From top to bottom, cerebral regions showing significantly different parametric effects of WM-load in pretreatment OSA vs. posttreatment OSA within, and outside, the commonly activated regions (a and b, respectively), and in posttreatment OSA vs. pretreatment OSA within, and outside, the commonly activated regions (c and d, respectively) (P < 0.001 uncorrected for multiple comparisons, minimum cluster size K = 4 voxels). H = Hemisphere, L = Left, R = Right, BA = estimated Brodmann area, ATp = most probable anatomical regions (where available) in the Anatomy toolbox [Eickhoff et al., 2005; asterisks denote assignment], K = cluster-extension in number of voxels (2 × 2 × 2 mm³), SMA = supplementary motor area, IFG = inferior frontal gyrus.
