The surface area is the actual area of the surface. I think you may be
thinking of the jacobian, which measures the amount of stretching needed
to register with the surface atlas. Total cortical volume is available
from the "header" of the aseg.stats file, and that is a surface-based
measure.

Hello,
As I understand it, the surface area measure is not a real surface
area measure. It is more a measure of how much the brain has to be
stretched in order to get into a common space. My question is that if
the cortical volume is calculated by multiplying the thickness and the
surface area (
