Main effect of PTSD Diagnosis on regional cerebral metabolic rates for glucose (rCMRglu). This image shows resting rCMRglu in dorsal anterior cingulate/mid cingulate cortex that is greater in trauma-exposed twins with PTSD and their unexposed identical co-twins, compared with trauma-exposed twins without PTSD and their identical co-twins. FDG data are superimposed on a standard SPM2 T1 template and displayed according to neurological convention. The accompanying bar graphs present group means; error bars represent standard error of the mean. MNI=Montreal Neurological Institute
