What is the insula?
Quick Answer
The insula is a hidden part of the brain buried deep within the cerebral cortex. It helps process body feelings, emotions, taste, and awareness of internal states.
The Full Story
The insula lies folded deep inside the lateral sulcus, so it is not visible from the brain’s outer surface. It contributes to interoception, the sense of what is happening inside the body, such as hunger, heartbeat, or nausea. The insula also plays roles in emotion, pain perception, empathy, and the experience of disgust. Researchers study it in relation to addiction, anxiety, and how the brain turns body signals into conscious feelings.
