  1. Anatomical localization, Talairach coordinates, T scores of significant activated voxels and cluster size of activated regions with a minimum number of 10 voxels in children with DD (FDR p < 0.01) and control children (FWE p < 0.05) during approximate calculation versus approximate control condition are listed.
