Dear Josh, at this point, and given that the boundaries between these subfields cannot really be seen in 1mm T1 scans, the algorithm assumes that all the subfields other than fimbria and fissure share the same image intensity properties. Therefore, using your own words:
"depend only on outward boundaries of the hippocampus and probability priors to determine the inner boundaries between CAs and dentate gyrus" Cheers, /Eugenio > - > > Josh > _______________________________________________ > Freesurfer mailing list > Freesurfer@nmr.mgh.harvard.edu > https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer -- Juan Eugenio Iglesias, PhD http://www.jeiglesias.com igles...@nmr.mgh.harvard.edu Athinoula A.
