Finger tapping shows that alcoholics may recruit other brain regions for simple tasks

Chronic drinking is associated with neurocognitive deficits due to neuropathological changes in the structure, metabolism, and function of the brain. One of the consequences of neuropathological brain abnormalities in the cerebellum of alcoholics has been impairment of motor functioning. A new study using functional magnetic resonance imaging (fMRI) during a finger-tapping exercise has found a weakened relationship between frontal lobe and cerebellar activity in alcoholic individuals.
