that research on the acute effects of alcohol on theta oscillations has been exceedingly limited (Krause et al., 2002). Fifth, previous EEG studies using cognitive tasks have observed increased theta power during the engagement of executive functions (McEvoy et al., 2001; Jensen and Tesche, 2002; Brier et al., 2010) particularly in prefrontal areas (Kovacevic et al., submitted). Consistent with the notion that memory processes are reflected in theta oscillations (Klimesch, 1999; Klimesch et al., 2001), language studies have shown that the theta band is sensitive to the lexical-semantic retrieval (Bastiaansen et al., 2005, 2008).
