About neuroprostheses

Arthur Clarke once said that advanced science is indistinguishable from magic. In part, we are lucky to live at a time when this statement can be clearly seen. And if most technologies offer us to modify external attributes (smartphones, tablets, smart gadgets we wear on the body), then neuroprostheses penetrate much deeper into our brain, taking on some of the tasks. In this case, the question arises: "where does personality end and man begins?"





Modern neuroprosthetics

The trend of neuroprostheses has been repeatedly raised by various institutions, primarily the military. Fighting without risking combat units is worth a lot. The gaming industry also pushed neurointerfaces, albeit not invasive ones. But. The medical market offers a much deeper intervention in the work of the brain, with new possibilities for each "patient".





What neuroprostheses are capable of

Neuroprostheses are designed to restore connections between the brain and muscles of a person. Or offer the person a worthy alternative. Consider an example of the famous cyborgs of our time: Nigel Ekland and Hugh Herr . In the first case, we are talking about a person who has lost a limb due to an accident at work. Now, instead of a hand, he uses a cyber-prosthesis, which is practically no different from his native limb. Except for the inability to convey tactile sensations. There is also a feedback problem.





The problem of feedback is what you, dear friend, feel at -20 when you are trying to find small change in your pocket with thick gloves. You feel your hand, you know that it follows your commands without question. But you have no idea if you found the coveted coin or not. Likewise, a cybernetic prosthesis without feedback literally fails to convey tactile sensation. Or rather, I was not able to.





Hugh Herr is a mountaineer who, at 16, lost both legs to frostbite. The injury became a reason not only to create better legs for yourself, but also to give such an opportunity to other people. As the accidental victim of the Boston Marathon terrorist attack, and the military, who can now carry loads of 40-60 kg with the same ease as without load.
