All you have to do is not smooth your data in the volume, not average it across subjects in the volume, and map data from individual volumes to individual surfaces. Then you can average across subjects on the surface using a folding-based surface registration. Just doing these things dramatically improves your ability to know where you are in the cerebral cortex.
