Working with researchers at Kinki University, Ohta implanted the special semiconductor camera inside the hippocampus of the mouse's brain, designing the devise so that a screen showed blue light whenever the camera captured memory being recorded by the brain.

The researchers injected the mouse with a substance that lights up whenever there is brain activity. The camera then captures that light and the visuals come up on a screen.
