Regions showing a significant linear increase of cerebral activation related to WM load in both controls and pretreatment OSA patients (P < 0.05 FWE corrected 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), hIP = human Intra-Parietal area, SMA = supplementary motor area, IFG = inferior frontal gyrus.
