Abstract

Rationale Experimental evidence indicates that the mesolimbic dopamine (DA) pathway innervating the ventral striatum is critically involved in the motivational effects of drug abuse. However, the role of DA transmission of the two main subdivisions of the nucleus accumbens (NAc), the shell and the core, in the motivational properties of nicotine is unknown.Objectives The aim of this study was to investigate the role of DA D1 and D2 receptors of the rat NAc shell and core in the motivational effects of nicotine using a conditioned place preference (CPP) paradigm.Methods The effect of the intracerebral infusion of DA antagonists specific for DA D1 (SCH 39166) and D2 receptors (L-sulpiride) was studied in a single-trial place-conditioning paradigm with fixed assignment of the drug to the unpreferred compartment.Results Nicotine induced significant CPP at the dose of 0.4 and 0.6 mg/kg subcutaneously (s.c.). Intra-NAc shell infusion of SCH 39166 (6.25, 12.5, 25 and 50 ng bilaterally, 10 min before nicotine administration), impaired in a dose-dependent manner the acquisition of CPP by nicotine (0.4 mg/kg s.c.). SCH 39166 failed to affect nicotine CPP when infused into the NAc core. L-sulpiride (25 and 50 ng bilaterally) had no effect on acquisition after intra-Nac shell infusion. SCH 39166 and L-sulpiride were ineffective after infusion in the NAc shell and core 10 min before the test session.Conclusions The results indicate that dopamine D1 but not D2 receptors of the NAc shell are specifically involved in the acquisition of nicotine-induced CPP.

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.
