Researchers made VR goggles for mice to study how their brains respond to swooping predators

Believe it or not, scientists have been using virtual reality setups to study brain activity in lab mice for years. In the past, this has been done by surrounding the mice with flat displays -- a tactic that has obvious limitations for simulating a realistic environment. Now, in an attempt to create a more immersive experience, a team at Northwestern University actually developed tiny VR goggles that fit over a mouse's face... and most of its body. This has allowed them to simulate overhead thre...
