Wireless technology to alter behavior, model diseases, and deliver drugs to the brain

We already have technology to alter one’s behavior. It’s called television.

FYI: Is mind control the future for TVs? , Manipulating morals: scientists target drugs that improve behaviour and Are U.S. government microwave mind-control tests causing TV presenters’ brains to melt down?

Optogenetics is a method of using light to control cells in the brain. It can be used to alter behavior, model diseases, and maybe even one day, deliver drugs right where you need them. And now, it’s wireless! With lasers!

 

With genetic engineering, we can design cells that respond to light (from lasers or LEDs) by activating or deactivating themselves or otherwise changing their functionality. The appeal of using light to alter cells is that we can turn light on and off at the speed of, you know, light, which allows us to keep up with the speeds at which things happen inside our cells. For example, neurons in the brain send signals to other neurons using electric spikes that occur in just a few milliseconds, but with lasers, it’s possible to very precisely control (or disrupt) these messages, and this is what optogenetics is all about.

So what can optogenetics do for you? Well, in one example, researchers have found that they can use optogenetics to be able to drive neurons responsible for creating dopamine, and mice who had brain lasers (BRAIN LASERS!) tuned to stimulate those neurons started to act like they were on happy drugs. The same sort of technique has also been used to control awakeness in mice with narcolepsy….

As with every technology, wireless is obviously the way to go, and a company called Kendall Research has come up with a completely wireless optogenetic device that weighs only three grams. It’s designed to be plugged into the brain of a mouse and function like a wireless router, taking signals from a computer and routing them to the laser and thence into the mouse neurons. This system doesn’t just communicate wirelessly, it’s also powered wirelessly, using an array of supercapacitors to transmit bursts of power when necessary.
