They’ve designed a headband that measures brain activity, revealing how much a person’s brain is syncing up with someone else’s (and thus, how well two people are communicating). Political scientists say that better understanding this phenomenon of “brain coupling” could help make politicians’ interactions more effective, too. The researchers recorded all three people individually telling an unrehearsed story in their native language about something that had previously happened to them and used the headband to measure brain activity. The headband uses infrared (nearly visible, red light) to actually measure the color of the blood in your brain, Ayaz explained. The sensors in the headband by measuring the color of blood in your brain are thus able to measure activity level.
