  • MNI = Montreal Neurological Institute; PTSD = posttraumatic stress disorder.

  • * Significant at p < 0.05, family wise error–corrected, whole-brain cluster level–corrected.

  • Significant at the cluster level, but does not survive whole-brain correction.

  • Small volume corrections significant at p < 0.05.
