Researchers from Brown University have developed a way to view the brain using two dimensional neural maps. With their software, you can navigate the brain the same way you would use a Google Street Map.
The benefit to all this being that you can easily spot bundles of neurons (or whatever you're looking for) without the interference from all that other crap one stores up there. For instance, a doctor could inspect a specific group of fibre tracts by using their mouse to select that bundle of neurons. On top of improved visibility, they're also able to see extra info, statistics and a 3D view of just that section. But I wonder what a Street View component would entail - Magic School Bus, anyone?
