We did not find a main effect of group or emotion on P160 amplitude, consistent with Maurage et al. (2007b, 2008a, 2008c). There has been one report of an interaction effect of electrode site and group on P1 amplitude to EFE, with higher amplitude P1 in temporal region for NAC but not for alcoholics (Maurage et al., 2007b).
