Chris and Xand continue their conversation with Professor Sophie Scott CBE, a leading expert in the neuroscience of laughter from University College London. They explore what sets real laughter apart from fake, how children pick up the habit of laughing, and whether faking a laugh can make you feel better. Plus, they ask Sophie how she first became interested in laughter research.
