# Seems Familiar (DD-429)

> Researchers place mice and rats in virtual reality setups, typically with the animal on a treadmill or floating ball surrounded by screens that update as it walks. Because the animal stays in place, scientists can record neurons during navigation, learning and decision-making. Newer systems use tiny headsets. The footage shows a mouse in a VR rig.

### Transcript

Did you know, VR testing on animals like rats and mice involves placing them in controlled virtual environments to study their behavior, cognition, and neurological responses. This is achieved by designing VR systems tailored to small animals, such as treadmills or spherical setups that track their movements and adjust the virtual world accordingly. NOW YOU KNOW!
