Results of cross-frequency spatial clustering. Leftmost column: elbow criterion definition. Elbow curve and parameter selection. Second to fourth columns: Spatial clustering of cross-frequency rsFC local maxima across all frequency bands for K = 7. Left, top, and right sagittal surface brain renderings with clusters 1 (red), 2 (yellow), 3 (green), 4 (blue), 5 (orange), 6 (purple), and 7 (pink disks). All maxima belong to the vLN (orange background), except those marked with an asterisk (*). Anatomical annotations are not indicated on the maxima due to their large number but are listed in Table 3.
