Figure 6 From: The neurochemical basis of human cortical auditory processing: combining proton magnetic resonance spectroscopy and magnetoencephalography MR spectroscopy of the auditory cortex. (A) Anatomical transverse MR image of the left auditory cortex with the superimposed borders of the MRS voxel (1.5 × 1.5 × 1.5 cm3). The image shows the anterior borders of the voxel, which extends 1.5 cm in the posterior direction. (B) 1H-MRS spectrum from the auditory cortex of a single subject. NAA denotes N-acetylaspartate; Glx, glutamate/glutamine; Cr, creatine/phosphocreatine; Cho, choline-containing compounds. The original and the fitted spectrum (using the linear combination model, black line) are displayed.Back to article page
