TFW when you're so excited you get those butterflies in your stomach - or John Caldwellmaybe when you see something icky, you feel ill. On today's show, producer Berly McCoy looks at this relationship between our gut and our brain. Berly talks to host Emily Kwong about how the organs evolved to have a tight connection - connections that go beyond transient feelings of excitement or disgust. In fact, an increasing body of research shows links between the gut and conditions we typically associate mostly with the brain – like anxiety and Parkinson's Disease.

Here's a link to the study about gut bacteria and the brain in some children with Autism Spectrum Disorder.
