Various electrophysiological measures of the brain have been implicated in predisposition to alcohol use disorders. Evidence from twin studies suggests that a substantial proportion of the variance in electroencephalographic (EEG) patterns is genetically determined.36-39 Studies investigating the EEG of chronic alcoholics have reported the alcoholic EEG to be of lower voltage, to be deficient in a activity, to be higher in p activity, to contain some 9 activity, and to have an excess of fast activity19,40-44 Studies conducted on offspring of alcoholic fathers suggest that certain EEG variants may be potential endophenotypes for development of alcohol dependence.19,45
