Researchers from Cornell University unveil MouseGoggles, an immersive virtual reality headset for mice that was made using low-cost, off-the-shelf components, such as smartwatch displays and tiny lenses. It offers visual stimulation over a wide field of view while tracking the mouse’s eye movements and changes in pupil size.
The team hopes that this technology will help unlock neural activity that informs spatial navigation and memory function, thus providing new insights into disorders such as Alzheimer’s disease as well as its potential treatments. How does it stay on a mouse? Well, they aren’t exactly wearing the headset, as the mouse stands on a treadmill with its head fixed in place. It then peers into a pair of eye pieces, allowing the mouse’s neural activity patterns to be fluorescently imaged.

It’s a rare opportunity, when building tools, that you can make something that is experimentally much more powerful than current technology, and that is also simpler and cheaper to build. It’s bringing more experimental power to neuroscience, and it’s a much more accessible version of the technology, so it could be used by a lot more labs,” said Matthew Isaacson, the study’s lead author.
