The observed increase in medial-frontal theta activity is consistent with previous observations with go/no-go task data (Yamanaka and Yamamoto, 2009; Barry, 2009; Kamarajan et al., 2004; Kamarajan et al., 2006; Kirmizi-Alsan et al., 2006), as well as other control-related processes such as response error and feedback processing (Bernat et al., 2011; Gehring and Willoughby, 2004; Trujillo and Allen, 2007; Yordanova et al., 2004; Cavanagh et al., 2011; Cavanagh et al., 2009a; Cavanagh, et al., 2011; Cohen et al., 2007; Cavanagh et al., 2009b). This is in addition to the large number of studies demonstrating increases in traditional time-domain N2/ERN/FN components in these tasks (Pfefferbaum et al., 1985; Gehring et al., 1993; Miltner et al., 1997). Source imaging of these effects have indicated the anterior cingulate cortex (ACC) as a primary generator of these theta-related ERP components (Gehring and Willoughby, 2004; Miltner et al., 1997; Cohen, 2011; Luu and Tucker, 2001; Luu et al., 2004; Luu, et al., 2003; Wang et al., 2005; Bokura et al., 2001; Pandey et al., 2012). The observed theta increases for no-go stimuli are consistent with
