The motivation to obtain nicotine-conditioned reinforcers depends on nicotine dose.
15 Sep 2008 
Stimuli associated with nicotine (NIC) can acquire new meaning via Pavlovian conditioning. If a stimulus is associated with the primary reinforcing effects of NIC, the new conditional properties of the stimulus should make it a more valuable ...

Alprazolam and oxazepam block the cue-induced reinstatement of extinguished cocaine seeking in rats.
15 Sep 2008 RATIONALE: We have previously reported that pretreatment with benzodiazepines reduces intravenous cocaine self-administration in rats. OBJECTIVE: This experiment was designed to investigate whether or not benzodiazepines would also inhibit the ...

Cocaine self-administration on a hold-down schedule of reinforcement in rats.
15 Sep 2008 RATIONALE AND OBJECTIVE: Although many contingencies operating in the natural environment include continuous dimensions of responses and reinforcers, previous studies of drug self-administration have almost exclusively used discrete dimensions of ...

Abuse pattern of toluene exposure alters mouse behavior in a waiting-for-reward operant task.
15 Sep 2008 Inhaling solvents for recreational purposes continues to be a world-wide public health concern. Toluene, a volatile solvent in many abused products, adversely affects the central nervous system. However, the long-term neurobehavioral effects of ...

14 Sep 2008 RATIONALE: The use of animal models to study existing medications for smoking cessation can elucidate the mechanism(s) of action of cessation agents and further validate the models for medication development. OBJECTIVE: The objective of the study ...

Facilitation of extinction of operant behaviour in mice by D-cycloserine.
9 Sep 2008 RATIONALE AND OBJECTIVE: The N-methyl-D-aspartate receptor agonist D-cycloserine (DCS) facilitates extinction following Pavlovian fear conditioning or conditioned place preference in rats, but its effects on extinction following operant conditioning ...

Dynamic behavioural changes in the Spontaneously Hyperactive Rat: 2. Control by novelty.
4 Sep 2008 An important aspect of attention deficit hyperactivity disorder (ADHD) is its temporary amelioration by novelty and by stimulant medication. Extant learning-based accounts of ADHD are unable to account for the temporary amelioration effect. One ...

4 Sep 2008 Several existing theoretical models of Attention Deficit Hyperactivity Disorder (ADHD) predict that a high or low learning rate contributes to some cases of ADHD; and that this is controlled by the dopamine signal. The Spontaneously Hypertensive ...

4 Sep 2008 Variable intervals are widely believed to produce steady rates of responding. However, based on the calming effect of unpredictability in attention deficit hyperactivity disorder (ADHD) we hypothesised that an animal model of this disorder, the ...

4 Sep 2008 Several lines of evidence suggest that exploring the neurochemical basis of reward in invertebrate species may provide clues for the fundamental behavioral and neurobiology underpinnings of drug addiction. How the presence of drug-sensitive reward ...
