Hi Ignacio,
I see. You could do that, but I don't think it will show what you want. There is a big geometric component to the thickness - crowns are thick and fund are thin - so at the very least you might try including mean curvature as a covariate.

Ok, Let's say I do know the mean cortical thickness value of a subject. Then is it possible know what brain areas differ more from that mean value by using a color map visualization (I.e. for example: red = higher deviations, deep blue = lower deviations)? So this way I can determine where there may exist some kind of dysplasia.
Best regards.

Best regards. 2011/7/1 Bruce Fischl <fischl@nmr.mgh.harvard.edu> Hi Ignacio you mean different from the median in that subject? Easy enough to do in matlab, but we don't have anything out of the box to do it cheers Bruce On Fri, 1 Jul 2011, Ignacio Letelier wrote: Hi forum Is it possible to get statistical maps of cortical thickness differences in the same subject?
