brain transplant

A brain transplant involves replacing a person's brain with another brain from a donor. While technically complex and currently not feasible with existing technology, it would require disconnecting and reconnecting the brain's nerves and blood vessels to the recipient's body. The main challenges include preventing organ rejection, ensuring the brain's survival, and establishing functional connections with the body’s nervous system. As of now, brain transplants are theoretical and raise numerous medical, ethical, and technical questions. Instead, researchers focus on understanding brain injuries and developing treatments to repair or protect brain function.
