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 ...

Different neural systems mediate morphine reward and its spontaneous withdrawal aversion.
7 May 2009 The opponent-process theory posits that the aversive state of acute opiate withdrawal is a consequence of, and depends on, the previous rewarding state evoked by acute morphine reward. Although the brainstem tegmental pedunculopontine nucleus (TPP) ...

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. ...

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. ...

4 May 2009 RATIONALE: In humans, the retrieval of memories associated with an alcohol-related experience frequently evokes alcohol-seeking behaviour. The reconsolidation hypothesis states that a consolidated memory could again become labile and susceptible to ...

Pavlovian conditioning of multiple opioid-like responses in mice.
3 May 2009 Conditional responses in rodents such as locomotion have been reported for drugs of abuse and similar to the placebo response in humans, may be associated with the expectation of reward. We examined several conditional opioid-like responses and the ...

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 ...

May 2009 High doses of apomorphine induce sensitization to locomotor stimulant effects whereas low doses induce locomotor inhibition. We examined whether repeated low dose apomorphine induced sensitization and conditioning to the locomotor inhibitory effect. ...

29 Apr 2009 RATIONALE: Cannabis preparations are the most widely consumed illicit drugs, and their use typically begins in adolescence. The prevalence of cannabis abuse is higher in patients with attention deficit/hyperactivity disorder (ADHD) than in the ...

29 Apr 2009 When differential outcomes follow correct responses to each of two comparison stimuli in matching to sample, relative to the appropriate control condition, higher matching accuracy is typically found, especially when there is a delay between the ...
