To help people suffering paralysis from injury, stroke or disease, scientists have invented brain-machine interfaces that record electrical signals of neurons in the brain and translate them to movement. Usually, that means the neural signals direct a device, like a robotic arm. Researchers are now bringing brain-machine interfaces to the next level: Instead of signals directing a device, they hope to help paralyzed people move their own limb, just by thinking about it.
