While this may be the oldest brain in Britain, (at 300 BC) it's not the world's oldest by a long shot. The oldest intact brains in the world come from paleo-indian skulls found in an anoxic sinkhole in Florida. Discovered by freshwater divers, archeologists were shocked to find soft brain tissue almost 9000 years old within some of the skulls. These unique brains had shrunk to half their normal size, but were otherwise intact, with easily recognizable neurons and clone-able DNA. Some brain tissue also survives in approx 30% of the crania of the Chinchurro mummies (dating from 1800BCE-5000BCE).
