Impulsivity predicts the escalation of cocaine self-administration in rats.

29 May 2009 Impulsivity, as measured by the delay-discounting task, predicts the acquisition of cocaine self-administration and reinstatement of cocaine seeking in rats. The purpose of this study was to extend these results to the escalation phase of drug ...

Delta-9-tetrahydrocannabinol enhances food reinforcement in a mouse operant conflict test.

17 May 2009 RATIONALE: Cannabinoid compounds are known to regulate feeding behavior by modulating the hedonic and/or the incentive properties of food. OBJECTIVES: The aim of this work was to determine the involvement of the cannabinoid system in food ...

Rats self-administer intravenous nicotine delivered in a novel smoking-relevant procedure: effects of dopamine antagonists.

13 May 2009 Attempts to explain tobacco addiction have relied heavily on the assumption that each cigarette puff delivers a bolus of nicotine to the brain within seconds. However, nicotine transits from lungs to brain much more gradually than once thought. ...

Contingency management and motivational enhancement: a randomized clinical trial for college student smokers.

12 May 2009 INTRODUCTION: The efficacy of contingency-management (CM) and motivational enhancement therapy (MET) for college student smoking cessation was examined. METHODS: Nontreatment-seeking daily smokers (N = 110) were randomly assigned to 3 weeks of CM ...

Control of within-binge cocaine-seeking by dopamine and glutamate in the core of nucleus accumbens.

11 May 2009 RATIONALE: Dopamine and glutamate are thought to interact in the ventral striatum and to play important roles there in the cocaine-seeking of cocaine-experienced animals. OBJECTIVES: We sought to determine the relative roles of the two transmitters ...

Behavioral and neurochemical effects of cocaine and diphenhydramine combinations in rhesus monkeys.

7 May 2009 RATIONALE: Diphenhydramine (DPH) is an over-the-counter medication used in the treatment of allergic symptoms. While DPH abuse is infrequent, recent preclinical evidence suggests that DPH and cocaine combinations may have enhanced reinforcing ...

Diverse and often opposite behavioural effects of NMDA receptor antagonists in rats: implications for "NMDA antagonist modelling" of schizophrenia.

5 May 2009 RATIONALE: Little attention has been paid to the relative equivalence of behavioural effects of NMDA receptor antagonists in rodents, with different compounds often used interchangeably to "model" aspects of schizophrenia in preclinical studies. ...

Role of dopamine transporters in the behavioral effects of 3,4-methylenedioxymethamphetamine (MDMA) in nonhuman primates.

5 May 2009 RATIONALE: The interoceptive and reinforcing effects of 3,4-methylenedioxymethamphetamine (MDMA) are similar to those of psychostimulants, but the role of dopamine in the behavioral effects of MDMA is not well documented, especially in primates. ...

Does the learning deficit observed under an incremental repeated acquisition schedule of reinforcement in Ts65Dn mice, a model for Down syndrome, change as they age?

May 2009 The Ts65Dn mouse is partly trisomic at chromosome 16 and is considered to be a valid mouse model of human Down syndrome. Prior research using an incremental repeated acquisition (IRA) schedule of reinforcement has revealed that there is a ...

Changes in the relative reinforcing effects of cigarette smoking as a function of initial abstinence.

22 Apr 2009 RATIONALE: Experimental research is needed in investigating how early smoking abstinence affects relapse risk. OBJECTIVE: The present study assessed the feasibility of promoting smoking abstinence using once- rather than thrice-daily abstinence ...
