WebHere we confirm the behavioral phenotypes reported by Menalled et al [1], and extend the characterization to include brain volumetry, striatal metabolite concentration, and early neurophysiological changes. The overall reproducibility of the behavioral phenotype across the two independent laboratories demonstrates the utility of this new model. WebIntroduction. Brain aging is a physiological process occurring with age leading to atrophy of different structures. Brain volumetry using magnetic resonance (MR) data has been used for many years allowing for in vivo assessment of the size of brain structures. The most commonly applied methods are region-based volumetry (RBM) or voxel-based …
