Brain revived: Scientists froze brain tissue to −196°C and it started working again |
German researchers at Friedrich-Alexander-Universitat Erlangen-Nurnberg and University Hospital Erlangen have shown that adult mouse hippocampal tissue can be cryopreserved using vitrification, cooled to liquid nitrogen temperature, and later rewarmed with key functions intact. In the study, the tissue regained electrical activity and synaptic communication after thawing. The work marks an important step in cryobiology, but…
