Our results, as well as the Jones et al. (2006) and Rangaswamy et al. (2007) studies all show that δ EROEVK power and δ and θ EROTOT power discriminate the groups10. There are both similarities and differences across studies in the scalp locations of these findings. We and Rangaswamy et al. (2007) find δ EROEVK power at parietal sites discriminates the groups, while Jones et al. (2006) reported δ1 EROEVK power frontally and the δ1 EROTOT power centrally provided the best group discrimination. For θ EROTOT power, we and Rangaswamy et al.(2007) found best discrimination at central sites, while Jones et al. (2006) found best discrimination frontally. In all three studies, power was reduced in the alcoholic group (LTAAs or active alcoholics or high-risk of alcoholism) compared to control group for all measures.
