Brain-computer interfaces read patterns in brain activity and translate them into commands for a device.
- Sensors collect brain signals either outside the head or through an implant.
- Software interprets patterns tied to intended movement or communication.
- A computer, prosthetic, or wheelchair carries out the command.
- Researchers must address safety, privacy, consent, and long-term support.
Good to know: Early implants are offering medical hope for some paralyzed patients while raising important ethical questions.
