College Age Drinkers: Reduced Brain Function

This shows a direct comparison between activation levels in each part of the alcoholics' brains relative to that of the nonalcoholics'.  You can see (from the Top View-ear level and Side View-down middle- pictures) that an area in the back of the brain on the Right is less active in alcoholics than in controls.  There were also areas in the front part of the brain that were under-activated in alcoholic youth during this task.  Warm colors show where alcohol-dependent youth had less activation than comparison youth during a memory task.
