Nitpick: Egan's design is different in principle; it's a self-contained device running a bog-standard neural network that, over a number of years, trains itself on the brain's inputs and outputs. So the actual mechanics of how it operates doesn't necessarily reflect the structure of the biological brain. I found that really fascinating as an idea. Being identical is one thing, but does being arbitrarily close to your behaviour make it you?
