  1. Note: One patient was excluded in NPPE group (n = 14) due to different acquisition parameters for the analysis
  2. Post-hoc analysis for caudal anterior cingulate area showed that the significant differences were between HC and PPE (p = 0.042); for the left parahippocampal area, significant differences were evident between HC vs NPPE (p = 0.014) and NPPE vs PPE (p = 0.040); for the left superior temporal and for postcentral area there were no significant differences between groups
