In episode 87 Jo welcomes back Dr Emma Yhnell, a neuroscientist and senior lecturer at Cardiff University. Emma is myth busting neuroscience and biomedical topics, and talks about exam stress, trusting experts and the size of our brains.

Jo also learns about an item that's found in the collection of the Royal College of Physicians Museum in London, with a label that doesn't quite tell the whole story.

Presented, produced & edited by Jo Durrant.
