Why Is "Brain Transplant" Impossible?

Live Science explains that whole-brain transplants are not currently possible because the central nervous system’s complex neural connections cannot be reliably rebuilt.

Past animal and human head-transplant attempts, including work by Robert White and later Sergio Canavero, did not solve the core surgical and biological barriers.

The article says the more realistic path is regenerative medicine, such as stem cell therapy, iPS cells, and brain organoid research, for treating brain injury and disease.

These approaches could be relevant for conditions like Parkinson’s disease, but they are still far from replacing an entire brain.
