Regions tabulated show significant (p < 0.001, cluster size > 20) signal increases for experimental task versus control task. N refers to the number of significant voxels in each cluster, Z to the Z statistic value for each peak, and x, y, z refer to the distances in mm from the origin in Talairach space.
