Overview of brain activation peaks in the contrasts {SSD control condition minus rest}, {SSD localization minus SSD control, masked (inclusive) with SSD Localization minus rest}, and {SSD orientation minus SSD control, masked (inclusive) with SSD Orientation minus rest} from random-effect analysis (at , FDR corrected). Coordinates are reported in MNI space, as given by SPM2, and correspond only approximately to Talairach and Tournoux space [21]. BA: Brodmann area. () belonging to the same voxels cluster.
