Example spectra of PRESS & MEGAPRESS measurement in the occipital cortex and right thalamus. Abbreviations: Example spectra of a single patient using PRESS (left) and MEGAPRESS (right), with voxel placement in the occipital cortex (upper row) and right thalamus (bottom row). GABA = gamma-amino-butyric acid, GLX = glutamate/glutamine, MegaPress = Mescher-Garwood-Point Resolved Spectroscopy, OCC = occipital cortex, PRESS = Point-RESolved Spectroscopy, ppm = part per million, THAL = Thalamus
