Researchers from the University of Nottingham in the U.K. transformed a person's electrical brain activity into a unique, colorful light display with the help of a magnetoencephalography (MEG) scanner, according to a report published July 12 by Business Insider.
The scanner is an alternative to traditional MRI that can be worn like a helmet, allowing patients to move without constraint.
When worn, the headset records electrical activity in the brain though the method of electroencephalography (EEG) and sends the signals to a light ring in the shape of a human brain to identify which regions are active or inactive.
"The display is shaped like a human brain to represent which parts are in use when the headset is worn," according to the article, which explained that the lights turn blue when brain activity is increased and turn red when activity is lacking.
