Fig. 1. PAG connectivity and alcohol expectancy.

Fig. 1

a Whole-brain multiple regression showed a negative correlation between PSP and PAG (far left in green) connectivity with the precentral gyrus (PrCG), postcentral gyrus (PoCG), and paracentral lobule (PCL) (right, blue). b AUDIT scores were positively correlated with PSP scores (left) and negatively correlated with averaged connectivity strength of PAG with PrCG, PoCG, and PCL (right). c Mediation analysis showed two significant models in which PSP bidirectionally mediated the negative relationship between PAG connectivity and AUDIT scores. NB: all partial correlations in this and other figures show regression residuals of parameter estimates of connectivity, PSP, and AUDIT scores after the effects of age and sex had been removed. **p < 0.01.
