One of the co-founders of Elon Musk’s Neuralink Corp. is building a different kind of brain implant.
That device, made by the startup Precision Neuroscience Corp., went in 63-year-old Tim Fisher earlier this month. In an operating room in Philadelphia, a surgeon placed a sliver of film, thinner than a human hair and embedded with over a thousand electrodes, on Fisher’s brain. After a little training, when Fisher moved his left hand, so did a nearby robotic appendage — guided by signals from his brain and the new brain patch. “It was an amazing experience,” said Fisher. A retail worker who lives in West Chester, Pennsylvania, and has Parkinson’s disease, he said he’s drawn to these kinds of implants because his tremors make everyday tasks like typing or opening a jar near-impossible. The brain device that Fisher used was cleared by the US Food and Drug Administration late last month for limited uses, bringing Precision one step closer to a commercially-available technology that one day might allow people to control computers or other devices with just their thoughts.
