Your Hidden Sixth Sense: The Neuroscience of Feeling Your Body

Interoception—your brain's ability to sense signals from within your body—is emerging as fundamental to understanding emotions, decision-making, and mental health. With new neuroscience tools and a 2021 Nobel Prize spotlighting the field, scientists are rapidly mapping how bodily signals shape consciousness and behavior, with potential applications in treating obesity, chronic pain, and anxiety. This research challenges the historical separation of mind and body, showing that emotions and reasoning are deeply rooted in bodily sensation.
