[0002] A brain-computer interface is a direct connection path established between the human or animal brain (or a culture of brain cells) and an external device. In the case of a unidirectional brain-computer interface, the computer either receives commands from the brain or sends signals to the brain (such as video reconstruction), but cannot send and receive signals at the same time. A bidirectional brain-computer interface allows two-way information exchange between the brain and external devices. A brain-computer interface device is a device that establishes a direct connection path between a human and an external device and uses brain signals to communicate with the outside world.
