Figure 8. Brain regions that showed differences in bilateral IPS connectivity for addition and subtraction problems between DD and TD groups.

Figure 8

(A) For both groups the bilateral intraparietal sulcus (IPS) was connected to multiple frontal, parietal and occipital regions (shown in orange). However, children with developmental dyscalculia (DD, yellow) showed greater extent of connectivity than typically developing children (TD, red). Threshold used for illustration: p < .001. (B) Compared to TD children, children with DD have greater IPS connectivity with bilateral angular gyrus (AG), left supramarginal gyrus (SMG), right middle frontal gyrus (MFG), right inferior frontal gyrus (IFG), posteriomedial cortex (PMC) and ventral medial prefrontal cortex (vmPFC). Threshold as in Table 3, color bar indicates t-score. (C) ROI profiles revealed that connectivity differences where driven by positive connectivity in the DD group.
