Goal-directed actions are sensitive to work-related response costs, and dopamine in nucleus accumbens is thought to modulate the exertion of effort in motivated behavior. Dopamine-rich striatal areas such as nucleus accumbens also contain high ...

The purpose of this study was to examine a form of impulsive behavior (impaired inhibition) using cocaine or food reward in addiction-prone and addiction-resistant rats that were bred for high saccharin (HiS) or low saccharin (LoS) intake, ...

Prefrontal cortex AMPA receptor plasticity is crucial for cue-induced relapse to heroin-seeking.
30 Aug 2008 Associative learning processes have an important role in the initiation and persistence of heroin-seeking. Here we show in a rat self-administration model that reexposure to cues previously associated with heroin results in downregulation of AMPA ...

New operant model of nicotine-seeking behaviour in mice.
26 Aug 2008 Nicotine addiction represents a major health problem in the world with dramatic socio-economic consequences. Recent studies using genetically modified mice have provided a better understanding of the neurobiological mechanisms involved in nicotine ...

26 Aug 2008 Nucleus accumbens dopamine is implicated in the primary and conditioned reinforcing properties of abused drugs. In the present study, specific impairments in responding for intravenous cocaine (0.3 mg/inf/0.1 ml/5 s) under a fixed-ratio 1 (FR-1) or ...

26 Aug 2008 It has been shown in previous research [Kaiser, D.H., 2008. The proportion of fixed interval trials to probe trials affects acquisition of the peak procedure fixed interval timing task. Behav. Process., 77 (1), 100-108] that rats acquired peak ...

25 Aug 2008 Increasing evidence suggests that deep brain stimulation (DBS), which is currently being used as a therapy for neurological diseases, may be effective in the treatment of psychiatric disorders as well. Here, we examined the influence of DBS of the ...

Axiomatic methods, dopamine and reward prediction error.
10 Aug 2008 The phasic firing rate of midbrain dopamine neurons has been shown to respond both to the receipt of rewarding stimuli, and the degree to which such stimuli are anticipated by the recipient. This has led to the hypothesis that these neurons encode ...

Time course of the ethanol-like discriminative stimulus effects of abused inhalants in mice.
6 Aug 2008 Abused solvents have effects similar to those of abused depressant drugs. This experiment evaluated the time course of the discriminative stimulus effects of toluene and 1,1,1-trichloroethane (TRI). Mice were trained to discriminate between i.p. ...

6 Aug 2008 Cocaine blocks uptake of the monoamines dopamine, serotonin and norepinephrine, and monoamine uptake inhibitors constitute one class of drugs under consideration as candidate "agonist" medications for the treatment of cocaine abuse and dependence. ...
