Abstract

There is accumulating evidence that the nucleus accumbens (NAc) plays an important role in the pathophysiology of depression. Given that clinical depression is marked by anhedonia (diminished interest or pleasure), dysfunction of the brain reward pathway has been suggested as contributing to the pathophysiology of depression.Since the NAc is the center of reward and learning, it is hypothesized that anhedonia might be produced by hampering the function of the NAc. Indeed, it has been reported that stress, drug exposure and drug withdrawal, all of which produce a depressive-phenotype, alter various functions within the NAc, leading to inhibited dopaminergic activity in the NAc.In this review, we describe various factors as possible candidates within the NAc for the initiation of depressive symptoms. First, we discuss the roles of several neurotransmitters and neuropeptides in the functioning of the NAc, including dopamine, glutamate, gamma-aminobutyric acid (GABA), acetylcholine, serotonin, dynorphin, enkephaline, brain-derived neurotrophic factor (BDNF), cAMP response element-binding protein (CREB), melanin-concentrating hormone (MCH) and cocaine- and amphetamine-regulated transcript (CART). Second, based on previous studies, we propose hypothetical relationships among these substances and the shell and core subregions of the NAc.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Evidence suggests that dopamine activity is low at times of depression.

    “Evidence suggests that dopamine activity is low at such times (Shirayama and Chaki, 2006).”

    From A motivation model of sex addiction – Relevance to the controversy over the concept (2022) · cites this paper as Shirayama and Chaki, 2006

    The Concluding Remarks report reduced dopaminergic activity in the nucleus accumbens in animal models of depression. This supports the suggested link, but the claim does not retain the paper’s limits to that brain region and primarily rodent evidence. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Restraint stress, the forced swim test, and inescapable shock increase nucleus accumbens dynorphin.

    “Restraint stress, the forced swim test, and inescapable shock increases NAc dynorphin (73) and NAc specific infusion of kappa opioid receptor (i.e., the primary target of dynorphin) antagonists has antidepressant effects (74).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
