Brain-Computer Interfaces (BCIs): Uses, Risks, and the Future
Brain-computer interfaces (BCIs) are transforming how people interact with technology and the body. By translating neural activity into actionable signals, BCIs enable control of prosthetic limbs, communication for people with severe motor impairments, seizure monitoring, and new forms of human–machine interaction. Progress in materials, signal processing, and miniaturization is moving BCIs from lab demonstrations into […]
