Top: Results of whole-brain analysis showing significant group x time interaction cluster in the posterior cingulate/precuneus (Brodmann Area 30/31/19; cluster size=241 voxels, peak voxel: x=6, y=−64, z=14; p=.023 corrected for multiple comparisons at cluster level. Extracted data are plotted to illustrate the nature of the interaction. Bottom: Results of whole-brain correlation with Bl to EOS symptom improvement within the PTSD group. The cluster is located in the posterior cingulate/precuneus/visual cortex (Brodmann Areas 30/31/18; cluster size=492 voxels; peak voxel: x=−6, y=−66, z=20; p=.013 cluster corrected). Extracted data are plotted for illustrative purposes only.
