Examples of DAWM on FLAIR MRI slices. Transversal slices of 1.5T FLAIR MRI scans. For visualization only, brains were skull-stripped and DAWM is shown with dotted lines (occipital DAWM is red, parietal DAWM is orange). Top row images (25% of lobar WM) show larger, more confluent configurations of DAWM, extending beyond the slices shown here.
