      That’s a really interesting question, samuel1299! We don’t have the technology at the moment to either make a replica brain, or to transplant someone’s brain into someone else’s body. In theory, I guess it would definitely be possible at some point in time – however, if you did make a new brain for someone, would they be the same person? Our brains are constantly changed by the things that we experience – even something as simple as you having a cup of tea this morning in your home, versus me having a cup of coffee in my home, will mean that our brains have been subjected to different chemicals and environments, and will mean that they develop in different ways. So if you transplanted my brain into your body, would you still be you, or would you be me?
