Wireless Implants Allow Optogenetic Control of Animal Behavior Without a Tether (VIDE
Wireless Implants Allow Optogenetic Control of Animal Behavior Without a Tether (VIDEO)
  Optogenetics, the ability to use light to trigger specific neurons thanks to a bit of genetic modification, has appeared as a promising new tool for studying the nervous system and may serve*as a platform for creating therapeutic devices to address various conditions. A major problem with this tech**logy is being able to deliver light into the body*of a live Animal Without tethering it with fiberoptics or implanting large battery powered devices.At Stanford researchers created a device weighing only 20 milligrams and taking up 10 mm3 in volume that can be implanted and then wirelessly powered to emit a blue light on command. This allows the Animal to be free to move about and **t carry a heavy load that can make experiments difficult to perform. The Implants are powered by a microwave chamber with a **vel metal lid that has holes smaller than the frequency of the microwaves being produced. This shields the Animal from the radiation, making it safe to be on top of the unit. But, when the body of the Animal makes contact with the top plate, some energy leaks through, but only e**ugh to power the tiny blue LED. The Animal is **t irradiated and there’s ** significant heating produced around the implant. The researchers tested three different Implants on*the brain, spinal cord, and peripheral nerves of lab mice with great success, paving the way for considerably easier use of optogenetics in research and for various applications we can only imagine.
