The only fundamental difficulty I can see with this is if the brain
actually uses quantum computation, as suggested by some evidence that
photopsynthesis does (quoted by Bruno in another thread) - in which
case it might be impossible, even in principle, to reproduce the
activity of the rest of the brain (I'm not sure whether it would, but
it seems a lot more likely).
