Ala, alanine; Cr, creatine, PCr, phosphocreatine; GABA, γ-aminobutyric acid; Gln, glutamine; Glu, glutamate; GSH, glutathione; Gly, glycine; myo-Ins, myo-inositol; Lac, lactate; NAA, N-acetyl-aspartate; NAAG, N-acetyl-aspartate-glutamate; Tau, taurine; PE, phosphatidylethanolamine; Mac, macromolecule; GPC, glycerophosphocholine; PCho, phosphocholine. All concentrations, except ratios, are in mmol/kg. Number of animals is indicated in parentheses. Only metabolites with CRLB of less than 45% in all animals are presented. The changes are calculated compared to sham and displayed with specific oriented arrows (‘↓’ as decrease and ‘↑’ as increase). The number of ‘*’ represent statistically significant levels of p = 0.05, 0.02, 0.01 and 0.001.
