Figure 1.
Default mode network (DMN) connectivity differences between youth with posttraumatic stress disorder (PTSD) and healthy youth in the posterior cingulate cortex (PCC) seed-based connectivity analysis. Note: Respective group maps are shown as well as group connectivity differences, adjusting for age and sex. Youth with PTSD showed increased connectivity within the DMN (PCC-left inferior parietal gyrus [IPG]), but also greater anti-correlation between the PCC and multiple nodes of attentional control networks (right inferior frontal gyrus [IFG]/insula, right intraparietal sulcus [IPS], dorsal anterior cingulate cortex [dACC]/pre-supplementary motor area [SMA]). Maps are shown at a voxelwise p=.005 and minimum cluster extent of 152 voxels. “-” represents a subtraction operation; “=” represents the results of the subtraction operation; “*” represents significant differences between youth with PTSD and healthy youth for the bar graph data.
