The MRI scanning session will start with acquisition of structural MRI brain images to be used as an anatomical reference. The acquisition of the structural MRI will last for around 6 minutes and during this time subjects are able to get familiar with the MRI procedure. Fear and arousal will decline slowly after the first minutes and prior to the fMRI paradigms. Three fMRI paradigms have been selected to probe reactivity to alcohol-related cues, monetary reward, and to measure BOLD signal fluctuations in the brain resting state. Subjects will be discharged from the inpatient unit 2 days (48 hours) after the second fMRI scan; they will be motivated to remain abstinent and returned to their previous living situation.
