Alexandra Morton-Hayward, forensic anthropologist and doctoral candidate at the University of Oxford, holds the two cerebellar hemispheres of a 200-year-old brain, preserved in formalin. Credit: Graham Poulter, brings together the records of more than 4,000 preserved human brains from over two hundred sources, across six continents . Many of these brains were up to 12,000 years old, and found in records dating back to the mid-17th century.
These shrunken, discolored tissues were found preserved in all manner of individuals: from Egyptian and Korean royalty, through British and Danish monks, to Arctic explorers and victims of war., said: “This record of ancient brains highlights the array of environments in which they can be preserved from the high arctic to arid deserts.”
Over 1,300 of the human brains were the only soft tissues preserved, prompting questions as to why the brain may persist when other organs perish. Interestingly, these brains also represent the oldest in the archive, with several dating to the last Ice Age.
