Corticotropin-releasing factor receptor blockade enhances conditioned aversive properties of cocaine in rats.

abstract：:Amphetamine stimulates locomotor activity, in large part by activating central dopaminergic systems. Serotonin shares on overlapping distribution with dopamine and has been shown to modulate dopaminergic function and dopamine-mediated behaviors. The present study examined whether increasing serotonergic function, via ...
