Location of the 1H-MRS voxels (top) and a representative spectrum (bottom). The top panel shows sagittal views of voxel placement over the anterior cingulate (left), posterior cingulate (center), and cerebellum (right). The dimensions of the respective voxels were: 25 x 25 x 25 mm3 in the anterior cingulate cortex (ACC) and posterior cingulate cortex (PCC) and 20 x 40 x 20 mm3 in the cerebellum.
