Dear Frederic,
I’ll defer to Jean Augustinack (CCed) for a more granular answer (pun
intended), but here are my initial thoughts.
1. You can find the definition in Table 2 of the paper, which is open
access: https://www.sciencedirect.com/science/article/pii/S1053811915003420
2. Yes.
3. Both. We initially subdivided but it was too hard to do it consistently,
so we merged them.
Kind regards,
/Eugenio

Subject: [Freesurfer] [FSL] Hippocampus subregions question
External Email - Use Caution
Dear FSL members,
First, thanks for your great work about the hippocampus subfield. Second, I
have some question about your subfield/subregions definitions:
1. Can you give me your actual definition of the GC-ML-DG in your last
release (FSL6.0) of the hippocampus segmentation? Is-it possible to speak about
granular cell layer, like used in the Ho, 2017 (Molecular psychiatry) article?
2. Moreover, is-it possible to say for the the hippocampal tail that it is
comprised of portions of CA and dentate gyrus?
3. For molecular layer (ML), is it the ML of the CA subiculum sub volumes or
the ML of the DG or both?
Thank you in advance,
--
