Why do you feel lonely? Neuroscience is starting to find answers

A neuroscientist's hunt for loneliness could help us better understand the costs of social isolation. Do people, when they feel lonely, crave social interactions in the same way a hungry person desires food? And if that's the case, could it be detected in the neural circuits of the brain? This has been the question in Kay Tye's mind, even before coronavirus made the subject even more relevant than what it already was. Adam Piore reports on Tye's fascinating research for MIT Technology Review.
