The University of Nottingham created a light display that is controlled by brain activity. Using a headset we were able to control the light display with our minds. The display is shaped like a human brain to represent which parts are in use when the headset is worn. Business Insider was given the chance to control lights using nothing but the activity of our brains. We wore a headset that uses a method of recording electrical activity in the brain called Electroencephalography (EEG).
