In a Breakthrough, Cornell Scientists Develop Realistic VR for Mice
In a cutting-edge development, scientists at Cornell University have introduced an innovative technology that allows mice to experience virtual reality (VR) more realistically—and frighteningly—than ever before in a laboratory setting. Dubbed MouseGoggles, this pioneering technology has the potential to revolutionize animal studies involving VR.
Cornell researchers, led by fig3>Issacson, have taken a unique approach to VR for mice. Instead of attempting to create a mini-Oculus Rift from scratch, they’ve devised a system using affordable, off-the-shelf components borrowed from smartwatches and other existing devices. Mice wearing MouseGoggles are placed on a treadmill, their heads secured to the device while receiving visual stimuli.
To validate their system, scientists exposed mice to various stimuli, tracking brain activity and observing their behavior. Through a series of tests, researchers found that mice responded as expected to the VR, seeing and reacting to virtual stimuli. In one instance, mice reacted to approaching dark blots, which could represent potential predator threats.
The team’s findings were published earlier this month in the journal Nature Methods. The development of more realistic VR for mice could offer numerous benefits in the future, according to the researchers. Accurate VR experiments could help scientists better map and understand the brain activity of mice modeled with conditions like Alzheimer’s, particularly in areas related to spatial navigation and memory. It could also enhance fundamental research studies examining potential therapies for brain disorders.
The Cornell team isn’t the first to create a VR system for mice, but they claim their MouseGoggles is the first to include eye and pupil tracking. Moreover, they’ve developed a lightweight, portable VR setup that could be used with larger animals like rats or squirrel monkeys. Looking ahead, they aim to incorporate more sensory stimulations, such as smell and touch, in future iterations.
