Food restriction has been shown to increase self‐administration of psychostimulants,
including cocaine and amphetamine (AMPH). Consistent with this, food‐restricted rats are …

Food-deprivation increases the reinforcing efficacy of cocaine and other drugs within self-
administration experiments. In this study, the effects of food-deprivation on cocaine-induced …

Cocaine conditioned place preference (CPP) is more persistent in food-restricted than ad
libitum fed rats. This study assessed whether food restriction acts during conditioning and/or …

Rationale Chronic food restriction (FR) increases rewarding effects of abused drugs and
persistence of a cocaine-conditioned place preference (CPP). When there is a single daily …

Previously, a learning-free measure was used to demonstrate that chronic food restriction
(FR) increases the reward magnitude of a wide range of abused drugs. Moreover, a variety …

In this study, we measured conditioned place preference (CPP) responses to cocaine
following subchronic administration of the recreationally abused drug (±)‐3, 4 …

Withdrawal following chronic exposure to opiates or other drugs of abuse, administered as
frequent doses, or a chronic infusion can cause reductions in mesolimbic dopamine (DA) …

This experiment was undertaken to investigate the role of nucleus accumbens dopamine
(DA) in instrumental and consummatory responses for food. In vivo microdialysis methods …

Rationale It has been demonstrated that major differences between mice of the C57BL/6J
and DBA/2J inbred strains for amphetamine-induced place conditioning (preference and …

Rationale: In previous comparisons with C57BL/6J mice, DBA/2J mice have been
characterized as” hyporesponsive” to cocaine's rewarding effect in the conditioned place …
