Our Brains and Guts

Is your gut the one running the show?

We think of the brain as the body's control centre. But research shows many of the body's most important functions start with signals from the gut.

Our researchers study our microbiomes and how they influence the communications between our guts and our brains, affecting everything from our health to our mental states to our relationships. Because while our brains are in charge, the bugs in our bodies have a pretty big say, too.
