The principal foci of activation in this time window were estimated to the frontal regions which, along with the continued contributions from the LT cortex underlie the two overlapping functions that appeared to be engaged by this dual-level task. First, left fronto-temporal event-related theta power was sensitive to the semantic manipulation and was attenuated by alcohol (Figure 3). In both lateral prefrontal and the LT region, SW elicited significantly stronger theta power than PW (Table 1). While alcohol attenuated theta power to SW, the PW remained unaffected by intoxication. Second, the prefrontal network comprising the ACC and lateral frontal areas was sensitive to decision conflict and was also affected by intoxication (Figure 4). The AN imperative words elicited significantly stronger theta power than SW particularly under placebo in both, aIPF, F(1,21) = 10.1, p < 0.005 and pIPF, F(1,21) = 10.1, p < 0.005, but not under alcohol, F-values were 2.7 and 0.5 respectively, neither significant. Similarly, theta power estimated to the ACC was stronger to AN than to SW under placebo, F(1,21) = 4.9, p < 0.05, but not
