\nThe call is coming from inside the body\nThe idea that hundreds of species of bacteria are nestled comfortably in our intestines used to be surprising. But the gut microbiome is experiencing a kind of media heyday as people realize that its function is critical to not just how we digest our food, but also to our overall health. A little more than a decade ago, researchers showed that tinkering with rodents’ gut microbiomes affected the animals’ social and cognitive behaviors.
