If they do, you could augment your brain to the point where the original was just a tiny part, and you wouldn't even miss it when it eventually dies off.

An important point is that if you noticed a difference not only would
that mean the artificial parts don't support normal consciousness, it
would also mean the artificial parts do not exactly reproduce the
objectively observable behaviour of the natural neurons.
