In November of 2016 Nature reported that the results of experiments in Beijing, in which a wireless brain implant — that stimulates electrodes in the leg by recreating signals recorded from the brain — has enabled monkeys with spinal-cord injuries to walk. “They have demonstrated that the animals can regain …

Recent progress in central and peripheral neural interface technology has resulted in impressive capability demonstrations. These include the use of neural signals to control the reanimation of paralyzed muscles or to control high-dimensional prosthetic limbs, external robots, and even flight simulators. In many of these examples, sensory feedback from the …
