Researchers at Howard Hughes Medical Institute tested whether rats, like humans, can use their thoughts to navigate a virtual environment.

They implanted a brain-machine interface in rats to record their hippocampal activity.

After having the rats navigate an on-screen virtual environment while running on a spherical treadmill, the researchers had them navigate the virtual reality (VR) arena using only their thoughts.

The brain-machine interface translated the rats' neural activity into on-screen motion, and they were rewarded when they recreated the hippocampal activity associated with a specific location.
