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.
