Brain implants deliver new sensations

February 19, 2013News

I might have to move up some of the dates in my upcoming novel, The Boost. It takes place in a world in which most of us carry cognitive implants. Now, with the latest news from Duke researcher, Miguel Nicolelis, I think that day may come earlier than my projected 2043. Nicolelis and his team have hooked up rats to infrared sensors, and linked them to the part of their brain that governs touch. This light is invisible to mammmels. But when it went on, the rats immediately started touching their whiskers. They felt the light as touch. (Here's the BBC report.)

The early  uses for this technology will be to help people with disabilities. Conceivably, a blind person could regain sight, or some version of it, through another sense. Already, people are moving prosthetic limbs with their thoughts. But in the longer run, as I see it, advances in brain-machine technology will extend to the population at large. Imagine downloading an app where you "feel" infrared light or police radar. You might not want it on all the time. But it would have its uses.

Nicolelis has a bigger announcement coming up next month. The Telegraph speculates that he and his team may have pioneered communication between two brains. We'll see. But if that type of communication isn't coming soon, it's coming later. Eventually, I'm betting, we'll all be facing the question of whether to wire our brains--or to stay back in the cognitive slow lane. 

This is a look at one of the experiments. You can make more sense of it if you read on Nicolelis' blog and look at the other videos.
