Included are probability maps for each of the manually labeled lateral frontal sulci across 72 individual hemispheres. These probability maps are available as maximum probability maps (MPMs) tresholded at > 33% subject overlap for a given vertex, or as raw overalp maps. They are registered to the fsaverage (https://surfer.nmr.mgh.harvard.edu/) template surface.
