On the Same Wavelength: New Study Illustrates How Similar Neural Responses Predict Friendship

Parkinson et al show evidence for neural homophily -- neural responses when viewing audiovisual movies are exceptionally similar among friends, and that similarity decreases with increasing distance in a real-world social network. Image credit: Parkinson et al, doi: 10.1038/s41467-017-02722-7.

According to a study published in the January 30 issue of the journal Nature Communications, we are exceptionally similar to our friends in how we perceive and respond to the world around us, and these similarities can be used to predict who our friends are. Parkinson et al show evidence for neural homophily — neural responses when viewing audiovisual movies are exceptionally similar among friends, and that similarity decreases with increasing...

This illustration shows a glowing stream of material from a star, disrupted as it was being devoured by a supermassive black hole. When a star passes within a certain distance of a black hole -- close enough to be swallowed up -- the stellar material gets stretched and compressed as it is pulled in. A black hole’s destruction of a star, called ‘stellar tidal disruption,’ releases an enormous amount of energy, brightening the surroundings in an event called a flare.
