top. Significant (p = 0.008) Infusion × FHA interaction in the [Inh > Go] BOLD contrast within the a priori right anterior/inferior prefrontal ROI (defined by independent reference sample, inset/green arrow and Figure 1). The BOLD contrast was significantly affected by alcohol in FHN (p = 0.002), but not FHP (p= 0.292). FHP= family history positive for alcoholism; FHN= family history negative for alcoholism. Error bars= standard errors of the mean. bottom. For reference, voxel-wise display of individual group/condition effects (left), as well as the Infusion × family history interaction (right) at its peak location (y = 54mm); display threshold, p< 0.005, uncorrected.
