Figure 4.

Localized ¹H spectra (thin gray lines) acquired from a control rat and a STZ-treated rat at 4 weeks. Corresponding LCModel fits to the raw spectra (thick black lines) and fitting residuals are also shown. Top panel: visual cortex; middle panel: striatum; bottom panel: hippocampus. Only the metabolites with CRLB <15% were reported. Con, control group; CRLB, Cramér–Rao lower bound; Glx, glutamate + glutamine; GSH, glutathione; Ins, myo-inositol; NAA, N-acetyl aspartate; STZ, streptozotocin; Tau, taurine; tCr, total creatine; tPC, (glycerophosphocholine+phosphocholine).
