For the first time ever, a neural device has been used to restore locomotion in paralyzed primates. It may be years before clinical trials can begin for humans, but this latest breakthrough marks an important step in that direction.

A new study published in the science journal Nature describes a new neuroprosthetic interface that acts as a wireless bridge between the brain and the spine, bypassing the injury. Called the “brain-spine interface,” the system restored movement in the paralyzed right legs of two rhesus monkeys. The system was developed by neuroscientist Grégoire Courtine and his colleagues at the Swiss Federal Institute of Technology in Lausanne, along with help from researchers at the University of Bordeaux, Motac Neuroscience, and the Lausanne University Hospital (CHUV).
