Brain-Computer Interfaces (BCIs) read brain signals and translate them into commands for machines. This allows paralyzed patients to operate prosthetics, gamers to interact with virtual environments, and scientists to study cognition. BCIs use electrodes, sensors, and advanced AI algorithms to interpret neural activity. While still emerging, BCIs promise transformative applications in medicine, entertainment, and human-computer interaction, offering a new way to communicate and interact with technology.
**Key takeaway:** Think to control machines directly.
