Effect of impulsivity on craving and behavioral reactivity to smoking cues.

abstract：:Neither acquisition learning nor 24-h retention was significantly altered by 6-hydroxydopamine intracerebral injections which depleted forebrain noradrenaline (NA) to less than 5% of control values. The absence of passive avoidance impairment cannot be ascribed to functional recovery following the lesion (indicated by...
