Janelia researchers have developed a novel system combining virtual reality and a brain-machine interface to probe the rat’s inner thoughts.

The first video describes the system and the VR system:

At the same time that the rat navigates in the VR system, the BMI system records the rat’s hippocampal activity. The researchers can see which neurons are activated when the rat navigates the arena to reach each goal. These signals provide the basis for a real-time hippocampal BMI, with the brain’s hippocampal activity translated into actions on the screen.
