Fig. 4: Predictive Effect of SN Connectivity on Post-trauma Stress Levels.

Decreases in the coupling between the overall SN and hub regions of the DMN (i.e., posterior cingulate cortex (PCC)/precuneus (PCu)), and postcentral gyrus and intracalcarine cortex as a function of acute-stress induction predicted the higher levels of perceived stress after trauma exposure. The arrow indicates functional connectivity changes between the overall salience network (i.e., coefficients extracted using the depicted network mask thresholded at Z > 3) and clusters in PCC/PCu, visual cortex, and somatosensory cortex.
