👑Brain-computer interface technology

A brain-computer interface is a direct connection channel established between a human or animal brain and an external device. The one-way BCI technology lets computers receive incoming commands or send signals to the brain, but not simultaneously send and receive signals; the two-way BCI allows bidirectional information exchange between the brain and external devices.

Brain-computer interface signals come from the central nervous system and are independent of the peripheral nervous and muscular system in transmission. It is often used to assist, enhance and repair the sensorimotor function of the human body or improve the human-computer interaction ability.
