Alcoholics' 'injured brains' work harder to complete simple tasks: Finger tapping study shows alcoholics may recruit other brain regions:

Alcoholic brains can perform a simple finger-tapping exercise as well as their sober counterparts but their brain must work a lot harder to do it, according to a Vanderbilt study released by the journal Alcoholism: Clinical & Experimental Research.
Chronic drinking is associated with abnormalities in the structure, metabolism and function of the brain. One of the consequences of these deficits is impairment of motor functioning.
The new study, using functional magnetic resonance imaging (fMRI) during a finger-tapping exercise, found that the frontal lobe and cerebellum activities were less integrated in alcoholic individuals.
