Scientists Just Woke Up A Frozen Brain

In a German laboratory scientists just pulled off something that sounds like it belongs in a science fiction story: they froze living brain tissue to temperatures colder than the harshest Antarctic winter, kept it there for a full week, and then watched electrical activity return when it was carefully warmed back up. The research, led by Alexander German at Friedrich-Alexander University Erlangen-Nuremberg and published in the Proceedings of the National Academy of Sciences, used thin slices of mouse hippocampus, the brain region most closely tied to memory and learning. The key to making it work was a technique called vitrification, which prevents the water inside cells from forming ice crystals that would normally tear delicate cell membranes apart. Instead, a carefully balanced mixture of protective chemicals allowed the tissue to solidify into a smooth, glasslike state at temperatures as low as negative 196 degrees Celsius, with the samples then stored for seven days at negative 150 degrees.

When researchers slowly and carefully warmed the tissue back up, something remarkable happened: spontaneous electrical signals returned, with neurons firing and communicating across their connections much as they had before the freeze began. The physical structure of the synaptic connections, the microscopic bridges that carry signals between brain cells, remained largely intact throughout the entire process. Previous attempts to freeze brain tissue had managed to preserve the physical shape of cells but not their ability to actually communicate and function, making this recovery of genuine electrical activity a genuine first. While the experiment involved only small slices of mouse brain tissue and a full working brain is an entirely different challenge, researchers say the findings open the door to new possibilities in medicine, from preserving donor tissue for transplant research to, one day, exploring longer forms of suspended biological states.
