BCIs (brain-computer interfaces)

Brain-computer interfaces (BCIs) are systems that allow direct communication between the brain and external devices. They work by detecting brain signals, often through electrodes placed on the scalp or implanted in the brain, and translating these signals into commands that can control computers, prosthetic limbs, or other technologies. BCIs have applications in medical fields, helping people with disabilities to regain control of movement or communication, and in research to understand brain function. Overall, BCIs represent a bridge between human thought and digital technology, enhancing capabilities and improving quality of life.
