Hi Feng
they are slightly different measures so which one you use really depends
on your biological hypothesis.
For thickness there are multiple measures wit
l the vertics. And of coz, I can compute the total
thickness in each region like the area (summation of each vertex's thickness in
each region), right?
Best,
Feng

Dear Freesurfer experts,
I have a question about the calculation of surface area. The cortical thickness
is the distance between the pial and white matter. But, what about the surface
area? Calculation based on pial or white matter? Or average the area of both of
them.
Is the area of each ver
