Results of the ICCp analysis.

Coordinates of the peak voxel	Number of voxels	Cluster p-FWE	Peak p-FWE	Peak p-uncorr	Location
+02 +40 +54	184	0.0000	0.9999	< 0.001	Bilateral medial superior frontal gyrus
+34 +28 +00	68	0.0106	0.0390	< 0.001	Anterior right insula
−20 +32 +52	62	0.0209	1.00	< 0.001	Left superior frontal gyrus

The table displays the coordinates of the peak voxels, the number of voxels covered by the ICCp cluster, and their location in the brain (high threshold on voxel-level: p < 0.01 uncorrected; cluster threshold: p < 0.05 FWE corrected, only the negative correlation of the ICCp index with age was computed).
