PUT IT IN PEOPLE, AND TURN IT ON WHENEVER THEY SEE A PICTURE OF BIG BROTHER: Tiny wireless injectable LED device shines light on mouse brain, generating reward. “Using a miniature electronic device implanted in the brain, scientists have tapped into the internal reward system of mice, prodding neurons to release dopamine, a chemical associated with pleasure.”

I predicted this in the New York Times over a decade ago: “One nanotechnology expert, Glenn H. Reynolds, a law professor at the University of Tennessee, said that someday it might even be used to make tiny robots that would lodge in people’s brains and make them truly love Big Brother.”
