MouseGoggles bring the immersive world of virtual reality to rodents
While it might sound like a cute gift to buy for your pet mouse, a new set of virtual reality goggles have a much more serious purpose. The inventors say they should help advance research into Alzheimer's disease and other brain conditions.
“It definitely benefited from the hacker ethos of taking parts that are built for something else and then applying it to some new context,” said study co-author Matthew Isaacson, who has previously made display systems for fruit flies. When the team submitted their study along with the build specs of the googles to the journal, Nature Methods for publication, an anonymous reviewer suggested also adding a small set of cameras in each eyepiece so that the animals' pupils could be tracked, which they did. Indeed, the researchers were able to observe activity in the primary visual cortex, which confirmed that the goggles were properly transmitting sharp images to the rodents' retinas.
