Moscow. February 10th. INTERFAX.RU – A team of scientists from the company’s 21st Century Medicine thawed rabbit and pig brain after cryopreservation while maintaining neural connections, writes resource N + 1 with reference to Cryobiology
A team of scientists 21 Century Medicine used a new technique. cryopreservation called “aldehyde-stabilized cryopreservation” “. Its tested on rabbits and pigs to study the methods of work in a small scale and large mammal brain. Using perfusion device researchers pumped into animal brains fixing solution based on glutaraldehyde and ethylene glycol with addition of a cryoprotectant. They then slowly cooled animal brain to -135 degrees Celsius and stored in this state from 48 hours to several weeks.
The result of experience
Once thawed, scientists removed the animal brain and fixing and cryoprotectant solution, they analyzed the state of the brain by means of electron microscopy. It was found that freezing and subsequent thawing does not affect the microstructure of synapses, they remain intact. This applies both rabbit brain. . And pig brain
“We were the first to implement the procedure of saving everything that neurologists associated with learning and memory with the results today, it seems to me possible to maintain long-term memory.” – Said John Smart, a co-founders of the organization brain Preservation Foundation.
The neurons and synapses form the neural network of the brain. Neural connections are responsible for processes such as the production of speech, memory formation or control of body movements. Preservation of neural connections is a critical step to recovery after cryopreservation, as well as for konnektoma Research ( full description of the structure of relationships in the nervous system of the body – IF )
