nervous system
• the inhibitory effect of carbachol, a hydrolytically stable ACh analog, is not observed in striatal membranes exposed to the D1 receptor agonist, SKF82958.
|
behavior/neurological
• enhanced activity at the highest dose (30 ug/kg) of SKF82958, a D1 receptor agonist
|
• significantly more active following a high dose (2 mg/kg) of amphetamine
• develop enhanced amphetamine induced behavioral sensitization
|
• significantly more active following exposure to a high dose (10 mg/kg) of cocaine
• develop enhanced cocaine induced behavioral sensitization
|
• haloperidol induced and risperidone induced catalepsy are attenuated
|
• enhanced activity at the highest dose of SKF82958, a D1 receptor agonist
• enhanced activity at high doses of cocaine (10 mg/kg) or amphetamine (2 mg/kg)
|
homeostasis/metabolism
• basal dopamine efflux in the nucleus accumbens of is increased two- to three-fold
• absolute amphetamine-induced dopamine efflux was significantly enhanced at the 120 min time point, as compared to control mice
• however, the relative percent increase induced by amphetamine exposure is not different from controls
