A study by researchers from Dartmouth University has shown that friends have more similar brain responses to video clips when compared with brain responses of friends-of-friends and more distant people. This astonishing result suggests that friends process information from the world around them in rather similar ways, even to such an extent that brain reactivity should be able to predict who are likely to engage in friendship.
