Complete Guide to Brain-Computer Interfaces (BCIs): How They Work, Applications, Challenges, and Ethics
Brain-computer interfaces (BCIs) are reshaping how people interact with technology by translating neural activity into actionable commands. These systems span a spectrum from non-invasive headsets to surgically implanted arrays, and they’re gaining traction across healthcare, accessibility, entertainment, and research. How BCIs workBCIs capture brain signals—electrical, magnetic, or metabolic—and convert them into digital information. Non-invasive approaches […]
