[A] sample MR spectrum from left pregenual anterior cingulate cortex (pACC) with principal resonances for N-acetyl-aspartate+N-acetyl-aspartylyglutamate (NAA+NAAG = tNAA), glutamate+glutamine (Glu+Gln = Glx), creatine+phosphocreatine (Cr), choline-compounds (Cho), and myo-inositol (mI). [B] parasagittal, coronal and axial-oblique T1w MRI sections showing position of MRS acquisition volume (“voxel”) for left pACC. [C] the same for left anterior middle cingulate cortex (aMCC) voxel. [D] The same for left thalamus voxel. Voxels were acquired at homologous sites in the right cerebral hemisphere.
