Figure 4.

When tested in an independent dataset, the boundary map-derived parcellation is more homogenous than any other parcellation, and does better relative to its null model than any other parcellation. Top: parcel homogeneities of each competing parcellation when tested in Dataset 2. Bottom: average homogeneity across parcels of each parcellation (red dots) compared with the average homogeneity across parcels of each of 1000 null model iterations (black dots), which vary in homogeneity because of differing parcel sizes. ***indicates the parcellation was more homogenous than all of its 1000 null model iterations (i.e., P < 0.001); *indicates the parcellation was more homogenous than at least 950 of its null model iterations (P < 0.05).
