Dear Freesurfer Developers,

I have some questions regarding hippocampal and amygdalar subregional 
segmentation in the latest Freesurfer version:


1) Can one use the segmentation outputs as ROI masks, register those to native 
space functional image, and extract functional time courses in order to perform 
seed-based subregional functional connectivity analyses?



2) How sensible do you deem it to assess the functional connectivity profiles 
of all the subregions? Would you argue against grouping some of the subregions 
into a larger subregion and assess connectional profiles. For instance 
combining CA 1 to 4 into a CA subgroup? Or the Subiculum and Pre- Parasubiculum 
into one subgroup? I am asking this because most literature on hippocampal 
subregional connections focuses on the major subregions (CA, Dentate Gyrus, 
Subiculum), with very limited knowledge on connectivity profiles of smaller 
individual subregions.



3) Is it already possible to segment the amygdala subregions as well with this 
new pipeline? On the Freesurfer website the following is stated: “In addition 
to the hippocampal subregions, it also simultaneously segments the nuclei of 
the amygdala”. However, the page also states that this functionality will soon 
be available in the dev version, so I am not sure whether the amygdala 
subregional segmentation pipeline is already in place? If not, is there a 
preliminary release date known already?


Thanks for your time and effort!
