Brain-Computer Interface

A direct communication pathway between the brain and an external device that enables users to control computers, prosthetics, or other systems using neural signals rather than physical movement. BCIs are particularly significant for people with severe motor impairments such as ALS, spinal cord injury, or locked-in syndrome, allowing them to communicate and interact with technology when traditional input methods are impossible. Most BCIs use electroencephalography (EEG) to detect brain activity patterns associated with specific mental tasks like motor imagery.
