How 'mind-controlled' bionic devices could help quadriplegics walk

The development of “mind-controlled” bionic devices moved another step closer today with the publication of a Nature Biotechnology paper describing how a tiny, 3cm-long stent containing 12 electrodes could one day help people living with spinal cord injury to walk with the power of thought.

The device, called the “stentrode”, is inserted into the jugular vein in the neck and pushed up the vein until it reaches the brain’s motor cortex, which is responsible
