Fig. 2: Representative spectra of control and patient pre- and postoperatively.

Basal ganglia spectra are depicted in the top row, while white matter spectra are shown in the bottom row. The chemical shift (ppm) is shown on the X axis, and the spectral data are shown in black with the LCModel fit overlaid in red. The residuals between the data and the fit are shown above each spectrum.
