Decapitated skull over 2,500 years old is the oldest preserved brain in Britain
A preserved brain from Iron Age Yorkshire has puzzled archaeologists over how the soft tissue has survived almost intact.
The skull was studied by Rachel Cubbitt from the York Archaeological Trust. “I peered through the hole at the base of the skull to investigate. To my surprise saw a quantity of bright yellow spongy material. It was unlike anything I had seen before,” Cubitt told Culture 24.

interesting and creepy
The brain really is totally preserved. Amazing, better than cryonics. What natural conditions would allow brain preservation to occur for a period of 2,500 years? Complete absence of bacteria if course. The pH would have to be precise and constant. The brain is mostly fat and fat decays (goes rancid) very rapidly. Three degradation mechanisms would need to be avoided – microbial action, oxidation which breaks down the double bonds in the fat, and “Hydrolytic rancidity”. Hydrolytic rancidity is the reaction of fat with water – keeping water out in a burial would be extremely difficult, there is even water in the original brain.
