FIGURE 1. Hypo- and hypermetabolic regions in PWS patients vs. healthy control subjects. These regions are displayed on surface rendered and transaxial images. Brain regions of abnormal glucose metabolism are displayed using height threshold of uncorrected P = 0.001 and extent threshold of 70 voxels, after removing age as a covariate of no interest. Numbers in each transaxial brain image indicate distance (mm) from the anterior commissureposterior commissure plane.
