This could be a huge value-add to the groups that have invested heavily in human-directed knowledge graph construction (e.g. Project Halo/Aristo at the Allen Institute for AI).
Agree 100%. It doesn't even have to be connectivity (brain wiring). There have been plenty of studies that have found a variety of different neuropathologies at the cellular scale.
I recommend moving to openlayers 3 (http://openlayers.org) - it's not backward compatible with OL2, but the improvement in user interaction and tile display is worth it, especially on mobile targets.
