Joost, In addition to Donna's pointers, check out: Van Essen, D.C., Dierker, D., Snyder, A., Raichle, M.E., Reiss, A., and Korenberg, J. (2006) Symmetry of cortical folding abnormalities in Williams syndrome revealed by surface-based analyses. J. Neuroscience 26:5470-5483 It shows how significant group differences in sulcal depth can be ascertained despite large regional variability.
