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.”


使用界面的條件,是要把兩個小電極陣列放置在大腦中,用以解讀大腦運動皮層的信號。 然後,用戶便可通過想像手指和手的移動,控制屏幕上的光標。 正如其中一位研究人員所指,這是邁向腦機介面開發的新一步,他們希望“有一天能有一個強大又靈活直接的神經介面,可以幫助有神經系統疾病或創傷的人恢復溝通、靈活及自主獨立的能力。”
