Scientists are claiming a major breakthrough in the field of cryonics after a rabbit brain was frozen and recovered in “near perfect” condition – the first time an entire mammalian brain has been restored successfully. The procedure has brought scientists a step closer to fulfilling the sci-fi goal of living forever by resurrecting the frozen dead or installing the human brain into a robot.

Researchers from 21st Century Medicine (21CM) used a new technique, called Aldehyde-stabilized cryopreservation, which protects brain matter associated with learning and memory. The vascular system of the rabbit brain was filled with chemicals that allowed it to be cooled to negative 211 degrees Fahrenheit (-135 degrees Celsius).

This rapidly stopped metabolic decay and fixed the proteins in place. When the brain was later rewarmed and the cryoprotectant removed, the cell membranes, synapses, and intracellular structures remained intact. READ MORE
