Representative voxel placements. Representative voxel placements (a and d) and corresponding thalamic (b-c) and cerebellar (e-f) spectra. Assignments: 1, Creatine (−2CH2-); 2, Glx (−2CH-); 3, Choline (−N (CH3)3); 4, Creatine (−N (CH3)); 5, GABA+ (−4CH2-); 6, tNA (−3CH2-); 7, Glx (−4CH2-); 8, tNA (−2CH3); 9–11, Macromolecules and lipids, −CH2-. Abbreviations: Glx, glutamate+glutamine; GABA+, γ-Aminobutyric acid (+macromolecule signal); tNA, total N-acetylaspartate (NAA + NAAG)
