Replacing Your Brain: The Radical Plan to Defeat Aging

What if the key to immortality isn’t a miracle drug, but a new brain?

Jean Hébert, a pioneering researcher recently hired by the US Advanced Projects Agency for Health (ARPA-H), has a bold vision: to replace aging human brains with youthful tissue grown in a lab.

This radical approach to defeating death involves gradually swapping out brain parts, allowing the brain to adapt and preserve identity. Hébert’s work, inspired by brain plasticity and promising initial experiments with mice, has attracted significant attention — and a $110 million endorsement from the US government.

While the concept has faced skepticism, with critics questioning whether transplanted tissue can truly integrate and function in an aged brain, Hébert is undeterred. His new role at ARPA-H provides a platform to push the boundaries of what’s possible in neuroscience. Will this ambitious venture lead to breakthroughs in combating aging, or is it just science fiction waiting to unravel?
