- Researchers made a new tool that uses light.
- It measures activity inside living brain cells.
- The tool makes light inside the cells themselves.
- The light comes from a small chemical reaction.
- No bright external light is needed for recording.
- This reduces damage to the cells during study.
- The tool can see single cells and tiny parts.
- It works in animals such as mice and fish.
- Scientists can record brain activity for many hours.
- This method helps researchers understand brain function better.
