Notes. L = left hemisphere, R = right hemisphere. Atlas coordinates are listed in the standard space of the Montreal Neurological Institute (MNI). Volumes are in voxels (1.5mm × 1.5mm × 1.5mm). All clusters are significant at p < .001 (uncorrected), k ≥ 30. CAPS – Clinician Administered PTSD scale, AHC – Amygdala-Hippocampus Complex.
