Hi all, I would need some information about the local gyrification index. I run the analyses and found which are the average indices for subject and hemisphere.
1. Is there a method to perform vertex-wise group statistics? that is may I compare maps of gyrification across groups? 2. Is there a method to obtain average gyrification for a single label of the atlas? For example gyrification of superior frontal gyrus. I understand that sulci are often used to find the delimitation of a gyrus or a brain area, and probably this is a problem. 3. Are there any other method to measure the presence or the depth of a sulcus. We are analysing a group of subjects with a genetic illness. They often lack a sulcus in the orbitofrontal area. Is there a method to quantify this using freesurfer? thank you for your help best wishes Angela _______________________________________________ Freesurfer mailing list [email protected] https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.
