NMDA receptor antagonism: escalation of aggressive behavior in alcohol-drinking mice.

abstract：:This study examined whether the anticholinergic potency of the clinically superior antipsychotic drug clozapine contributes to clozapine's anatomically-selective functional inhibition of the mesolimbic dopamine (DA) system, using an electrical brain-stimulation reward (BSR) paradigm in rats that has been previously sh...
