Behavioral analysis showed that the AUDIT score was significantly correlated with SSRT. To explore whether regional responses to the AUDIT score (Figure 3, blue, same as Figure 2a) contribute to prolonged SSRT, we regressed SS>GS against SSRT (Table 2; Figure 3, turquoise) with inclusive masking to identify voxels with overlapping representations in linear regressions of SS>GS against SSRT and against the AUDIT score (Figure 3, cyan). The results showed that the activations of the dACC extending to SFG, left MFG, pre-SMA, and thalamus increased to shorter SSRT (more efficient response inhibition) and decreased to higher AUDIT score.
