How Electrical and Calcium Signaling Work as One to Regulate Blood Flow

Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...

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 ...
