Why Would Only a Person’s Brain Be Cryonically Preserved?

The idea of cryogenically freezing just your brain, known as “neuropreservation” or “neurosuspension,” is based on the idea that the brain is the key to a person’s identity and consciousness. Supporters believe that if the brain can be preserved before any damage or degeneration after death, future technology could allow for full reanimation. The brain would then be implanted into a new body — one made with 3D printing or cloning, a donor body, or an artificial/robot body. Someone may choose neuropreservation as it’s less expensive than freezing the whole body, while still maintaining the possibility of reawakening consciousness. As of 2024, the cost for neuropreservation is around $85,000, versus about $227,000 for whole body cryogenics. The science of neuropreservation is still hypothetical, though, with any success likely several decades or more in the future.
