Brain-Computer Interface Quiz

What is a brain-computer interface (BCI)?

• A device that measures brain activity and displays it on a computer screen.

• A type of computer program that simulates brain activity.

• A surgical procedure that connects the brain to a computer chip.

• A technology that allows direct communication between the brain and an external device.

How does a brain-computer interface work?

• A brain-computer interface works by directly connecting the brain to a computer through wires.

• A brain-computer interface works by stimulating the brain to produce desired responses.

• A brain-computer interface works by reading the user's thoughts and interpreting them into commands.
