the Gaussian and mean curvature are differential geometric measures and you can find them in any standard textbook (e.g. do Carmo). The folding indices come from one of David Van Essen's papers - sorry, I don't have the reference offhand, but it shouldn't be too hard to find.

Hi,
The output of function "mris_anatomical_stats" contains the following measurements: integrated rectified mean curvature, integrated rectified Gaussian curvature, folding index and intrinsic curvature index. Can someone please give me a brief explanation of what these measurements are or suggest some reading material.
