⚠️ Scientists just revived activity in frozen mouse brains

Researchers have achieved something long thought impossible: restoring neural activity in brain tissue after deep freezing.

What happened:

• Scientists froze slices of mouse brain using vitrification, a technique that prevents ice crystals from damaging cells.
• The tissue was stored in liquid nitrogen at 196°C for up to a week.
• After thawing, neurons were still alive and began firing signals again.

What they found:

• Brain cells kept their structure and connections intact.
• Neurons showed metabolic activity and functioning mit
