title: Cocaine stimulant effects vary with cocaine levels in medial prefrontal cortex.
abstract: Rats treated with 10 mg kg-1 cocaine exhibited hyperlocomotion. Individual variation in the magnitude of this response was not correlated with serum cocaine concentration. Brain cocaine concentration, particularly in the medial prefrontal cortex, was highly correlated with the cocaine-induced locomotor stimulant effect. These findings indicate that variation in the uptake of cocaine into the brain is a critical variable in determining individual variation in its stimulant effects.
