  1. Anatomical localization, Talairach coordinates, T scores of significant activated voxels and cluster size of activated regions in children with DD and control children during magnitude comparison versus rest are listed. Activated brain regions had been subjected to a FWE correction at p < 0.05 with a minimum number of 10 voxels.
