Amphetamine-induced appetitive 50-kHz calls in rats: a marker of affect in mania?

abstract：:The novel dopamine autoreceptor antagonists (-)-DS 121 and (+)-UH 232 were tested for their ability to alter cocaine self-administration behavior in rats reinforced on a progressive ratio (PR) schedule. (-)-DS 121 (15 mg/kg) and (+)-UH 232 (30 mg/kg) produced significant decreases in breaking point. (-)-DS 121 produce...
