A day when people can interact directly with computers using their thoughts could be on the horizon. Several companies, including Elon Musk’s Neuralink, have begun preliminary human trials of brain-computer interfaces - devices that decode the electrical signals in their brain and translate them into digital bits. Neurosurgeon Benjamin Rapaport is a co-founder and chief science officer of Precision Neuroscience, a company working on brain-computer interfaces. He spoke with WSJ’s Danny Lewis about how the technology works and how these implants could improve the lives of hundreds of thousands of people who could gain the ability to independently engage with the digital world.
