In sum, the magnitude of event-related theta power was sensitive to the two functions manipulated by the double-duty lexical decision task. First, theta estimated to the left-lateralized fronto-temporal areas reflected lexical-semantic retrieval which was selectively attenuated by alcohol intoxication. Second, a highly overlapping prefrontal network comprising lateral prefrontal and ACC was sensitive to decision making and was also affected by intoxication, in agreement with previous studies indicating that alcohol’s effects are deleterious to executive functions.
