700-year-old Brain Found Preserved!

Hope THIS will answer few of our questions albeit being an infant's brain.

"I
t is only the left-hemisphere that survived and not the entire brain, which had also shrunk to about 80% of it's original weight due to the (natural) mummification process. Although it was first discovered in 1998 and preserved all this time in a formalin solution, it was found in the skull of a 13th Century infant that was exhumed at an archaeological dig in north-west France. The body of the 18-month-old child was wrapped in leather and kept in a wooden coffin with a pillow underneath the head.

The presence of acidic clay soil and fresh briny water around the burial site is believed to have contributed towards the excellent preservation of the brain. To a certain degree, even the innate cellular structure had been preserved, so much so that intact neurons and dendrites - branched fibres that extend from the cell body of a neuron - had survived for observation in the 21st Century. It was also possible to identify grey and white matter. Apart from the external burial conditions, the toughness of the neuronal myelin sheath and collagen fibres are said to be the reasons for why the brain tissue had been nicely preserved."
