Tiny camera implanted in mouse’s brain

Japanese researchers have implanted a small camera inside a mouse's brain to monitor brain activities and to know about memory formation, in an experiment. It is hoped that some day it can be applied on humans to treat illnesses such as Parkinson's disease.

The research was conducted at Nara Institute of Science and Technology in western Japan. Professor Jun Ohta, along with researchers at Kinky University, used a camera with dimensions 3mm long, 2.3mm wide and 2.4 mm deep. The camera was put inside the hippocampus of the mouse's brain. It is designed in such a way so that a screen flashes blue light whenever the camera captures memory being recorded by the brain.

A substance was injected into the mouse’s body that lights up whenever there is brain activity. The camera then captures that light and the visuals appear on a screen.

According to Ohta, it would take a very cautious approach and at least 10 more years for such micro cameras to be implanted in human brains.

So watch out! Who knows, if such a camera is put inside your brain, it may tell a lot about you that you wouldn’t reveal otherwise!
