- Scientists study fluid that moves through the brain.
- This fluid helps remove waste from brain cells.
- The flow is very slow and hard to see.
- It is difficult to measure in a living brain.
- Researchers use scans and computer tools.
- They teach computers with videos of dye spreading.
- The computer learns to estimate fluid speed.
- Two different paths carry the fluid away.
- Scientists first made measurements in animals like mice.
- The work may help detect brain disease earlier.
