(Ecole Polytechnique Fédérale de Lausanne) Non-human primates regain control of their paralyzed leg — as early as six days after spinal cord injury — thanks to a neuroprosthetic interface that acts as a wireless bridge between the brain and spine, bypassing the injury. A feasibility clinical study has begun in Switzerland to test the therapeutic effects of the spine-part of the interface in people with spinal cord injury.
