Bringing a whole new meaning to the phrase "wireless mouse," a team of Stanford scientists has implanted wirelessly charging LED lights into the brains of mice. The experiment was undertaken as part of a study of optogenetics, the method of using light to control brain activity. In what sounds like the beginning of a sci-fi movie, Stanford scientists altered neurons in the mice's brains with green algae genes, modifying them so they would be responsive to light.

Once the mice are implanted with LED lights, Stanford scientists can observe which parts of their brain respond to certain activities. Up until now, the LED lights involved in optogenetics had to be tethered to a charger which significantly limited study. This team of Stanford scientists has created a peppercorn-sized device which charges wirelessly when the mouse is placed in an electromagnetic chamber.

The Stanford scientists' study of optogenetics could have a significant impact on the study of neurological issues such as Parkinson's disease or even affect what the world knows about mental health.
