If you're referring to VERTEX-WISE analyses of area and volume, there are "issues" with the interpretability of those measures.
Don Hagler has posted on this several times. For example, most recently see: http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg15205.html

Hi,
I am wondering what is going on "under the hood" when one makes a choice under the Design tab in the Measure (Dependant Variable) box for Measure. For example if one chooses "Volume" instead of Thickness, what exactly is being used as volume? Where does the information on volume come from? I am hoping the answer will be the volume associated with each vertex, but where is this information?
Thanks....J
