Differential effects of clorgyline on sensitization to quinpirole in rats tested in small and large environments.

abstract：RATIONALE:Convergent evidence shows that alcohol exerts its effects on social behavior via modulation of amygdala reactivity to affective stimuli. Given that affective processing involves dynamic interactions between the amygdala and the prefrontal cortex (PFC), alcohol's effects are likely to extend beyond regional ch...
