Initial, habitual and compulsive alcohol use is characterized by a shift of cue processing from ventral to dorsal striatum

Abstract

In line with our hypothesis we found higher cue-induced activation of the ventral striatum in social compared to heavy drinkers, and higher dorsal striatal activation in heavy drinkers. Increased prefrontal activation may indicate that social drinkers activate cortical control when viewing alcohol cues, which may prevent the development of heavy drinking or alcohol dependence. Our results suggest differentiating treatment research depending on whether alcohol use is hedonic or compulsive.
