I think it very likely that the brain can be so modeled.  But the meaning

up to the brain.  Its computations have no canonical interpretation in
themselves.
You can connect the simulated brain to transducers which convert
environmental inputs into electrical signals. But then, what would
happen if the same electrical signals were input from data on disk
rather than the environment? Would the brain's experience be
different? If so, how would it know where the data was coming from?

It wouldn't know; and it's responses would have no meaning except to someone who did know. Context is essential. Otherwise you get the rock that calculates everything.
