Alcohol Intoxication Effects on Simulated Driving: Exploring Alcohol-Dose Effects on Brain Activation Using Functional MRI
""The areas most profoundly affected by alcohol were the orbital frontal and anterior cingulate areas, which help control motor functions. The medial frontal regions of the brain involved in making decisions, and working memory, were not affected until the person was beyond the legal limit of intoxication. A function of working memory might be to find one's way home, the researchers said.
Impairment of the cerebellum area of the brain, which related strongly to speeding, was clearly correlated with the alcohol dose. Changes in the frontal and parietal cortex, which govern alertness and attention, were correlated with weaving while driving. ""
