Scientists have been using virtual reality setups to study brain activity in lab mice for years. Previously, they surrounded the mice with flat displays, which had limitations in simulating a realistic environment. However, a team at Northwestern University has developed tiny VR goggles that fit over a mouse’s face and body, creating a more immersive experience. This allows them to simulate overhead threats and map the mice’s brain activity.
The system, called Miniature Rodent Stereo Illumination VR (iMRSIV), is not strapped onto the mouse’s head like a VR headset for humans. Instead, the goggles are positioned at the front of a treadmill, surrounding the mouse’s entire field of view as it runs in place. John Issa, the study’s co-first author, explained, “We designed and built a custom holder for the goggles.” The optical display covers…
