FOR the first time, scientists have successfully managed to cryogenically freeze a brain and then revive it. Scientists have successfully cryogenicaly frozen a brain In a step towards eternal life, researchers from 21st Century Medicine (21CM) managed to freeze the brain of a rabbit using a technique known as Aldehyde-stabilized cryopreservation (ASC). The team, led by recent Massachusetts Institute of Technology graduate Robert McIntyre, wrote in a press release: "Using a combination of ultrafast chemical fixation and cryogenic storage, it is the first demonstration that near perfect, long-term structural preservation of an intact mammalian brain is achievable.” Scientists preserved a rabbit brain They achieved this by filling the vascular system of the brain with chemicals that are designed to halt the decaying process, and then froze it to -135 degrees celsius. When the brain was warmed, the scientists found that the majority of its cell membranes, synapses and structures were still in tact and ready to function. A statement read: “The key breakthrough was the quick perfusion of a deadly chemical fixative (glutaraldehyde) through the brain’s vascular system, rapidly stopping metabolic decay and fixing proteins in place by covalent crosslinks.” Kenneth Hayworth, the Brain Preservation Foundation president, said: "Every neuron and synapse looks beautifully preserved across the entire brain. “Simply amazing given that I held in my hand this very same brain when it was vitrified glassy solid... This is not your father's cryonics.” The Brain Foundation Preservation said of the next step: “Focus now shifts to the final Large Mammal phase of the contest which requires an intact pig brain to be preserved with similar fidelity in a manner that could be directly adapted to terminal patients in a hospital setting.” The end goal, according to the report published in Cryobiology, is to create a freezing process which doesn’t dehydrate the brain, which would be suitable for human use in the future.

Has the rabbit been able to confirm this?
