Table 2.
Listed are the peaks of significant connectome-wide associations related to full-scale IQ for Scans 1 and 2. Peaks were found using AFNI's 3dExtrema by setting a voxel-level threshold of Z > 1.65 and a minimum distance of 20mm between peaks. Abbreviations: H, hemisphere; R, right; L, left; BA = Brodmann Area.
