FIGURE 4.

Partial spearman correlations between threat vigilance and functional connectivity (ρ; adjusting for age, sex, and mean motion). (a) Heatmap of correlations before (lower triangle) and after (upper triangle) global signal regression (GSR). **p < .05, Bonferroni‐corrected across 45 edges; *p < .05, uncorrected. Only the left amygdala‐periaqueductal gray connection survives correction regardless of GSR. (b) Glass brain plot of uncorrected correlations (p < .05 uncorrected with GSR). BNST, bed nucleus of the stria terminalis; PAG, periaqueductal gray; dmPFC, dorsomedial prefrontal cortex; vmPFC, (anterior) ventromedial prefrontal cortex; sgACC, subgenual anterior cingulate cortex
