Enduring enhancement in frontal cortex dopamine utilization in an animal model of amphetamine psychosis.
It is reported that in rats the repeated intermittent administration of amphetamine produces a long-lasting enhancement in medial frontal cortex dopamine utilization. This change in mesocortical dopamine activity may be involved in the behavioral sensitization produced by psychomotor stimulant drugs, and some of the cognitive abnormalities (e.g. amphetamine psychosis) associated with stimulant drug abuse in humans.
