Regional norepinephrine response to amphetamine using dialysis: Comparison with caudate dopamine

Abstract

The response of extracellular norepinephrine to the acute administration of amphetamine was assessed, using dialysis, in prefrontal cortex and hippocampus in awake, behaving rats. Norepinephrine exhibited a pronounced and rapid dose- and time-dependent increase in response to 0.5 and 2.5 mg/kg amphetamine, which corresponded closely to the time course of the behavioral profile. These results are consistent in with a possible role for norepinephrine in the behavioral response to amphetamine.
