Use pial or white surface area of FreeSurfer?

Hi, all. Surface area is a commonly used metric. Unlike thickness and volume, area could be calculated based on white surface or pial surface in FreeSurfer. I don’t know which one should be used for analysis. I believe the pial surface area is more sensitive to brain changes such as gray matter atrophy. But the white surface area is the default in FreeSurfer and thus probably the one used in papers.
