Fig. 1.

(a) Skull stripped T₁-weighted MRI data recorded from a single MP subject demonstrating typical ACC MRS voxel positioning (red box) on axial (top panel) and sagittal (bottom panel) image slices. (b) 2D J-resolved ¹H MRS data recorded from the MRS voxel shown in (a). The raw 2D MRS data (real component) is shown in the top panel with the black box depicting the region used for spectral fitting. The resulting 2D fit as calculated using ProFit is shown in the bottom panel and tentative signal assignments are provided. The color bars to the right show contouring amplitudes and signal phase. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
