Stress- and pharmacologically-induced behavioral sensitization increases vulnerability to acquisition of amphetamine self-administration

Abstract

Individual vulnerability to drug addiction may be an important factor in the prognosis of this pathological behavior in man. However, experimental investigations have largely neglected the psychobiological substrate of predisposition to addiction. In this study, we show using a self-administration (SA) acquisition paradigm that previous repeated exposure to a stressful experience (tail-pinch) or to amphetamine, increase the locomotor response to this drug (behavioral sensitization) and enhance vulnerability to acquire amphetamine SA. These results show that vulnerability to develop amphetamine SA may be influenced by stressful experiences, and that previous contact with the drug may enhance a predisposition to amphetamine-taking behavior. As tail-pinch and amphetamine sensitization affect both the dopamine (DA) neural system and the propensity to self-administer amphetamine (behavior also modulated by DA activity), stress may influence SA via an action on the DA system.

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.
