function is discussed.

An infusion of bupivacaine into the nucleus accumbens disrupts the acquisition but not the expression of contextual fear conditioning.

A critical role for the Acb in the acquisition but not the expression of contextual fear conditioning is demonstrated and is consistent with the view that this structure is involved in the processes by which rats represent a context.

Shock sensitization of startle in rats: the role of contextual conditioning.

Results show that shock sensitization of startle is mediated by contextual conditioning, and the implications of this finding for using the shock sensitized procedure as a model preparation for examining the neural and pharmacological bases of unconditioned fear are discussed.

A differential involvement of the shell and core subterritories of the nucleus accumbens of rats in memory processes.

The role of the core and the shell subterritories of the nucleus accumbens in conditioned freezing and spatial learning was investigated by means of selective N-methyl-D-aspartate lesions.

Time-Dependent Deficits of Rat′s Memory Consolidation Induced by Tetrodotoxin Injections into the Caudate-Putamen, Nucleus Accumbens, and Globus Pallidus

Tetrodotoxin functional ablation was employed to assess the respective roles of the caudate-putamen as a whole and of its anterior, median, and posterior regions, of the nucleus accumbens, and of the globus pallidus during early passive avoidance response consolidation of the rat.

Footshocks increased startle in rats not previously given startle-eliciting stimuli, indicating sensitization rather than dishabituation, and may represent the unconditioned effect of shock that can become associated with a neutral stimulus to support classical fear conditioning.
