that these high-risk subjects manifested significantly decreased ERO activity in delta (1-3 Hz), theta (4-7 Hz), and low alpha (8-9 Hz) bands during the NoGo condition, as well as reduced delta and theta activity during the Go condition. This study provided further evidence that these deficient oscillatory responses antecede the development of alcoholism [147] and perhaps could serve as effective endophenotypes in the study of alcoholism.
