a Box-and-whisker plots showing Normalized sulcal depth for each of the 12 LPFC sulci in the Discovery sample for the left (LH) and right (RH) hemispheres. b Same as in (a), but for the Replication sample. Repeated-measures ANOVAs revealed that tertiary sulci (orange) were shallower and more variable than primary sulci (blue) in both samples (ps < 0.001). Horizontal lines represent median values and whisker lines represent the 1st and 3rd quartiles. Values falling outside of this range are represented as black dots. Source data are provided as a Source data file.
