Monkeys with spinal cord damage that paralyzed one leg quickly regained the ability to walk with a wireless connection from the brain to the spinal cord below the injury, scientists reported Wednesday.
The achievement is yet another advance in the rapidly moving field of technological treatments for spinal cord damage.
In recent years, scientists have achieved brain control of robotic hands in monkeys and humans, helped a paralyzed man regain some use of a hand through a chip implanted in his brain, and used electrical stimulation of nerves to enable paralyzed rats to walk again.
