Relative cerebral glucose metabolism (rCMRglc) associated with eveningness during wakefulness (A) and REM sleep (B) in combat-exposed military veterans with posttraumatic stress symptoms. Sagittal sections correspond to the x-coordinates of the peak voxel for each cluster of interest. Clusters during wakefulness were centered in the precuneus/posterior cingulate, brainstem, and precentral gyrus/inferior parietal lobe (left to right). Clusters during REM sleep were centered in the precuneus/posterior cingulated and brainstem.
