MeanCurv: integrated absolute value of the mean curvature GausCurv: integrated absolute value of the Gaussian curvature FoldInd and CurvInd are two indices that David Van Essen defined in a paper of his that we also compute:
FoldInd: integral over surface (Kmax * (Kmax-Kmin))
you can check out the Drury and Van Essen paper for the complete definitions.

Dear All, We are interested in degree of cortical folding within our subject populations. Would someone please help me to better understand what the measures "MeanCurv", "GausCurv", "FoldInd" and "CurvInd" in the ?h.aparc.stats files mean? Also, are whole brain stats reported elsewhere? Thanks, Sasha
