Study Links Social Media Use to Changes in Brains of Teenagers

From a New York Times story by Ellen Barry headlined “New Study Links Use of Social Media to Changes in the Brains of Teenagers”:

The effect of social media use on children is a fraught area of research, as parents and policymakers try to ascertain the results of a vast experiment already in full swing. Successive studies have added pieces to the puzzle, fleshing out the implications of a nearly constant stream of virtual interactions beginning in childhood.

A new study by neuroscientists at the University of North Carolina tries something new, conducting successive brain scans of middle schoolers between the ages of 12 and 15, a period of especially rapid brain development.
