Tiny VR Goggles for Mice

Scientists made very small VR goggles for mice. These goggles help them study how mice act in virtual worlds. The goggles use parts from smartwatches. In one test, mice saw a dark spot coming at them. This made the mice jump, thinking it was real. The scientists hope this will help them learn about how the brain works. It may also help them understand diseases like Alzheimer's better.

The team at Cornell University made these goggles. They are much better than the big screens they used before. The mice react more naturally with the goggles. This new tool could help scientists learn a lot about how animals think and move.
