... with AUD, in vivo dopamine D2 and D3 receptor availability appears to be reduced, which may be a predisposing factor or the result of a neuroadaptive process influencing drug-induced DA release. DA transporter availability is reduced in AUD, whereas findings with respect to DA synthesis capacity...

... to assessing the behavioural effects and dopamine neurotransmitter changes produced. Male Sprague-Dawley rats received 4 subcutaneous doses of methamphetamine (0.5, 1, 2, and 4 mg/kg, or saline as a control) 2 h apart. Methamphetamine had a dose-dependent stimulatory effect on locomotor activity over the 8 h...

Neurochemical analysis using high-performance liquid chromatography revealed few lasting changes in serotonin, dopamine or their metabolites in the striatum or prefrontal cortex of MDMA- or GHB-pre-exposed rats. These results indicate that GHB modulates the locomotor and hyperthermic response...
