Neuroscientist Emily Finn often trawls Reddit for disagreements about television shows, movies, books or podcasts—any narratives that “evoke really different reactions in different people,” she explains.
Finn, who works at Dartmouth College, has focused her career on finding what makes individual brains unique. In 2014 she and her colleagues discovered that scans of people’s brain networks are different enough to function like fingerprints. These findings flip the neuroscientist’s typical approach to studying the brain.
Finn is part of Scientific American’s inaugural class of Young American Scientists.
