Experiment 1: Voxel tissue content and proton magnetic resonance spectroscopy (1H MRS) metabolite levels in midline pregenual anterior cingulate cortex (pACC) voxel.

*pvs. controls controls analysis-of-covariance covarying gender and vol% WM on rank-transformed (non-parametric) data, Bonferroni-corrected for multiple comparisons with a priori hypotheses.SD = standard deviation, GM = gray matter, WM = white matter, CSF = cerebrospinal fluid.tNAA = N-acetyl-aspartate + N-acetyl-aspartyl-glutamate, Glx = glutamate + glutamine, Cr = creatine + phosphocreatine, Cho = choline compounds, mI = myo-inositol.
