Significant (p < 0.01, cluster > 756 microliters) group × time interactions in BOLD response contrast to no-go relative to go trials were seen in 5 clusters in frontal, parietal, cerebellar, and subcortical brain regions. Graphs are shown for two of these regions: right middle frontal gyrus and right inferior parietal lobule. Future heavy drinkers showed less BOLD response at baseline in several brain regions, but greater BOLD response at follow-up after the initiation of heavy drinking, compared to continuous non-drinking controls. MFG = Middle Frontal Gyrus, L = Left, * p <.05, ** p <.01.
