Deep-frozen brain region restarts electrical activity after thawing

Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and Uniklinikum Erlangen have succeeded in preserving brain tissue through extreme deep freezing. After thawing, the neurons begin exchanging electrical signals again. The procedure could be used, for example, to preserve brain tissue removed during surgery so that it can be examined later. This could also facilitate the development of drugs. The research findings have been published in the journal Proceedings of the National Academy of Sciences.
