DARPA is determined to develop brain-machine interface technology capable of safely and reliably recording enough information from neurons to control “high-performance prosthetic limbs” that will help amputees or people with paralysis regain lost movement. A new implantable device invented by researchers at the University of Melbourne in Australia could be a big step in that direction.
The procedure for implanting the “stentrode,” a stent-like device containing an array of electrodes, builds on established surgical techniques that use blood vessels as portals for accessing different areas of the body. Unlike traditional approachesto putting recording devices in the brain, it doesn’t require opening the skull and bypasses the risks associated with such an invasive procedure.
