A wireless implant bypasses spinal-cord injuries in monkeys, enabling them to move their legs.

Doing the same thing with humans will be more complex, says Courtine: the brain decoding is much more complicated. The primate study, for example, used electrical activity recorded from the spinal cord before the injury and “played it back” to restore movement, notes Bouton. “That’s an approach that wouldn’t be practical after an actual spinal-cord injury,” he says.
