Creating reference areas by mirroring CMB location through the midsagittal plane.
The reference areas were created by automatically placing a marker in the contralateral hemisphere by mirroring the location of the CMB through the midsagittal plane (solid blue line), which was automatically generated.39 This way, each cortical CMB corresponded with one reference location at the same position in the contralateral hemisphere. The reference sites were visually checked, and if the automatically placed marker was not within the cortex, it was manually moved to the closest location within the cortical ribbon. Of note, the figure displays a 2D schematic example of the mirroring: the mirroring procedure was performed in 3D in the analysis.
