Using the flexible implant, the Swiss scientists reported today in the journal Science that they could overcome spinal injury in rats by wrapping it around the spinal cord and sending electrical signals to make the rodent’s hind legs move. They also pumped in chemicals to enhance the process. After two months, they saw few signs of tissue damage compared to conventional electrodes, which ended up causing an immune reaction and impairing the animal’s ability to move.
