Local cluster‐level maxima of blood oxygen level dependent fMRI signal change during 2‐back condition versus 0‐back baseline condition between carrier group (n = 22) and noncarrier group (n = 35)

Coordinates are listed in Talairach and Tournoux (1998) atlas space. BA is the Brodmann area nearest to the coordinate and should be considered approximate. The significance level is given in Z‐values and cluster size in number of voxels for P < 0.001 (corrected by Monte Carlo simulations), extent threshold = 26 voxel.
