Fig. 4.

Group-level results of parcellation solutions for the bilateral BA10 shown on the MNI152 brain. The group parcellations images were created based on areas of the frontal pole that showed overlap across subjects. a In the two-cluster solution, the medial cluster is shown in red and the lateral cluster is shown in green. The images are thresholded at 75 % (26/35) of all subjects. The left medial had a centre of gravity (COG all coordinates are in MNI space) at (−6, 58, −12), and the right medial cluster had a COG at (8, 58, −6). The left lateral cluster had a COG at (−34, 50, 10), and the right lateral had a COG at (36, 50, 14). b In the three-cluster solution, the medial cluster is shown in red, the rostral cluster is shown in blue, and the lateral cluster is shown in green. The images are thresholded at 75 % (26/35) of all subjects. The medial cluster had a COG at (−12, 64, 12) on the left, and at (20, 62, 4) on the right. The rostral cluster had a COG at (−6, 58, −12) on the left and the COG at (8, 58, −6) on the right. The lateral cluster had a COG at (−34, 50, 10) on the left, and the COG at (36, 50, 14) on the right
