A Neural Bridge. The brain-spine interface developed for this study uses a brain implant like this one to detect spiking activity in the brain’s motor cortex. Seen here, a microelectrode array and a silicon model of a primate’s brain, as well as a pulse generator used to stimulate electrodes implanted on the spinal cord. Credit: Alain Herzog / EPFL
An international team has used a wireless “brain-spinal interface” to bypass spinal cord injuries, SCIs in a pair of rhesus macaques, restoring intentional walking movement to a temporarily paralyzed leg. This is the first time a neural prosthetic has been used to restore walking movement directly to the legs of nonhuman primates...
