Table 3. Correlations between arithmetic fluency and typically arithmetic-associated parietal regions for the voxel-based morphometry analyses.

Note: SPL = Superior Parietal Lobe; AG = Angular Gyrus; SMG = Supramarginal Gyrus; L = Left; R = Right. The used atlases only consider voxel-based morphometry possible on gyri, hence the absence of the intraparietal sulcus in this analysis, yet all typically arithmetic-associated areas that surround the intraparietal sulcus (i.e., postcentral gyrus, superior parietal lobe, angular gyrus, and supramarginal gyrus) were included. The critical p-values for Bonferonni correction for multiple comparisons is p < .001.
