Figure. Single voxel magnetic resonance spectroscopy of the motor and prefrontal cortex.

Magnetic resonance spectroscopic data were acquired from 2 brain regions as illustrated in the T1-weighted images showing voxel prescription in the (A) motor and (C) prefrontal cortices. Proton magnetic resonance spectrum acquired from each of the regions, shown in (B) and (D), respectively, highlights the target metabolites: Cho = choline; Cr = creatine + phosphocreatine; Ino = myo-inositol; NAA = N-acetylaspartate + N-acetylaspartylglutamate.
