Hi Jeff
yes, I think this is still our recommendation for thickness, although perhaps David Salat can verify. As far as surface area, you might get Anderson Winkler to send you a preprint of his newly accepted paper on surface area comparisons and how to do them properly. I would have said normalize by the 2/3 root of ICV (maybe David can comment on this as well)
cheers Bruce

Hello, For cortical thickness normalizations, Bruce said not to normalize based on a HBM abstract (http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg06646.html). Is this still the consensus?
For cortical volume, it is pretty standard to normalize to eTIV.
For cortical surface area (jacobian), I couldn't find any information on the wiki. Does anyone have any recommendations?
Thank you, Jeff
