Can the behaviour of the neurons including the electric fields be
simulated? For example, is it possible to model what will happen in
the brain (and what output will ultimately go to the muscles via
peripheral nerves) if a particular sequence of photons hits the
retina? If that is a theoretical impossibility then where exactly is
the non-computable physics, and what evidence do you have that it is
