Dear Bruce et al.,
Submitting a paper in which I use freesurfer for the analysis of the
auditory cortex, I was asked how freesurfer actually takes individual
boundaries (e.g. of Heschl's gyrus) into account? Both atlases (Desikan and
Destrieux) are based on about 10-20 subjects. How are these boundaries
transferred to other subjects? As far as I understood the description of
freesurfer there aren't any templates (or some kind of masks) which are
put on the subjects to analyse. What's the "secret" or principle behind
the individual analysis to receive reliable data for every ROI of every
subject (in a nutshell)?
Thanks in advance, best wishes,
Holger
