Ben:As an example, no one yet knows how the brain represents 3D shapes ... is it a literal 3D map of an object? some kind of symbolic representation? some combination? something inbetween
Bob:Yes, there does seem to be an increasing amount of evidence that the
brain uses some form of 3D grid based representation of space. Place cells in navigating creatures have been known about for a long time.
What are the implications for computing - how would it have to change - if the brain uses literal 3D maps - and they turn out to be a necessity? [Computers, I take it, can't currently produce them?]
