The relative value of alcohol may be encoded by discrete regions of the brain, according to a study published in Neuropsychopharmacology. Using functional magnetic resonance imaging (fMRI), Dr. James MacKillop and colleagues examined brain activity in 24 male volunteers, who were heavy drinkers, while they were deciding whether or not to drink alcohol priced at various levels. Their findings identify unique motifs of brain activity that may contribute to the pathologically increased value that addicted individuals place on alcohol.
