Several studies have examined ERO measures in alcoholism, including evoked, induced, and total power using various tasks and paradigms and found lower power in different frequency bands (Andrew and Fein, 2010, Jones, Porjesz, 2006a, Jones, Porjesz, 2006b, Kamarajan, Porjesz, 2006, Kamarajan, Porjesz, 2004, Kamarajan, Rangaswamy, 2008, Kamarajan, Rangaswamy, 2012, Padmanabhapillai, Porjesz, 2006a, Padmanabhapillai, Tang, 2006b, Rangaswamy, Jones, 2007). Findings of the present study of group differences are largely consistent with the previously reported literature (please refer to points #3-4 under the subsection 4.1 above). In addition, compared to the studies mentioned above, the present study also found lower evoked slow alpha power in both Go and NoGo conditions and lower evoked fast alpha power in only the NoGo condition in alcoholics.
