Story summary
- Researchers in Germany froze living brain tissue to temperatures below –150°C, halting all biological activity.
- Upon warming, the neurons regained electrical signals, indicating functional recovery.
- The study, led by Alexander German, focused on the hippocampus, a region crucial for memory.
- Electron microscopy showed preserved synaptic structures, suggesting tissue connectivity remained intact.
- Future research will explore frozen tissue viability and its ability to support complex brain functions.
