Cortical map of average shortest distances from the GM/WM interface to the nearest CMB. To generate this map, the distance between each cortical mesh vertex and the closest CMB was calculated for each subject, and this distance was plotted on the cortical surface. The subjects’ cortical maps were transformed to a common average template (atlas) and averaged over to generate the map above. CMBs were localized near the cortical surface within the lateral and medial aspects of the frontal and parietal lobes, orbitofrontal cortex, the temporal lobes, the insulae, and the right temporo-parieto-occipital junction. Within these cortical regions, the average shortest distance between the cortex and the nearest CMB was μ ± σ = 7.1 ± 1.8 mm
