STATES CHRONICLE – According to the latest news, scientists restored the brain of a cryonically frozen rabbit.
A group of researchers have recently announced they managed to bring back to life a rabbit in cryogenic state. This is the first time when a mammal was restored in nearly perfect condition. Using a method called Aldehyde-stabilized cryopreservation scientists froze a rabbit at -211 degrees Fahrenheit.
Experts claimed this technique is able to protect the brain’s structures associated with learning and memory. Cryonics is known to enable the low-temperature preservation of animals and humans. Usually, cryoprotectants are used to prevent ice formation during cryopreservation.
The procedure aims to heal those who cannot be saved with modern medicine later when it might be possible. The process enables long-term memory, personality, and identity to be preserved in durable cell formations and patterns in the brain.
If they can be preserved and accessed later, it means someone could actually ‘time travel’ into the future in their brain. Cryopreservation of people or massive animals does not interfere with current technology. However, scientists are still working on this matter.
Kenneth Hayworth, neuroscientist, said
‘This result directly answers a main skeptical and scientific criticism against cryonics—that it does not provably preserve the delicate synaptic circuitry of the brain”.
Using this technique, experts replaced the rabbit’s blood with a chemical fixative, known as glutaraldehyde .This process prevented metabolic decay and fixed the proteins in place. The method stabilized the tissue and prevented the brain from shrinkage and other damages.
The animal’s brain was filled with an increased concentration of cryoprotectants which solidified it and stored it at -211 degrees Fahreinfeit. The brain was afterwards rewarmed and the cryoprotectant chemicals removed. Moreover, experts used electron microscopes to see if the rabbit brain’s neural circuits were properly stored and undamaged when thawed.
Scientists interested in cryonics have been trying to find a way of enabling medical ‘time travel’. Such process permits the body of a patient to stop ageing and decaying.
Experts think they are ready to attempt to prove the technique is able to store larger brains, such as a pig’s. Eventually, they might try this on humans as well. The fact that scientists restored the brain of a cryonically frozen rabbit is considered to be an innovative step into this field which raised worldwide interest.
