FIG. 2.

Brain areas showing less FDG metabolism (“blue”) and GM (“green”) as a function of more CSF SOD1. Numbers below each brain slice represent the sagittal MNI coordinates of the slice. Overlapping areas showing both less FDG metabolism and GM are teal. The GM graph depicts the relationship at the maximal voxel in the left supplementary motor area (−9, −10.5, 78) and the FDG graph depicts the relationship at the maximal voxel in middle cingulate gyrus (4, −2, 44). FDG, fluorodeoxyglucose; GM, gray matter. Color images are available online.
