I'm assuming that you don't need to model e.g. quantum gravity effects to faithfully simulate a brain. Probably chemistry is enough *shrug. Some people think that consciousness is related to quantum mechanics, but the laws of quantum mechanics can be simulated with a Turing machine so that doesn't necessarily change the story.
