Note: Results are reported at p < .01, 128 voxels. MNI coordinates are labeled according to the Harvard-Oxford atlas. IPS is defined based on the Juelich atlas. For each cluster, 3 sub-peaks are reported which are more than 8mm apart. MD = children with mathematical disabilities, TD = typically developing children, IFG = inferior frontal gyrus, IPS = intraparietal sulcus, ITG = inferior temporal gyrus, MFG = middle frontal gyrus, MTG = middle temporal gyrus, SFG = superior frontal gyrus, SMG = supramarginal gyrus, SPL = superior parietal lobule.
