  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 exact calculation versus exact control condition are specified. Listed activated brain regions had been subjected to a FDR correction at p < 0.005 with a minimum number of 10 voxels.
