Researchers used an implanted, wireless brain-spine interface to help a disabled man regain his ability to walk. The associated study was released in Nature. The lumbosacral spinal cord, which is found near the base of the spine, receives impulses from the brain that cause an animal to walk. Even though these neurons are generally unharmed in spinal cord lesions, abnormalities in descending pathways stop the brain’s instructions from translating into walking. According to earlier study, standing and walking can be facilitated by activating particular regions of the lumbosacral spinal cord. However, these attempts required wearable motion sensors, and produced unnatural walking control with limited ability to adapt to different terrain and volitional demands.
