Decade-Old Frozen Human Brain Shows Perfect Preservation

What Happened Greg Fahy, chief scientific officer at biotech companies Intervene Immune and 21st Century Medicine, recently completed his analysis of brain tissue samples from his deceased colleague L. Stephen Coles. The samples came from Coles’s brain, which has been stored at the Alcor cryonics facility in Arizona since 2014. Fahy’s findings, published after more than a year of analysis, show the brain tissue is “astonishingly well preserved.” When the frozen samples were slowly rewarmed and rehydrated, the cellular structure “bounced back” with every microscopic detail intact.
