Fig 6. Functional connectivity between lateral frontopolar cortex (FPC) and dorsal anterior cingulate cortex (dACC).

Fig 6

(A) Psychophysiological interactions (PPI) analyses. The PPI used the right lateral FPC as a seed (sphere of diameter = 10 mm centered at [x,y,z] = [42,44,19]). The functional connectivity between right FPC and dACC increased when group size increased (P < 0.05, family-wise error [FWE] corrected within small volume correction [SVC]). Error bars represent the standard error of the mean (SEM) (**, P < 0.001). (B) Between-subject regression analysis considering the individual difference in the relative credibility of social information (Δσ) as a covariate for the modulation of connectivity between dACC-FPC when presented with social information of the large versus the small group (P < 0.05, FWE corrected within SVC). The scatter plot was not used for statistical inference (which is carried out in the SPM framework). It is shown solely for illustrative purposes.
