Acute pharmacological blockade of alpha1 adrenoreceptors (ARs) attenuates the locomotor response to amphetamine (LRA). We took a genetic approach to study how norepinephrine (NE) signaling modulates psychostimulant responses by testing LRA in dopamine beta-hydroxylase knockout (Dbh-/-) mice that lack NE. Surprisingly, Dbh-/- animals were hypersensitive to(More)
The alpha2-adrenoreceptor (AR) is the most investigated noradrenergic receptor with regard to modulation of seizure activity. However, because of the complexity of multiple alpha2-AR subtypes and their distribution, the exact role of this receptor in modulating seizure activity is not clear. alpha2A- and alpha2C-ARs function as both autoreceptors(More)
