Michelle Dickinson: Researchers have worked out why some hate the sound of others chewing - The Sunday Session with Francesca Rudkin

Do you hate the sound of other people eating? Well, scientists have now worked out why!
Misophonia is the hatred of a sound, usually made by another person like their chewing, breathing or scratching their nails down a chalkboard.
It can inspire a strong reaction in someone - and new research out in the Journal of Neuroscience now thinks they know why, thanks to MRI scanning of brains while these sounds are being made.
They found that people with misophonia have stronger connectivity between the part of the brain that processes sounds and the part of the premotor cortex that handles mouth and throat muscle movements.
Nanogirl Michelle Dickinson joined Francesca Rudkin to chew through the research.
