Amphetamine pretreatment accelerates the subsequent escalation of cocaine self-administration behavior

Abstract

It has been proposed that some neuroadaptations that underlie behavioral sensitization may play a role in the development and persistence of addiction. However, whether or not sensitization facilitates the development of symptoms specific to addiction, such as the escalation of drug intake, is not known. We examined, therefore, the effect of pretreatment with a sensitizing regimen of amphetamine on the escalation of subsequent drug intake in rats given the opportunity to self-administer cocaine. Amphetamine pretreatment produced psychomotor sensitization and also accelerated the subsequent escalation of cocaine intake. This suggests that the neural circuits that are altered as a consequence of repeated amphetamine treatment, and the induction of sensitization, may overlap with those responsible for the development of some addiction-like behaviors.

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.
