Synthetic sense of touch. The cyber human can not be far off . A team from Duke fitted the animals with an infrared detector wired to electrodes implanted in the part of the mammalian brain that processes information related to the sense of touch. One of the main flaws of current human, brain-controlled prosthetics is that patients cannot sense the texture of what they touch. The goal is to give quadriplegics not only the ability to move their limbs again, but also to sense the texture of objects placed in their hands or experience the nuances of the terrain under their feet. The lab studies how to connect brain cells with external electrodes for brain-machine interfaces and neural prosthetics in human patients and non-human primates, giving them the ability to control limbs, both real and virtual, using only their minds. The team have shown that monkeys, without moving any part of their real bodies, could use their electrical brain activity to guide the virtual hands of an avatar to touch virtual objects and recognize their simulated textures.
