GENEVA – A new device has allowed two monkeys to regain use of their paralyzed legs by transmitting brain signals wirelessly, bypassing their spinal cord lesions, a study released Wednesday by the journal Nature said. The implantable device, called a neuroprosthetic interface, was developed by an international team led by researchers at the Federal Polytechnic School of Lausanne (EPFL) and may soon be tested as a remedy for paralysis in humans. "For the first time, I can imagine a completely paralyzed patient able to move their legs through this brain-spine interface," Jocelyne Bloch, a neurosurgeon at the Lausanne University Hospital, said in a press release from EPFL. The interface conceived at EPFL is a multicomponent brain-spine connector, which decodes signals from the part of the motor cortex responsible for leg movements. It then relays those signals in real time to the lumbar region of the spinal cord that activates leg muscles to walk.
