Surface-based searchlight approach

Read this paper "A comparison of volume-based and surface-based multi-voxel pattern analysis", talking about the effect when using the voxels connected in the geodesic surface of the cortex rather than connected in volume. I think this approach would make the estimated parameters more accurate.
