BCI (brain-computer interface) systems

A brain-computer interface (BCI) is a technology that enables direct communication between the brain and an external device. It detects electrical signals generated by brain activity, interprets these signals, and translates them into commands to control computers, prosthetics, or other equipment. BCIs are used to assist individuals with disabilities, enhance human capabilities, or explore brain function. They typically involve sensors placed on or in the skull to record neural signals, complex algorithms to decode these signals, and output devices that respond to the user’s thoughts or intentions. Overall, BCIs bridge neural activity and digital systems, facilitating new ways to interact with technology.
