Interoception

topic

Interoception is the brain's capacity to sense, integrate, and interpret signals from the internal body — heartbeat, breathing pattern, muscle tension, gut sensations, temperature, pain, hunger, nausea, and the diffuse somatic signals that constitute the physical substrate of emotional experience — with interoceptive accuracy (correctly identifying what the body is experiencing) and interoceptive sensibility (the degree of attention paid to body signals) together determining how fully emotional information from the body is available to conscious awareness and decision-making.

Role

Interoception is the neurological foundation of emotional awareness — the sensory channel through which the body communicates emotional information to the brain before verbal language has processed it, producing the 'gut feelings,' 'heart feelings,' and somatic intuitions that precede and inform conscious emotional experience. Research by Antonia Damasio established that interoceptive deficits produce decision-making impairment even in individuals with intact analytical cognition — establishing that emotional body signals are not noise to be suppressed in favor of rational thinking but essential information that proper decision-making requires. Most people raised in intellectualizing cultures have developed the habit of overriding interoceptive signals with cognitive analysis, producing the emotional disconnection that makes them feel 'out of touch' with their own feelings.
