Stanford researchers working in collaboration with the BrainGate consortium have created a new—and much better—brain-computer interface that enables people with paralysis to type using a point-and-click system.
The interface requires that two small electrode arrays be placed in the brain to interpret signals from the brain’s motor cortex. The user then imagines their finger and hand movements to guide the cursor on screen. As one of the researchers noted, this is a step toward developing “powerful, intuitive flexible neural interfaces that we all hope will one day restore communication, mobility, and independence for people with neurologic disease or injury.”
