contrast to the expected pattern, AU youth who transition to having blackouts showed an overall greater pattern of task-relevant response in salient frontal regions. The authors interpret these data (greater activation in light of equivalent behavioural performance) as suggestive of functional compensation. In other words, B+ youth might need to recruit more inhibitory processing areas to successfully inhibit behaviour. In terms of the longitudinal piece, it is worthwhile to note that greater right and left middle frontal brain regions in AU youth predicted a two-fold increase in risk for experiencing blackouts in the following five years. Thus, the differential pattern of frontoparietal inhibition processing in AU B+ youth may present future difficulties with successful inhibition.
