In a groundbreaking scientific achievement, a paralyzed man has regained the ability to walk with the help of a wireless “digital bridge” that reconnects his brain and spinal cord. Through a brain-computer interface, nerve signals from implants on the man’s brain are decoded by artificial intelligence, which then wirelessly sends instructions to a second implant in his lower back. This allows the severely damaged nerves in his neck to be bridged, stimulating the leg muscles in the right order for walking. While the technology has immense potential for paralyzed individuals, cost and accessibility remain challenges for wider implementation. Nonetheless, this breakthrough holds tremendous implications for people living with paralysis.
