Dear Freesurfer experts, I highly appreciate if anybody clarify how Freesurfer calculate cortical thickness and gray matter volume. If the cortical thickness of e.g. precentral gurus is measured as the closest distance from the gray-white boundary to the gray-CSF boundray at each vertex on the tessellated surface (Fischl and Dale. 2000). How the gray matter volume for the precentral gyrus was measured?
Thank you for any clarification!
John
