A brain implant manages to decode the speech and movement of paralyzed individuals.

Saying hello while waving… this simple gesture is impossible for many paralyzed people, even when they have a brain-computer interface. This is because these brain implants, which read neural activity, generally only decode one type of information: either the word, or the movement of the body. But a new solution has just been presented by researchers at the University of California, San Francisco: an innovative way to train these devices to allow them to simultaneously decode multiple pieces of information, including speech and arm movements. Their approach, presented on September 14, 2026 in Nature Neuroscience, makes brain implants more functional and promises to give users more autonomy.
