Mapping the Mouse Brain: A Major Advance in Understanding Brain Connections.

Scientists made a big map of a mouse brain. They used a tiny piece of the brain to see how the cells talk to each other. This map shows how 84,000 brain cells connect.

The map shows millions of connections between the cells. It helps us understand how brains work. Scientists can use this map to learn more about our brains.

Brain cells help us think, feel, and move. They send messages to each other. Scientists want to know how these messages work, and what happens when they don't.

The scientists showed a mouse movies to see which brain cells lit up. Then, they made very thin slices of the brain and took pictures. They used computers to put the pictures together and make a 3D map.

This map can help scientists find ways to treat brain diseases. It is like a first step to understanding how brains work. Other scientists can use this map to do more research.
