Would you normalize for differences in head size by adjusting for eTiV or total surface area? 
Thank you so much,

Thank you so much.
I am still in doubt as to whether adjust/normalize for brain volume or otherwise surface area before comparing groups.
Thank you for your advise,
best wishes,
Elisabetta

Thank you so much,
