Dear Freesurfer users and developers,
Yes, sorry... I should have specified this. I meant the mean curvature ('curv' in qdec). And considering that this index is being calculated by formula: 1/radius - there must be an opposite interpretation (so, not a flattening actually, but folding?)... How come? Speaking about survivals after the correction for multiple comparison it is the parahippocampal area. --- Kind Regards, Alex

Dear Freesurfer Users! Is it wise to interpret the increased curvature index in neurodegenerative disorders as a more expressed atrophy (which
manifests
as a flattening)... I am just doubting because I have never worked
with
curvature analysis previously and its interpretations in different articles look quite controversal... The matter is that in our work the observed increase of the curvature index was found in the majority of the "thinned" areas... Thank you very much beforehand.
