Yes, based on the surfaces. We use Anderson Winkler's truncated pyramid
method.

The volume between the surfaces is calculated

Ian,
You can use the mris_anatomical_stats command with the -b option. E.g.,
mris_anatomical_stats -b subjectid lh
will give you a tabular output containing the total gray matter volume in
the 3rd column:
128449 86239 *243375 *2.588 0.876

Can you describe how the FS stat Total cortical gray matter volume is
calculated from the files in the freesurfer subject directory? Is there
an mgz file where each voxel has an estimated percentage grey matter
here as the
