Misophonia: Why some people are averse to chewing, tapping, and other sounds

  • Previous studies investigating misophonia have shown connections between the auditory cortex and orofacial motor control areas in the brain in people with sound aversion.
  • In a new study, scientists used MRI scans to replicate previous misophonia research on chewing to see what happens in the brain with different sound triggers.
  • The results yielded a surprising discovery that could lead to a better understanding of the disorder.

Misophonia, or sound aversion, is a disorder that causes extreme negative reactions to certain noises.

To learn more about what causes the disorder, researchers at The Ohio State University (OSU) studied people with misophonia and people without misophonia to see what happens in the brain when certain sounds are present.
