Localized 1HMRS spectra processed by LCModel software from the occipital cortex (top) and parietal cortex (bottom) with the appropriate locations in parietal and occipital cortex shown on corresponding T1-weighted MR images. Labeling of the spectral signatures for glutamate (Glu), N-Acetyl-Asparate (NAA), Glutamate + Glutamine = GLX, total choline (tCho), total creatine (tCr), myo-inositol (mI) and macromolecules (MM). The raw (black) and fitted (solid red line) spectrum as well as the remaining baseline (stippled red line) are shown in each of the spectra.
