Thank you Michael, I was wondering about a nuisance specific to area analysis. I understand using ICV or brain volume in volumetric analysis, but for area analysis something like "overall pial area" seems more logical to me. That is why I am curious if there is any literature about area (surface) analysis in particular. Am I at the right track at all?
