Basal extracellular dopamine levels in the nucleus accumbens are decreased during cocaine withdrawal after unlimited-access self-administration

Abstract

The effects of withdrawal from cocaine on extracellular dopamine (DA) levels in the nucleus accumbens (NAC) were examined by intracranial microdialysis in awake rats after periods (9.5-21.75 h) of unlimited-access, intravenous cocaine self-administration. Cocaine withdrawal was associated with significant reductions in basal DA overflow that persisted up to 12 h. Maximal inhibition of DA release (mean +/- S.E.M. 66.15 +/- 3.30 percent of basal levels) was observed between 4-6 h after cessation of cocaine intake and was positively correlated (r = 0.88) with the duration of the preceding self-administration episode. The results suggest that suppression of basal DA release in the NAC is an adaptive consequence of sustained cocaine exposure and may in part underlie the post-cocaine anhedonia observed in behavioral models of cocaine withdrawal.

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.
