Why is this relevant to emotion? Because every brain region that’s claimed to be a home of emotion in humans is a body-budgeting region within the interoceptive network. These regions, however, don’t react in emotion. They don’t react at all. They predict, intrinsically, to regulate your body budget. They issue predictions for sights, sounds, thoughts, memories, imagination, and, yes, emotions. The idea of an emotional brain region is an illusion caused by the outdated belief in a reactive brain.
