I'd definitely consider a fully emulated human brain another human, because by the premise that's fully emulated, it will also feel desires, and have survival instincts. That'd be another moral debate -similar to slavery-, because there will be people that would emphatize with them, and there will be others that will think they're just "machines".

But that's talk for another topic. On this case, you'd want to emulate only the physical functioning of our brain and body and not our minds.
