Neuro-Modulation 2.0: New Developments in Brain Implants, Super Soldiers and the Treatment of Chronic Disease
We have known for a while that neuromodulation is effective. Cochlear implants, for example, use electricity to modulate the auditory nerve (really the whole auditory system), while deep brain stimulation has proven itself effective at regulating erroneous neuralelectrical activity and mitigating everything from the tremors of Parkinson’s to the terrors of chronic pain. The potential is there. But so are the issues.
As the folks at Extreme Tech recently pointed out:
So far, these implants have been fairly big things — about the size of a deck of cards — which makes their implantation fairly invasive (and thus quite risky). Most state-of-the-art implants also lack precision — the stimulating electrodes are usually placed in roughly the right area, but it’s currently very hard to target a specific nerve fiber (a bundle of nerves). With ElectRx, DARPA wants to miniaturize these neuromodulation implants so that they’re the same size as a nerve fiber. This way they can be implanted with a minimally invasive procedure (through a needle) and attached to specific nerve fibers, for very precise stimulation.What makes all of this so much more interesting is the fact that, unlike all the other systems of the body, which tend to reject implants, the nervous system is incorporative—meaning it’s almost custom-designed to handle these technologies. In other words, the nervous system is like your desktop computer— as long as you have the right cables, you can hook up just about any peripheral device you want.
