In vivo 1H NMR spectroscopy at 9.4T was used to investigate the neurochemical changes in the striatum and cerebral cortex of the Q140 knock-in mouse model of Huntingtons disease (HD). Mice were scanned repeatedly during the their lifespan (6 weeks 24 months). More than 300 spectra were acquired. Most significant changes were observed for Gln, PCr, PE and Lac and were mostly localized in mouse striatum, which more closely mimic symptoms found in HD human patients.
