Differential vulnerability to relapse into heroin versus cocaine-seeking as a function of setting.

abstract：RATIONALE:The amygdala and insular cortex are integral to the processing of emotionally salient stimuli. We have shown in healthy volunteers that an anxiolytic agent, lorazepam, dose-dependently attenuates activation of limbic structures. OBJECTIVE:The current study investigated whether administration of a selective s...
