Repeated administration of amphetamine-like psychostimulants produce a progressive and long-lasting hypersensitivity to their behavioural effects known as behavioural sensitization. Previous studies have shown that administration of the purinergic P2 receptor agonist 2-methylthio ATP into the nucleus accumbens of rats raises the extracellular level of dopamine accompanied with enhanced locomotion in a similar manner. Furthermore, the quantitative EEG after application of 2-methylthio ATP or… CONTINUE READING
