Fig. 1. Positive Correlation between Change Ratio of IA and RSFC from Left AIC to Left DLPFC and Right SMG.

Fig. 1

Significant positive correlations were observed between the change ratio of IA and increased RSFC from the left AIC to (A) the left DLPFC (-40 46 32) (Pearson’s r = 0.84, p < 0.001), and (B) the right SMG (-12 16 42) (Pearson’s r = 0.79, p < 0.001), illustrated by the blue and the red scatter plots on the right side, respectively. Vertical axes represent increased RSFC at peak voxel in each cluster, and horizontal axes indicate a change ratio of IA (i.e., Post IA/Pre IA). The statistical threshold was set at p < 0.001 and corrected to p < 0.05 for multiple comparisons using cluster size.
