- What Are Brain-Computer Interfaces (BCIs)?
A Brain-Computer Interface (BCI) is a technology that allows direct communication between the brain and an external device. It works by detecting neural activity and translating it into digital signals.
✔ Non-invasive BCIs – Use external sensors (e.g., EEG headsets) to read brain activity
✔ Invasive BCIs – Implant microchips in the brain for more precise control
✔ Hybrid BCIs – Combine both methods for improved accuracy
💡 Example: Neuralink has developed a brain implant that enables paralyzed patients to control devices using their thoughts.
