How your gut affects your mental health

In a lab in Ireland, a group of scientists stand around a stainless steel table. One of them is holding a device, not unlike a small turkey baster. His free hand plunges into a box on the table and retrieves a mouse.

Using his device, he administers the brown solution within…rectally.

This unfortunate soul has just received a fecal microbiota transplant. The donor was not another mouse but a human being. And the person in question had symptoms of severe depression.

Jonathan speaks to John Cryan, author of the study that showed a relationship between gut and brain. In this episode, we learn more about his fascinating research, how microbes may affect our brain, and to eat to appease your gut bugs.

• John Cryan is a professor at University College Cork and a world-leading researcher into the relationship between our brain and our gut microbiome.
