摘要：An imbalance between noradrenergic and dopaminergic systems is implicated in hyperactivity disorders, such as attention deficit/hyperactivity disorder (ADHD). We previously showed that the explosive jumping behavior elicited by intermittent rapid eye movement sleep deprivation (REMSD) may serve as a useful model of ADHD (see [ Biogenic Amines , 20, 99—111]). Here, we investigated whether intermittent REMSD might cause changes in monoamine turnover in the mouse forebrain. Our main findings were as follows. Intermittent REMSD led to a significant decrease in dopamine turnover and a significant increase in noradrenaline turnover in the frontal cortex. The latter effect, but not the former, was attenuated by atomoxetine, which is used clinically to treat ADHD symptoms. These results suggest (a) that intermittent REMSD induces hypernoradrenergic and hypodopaminergic states within the frontal cortex, and (b) that the therapeutic effects of atomoxetine may include an inhibition of this hypernoradrenergic state.
