Interoception is the process by which the nervous system senses, integrates, stores, and represents information about the internal body state at conscious and unconscious levels. It encompasses a wide range of physiological systems, including the cardiac, respiratory, gastrointestinal, and urinary systems. Interoception is distinct from visceroception, which focuses specifically on signals from visceral organs. Interoceptive awareness refers to the ability to be aware of internal bodily sensations and has been studied in various contexts, including eating disorders. Interoceptive attention involves directing attention towards internal sensations, while interoceptive detection is the ability to detect the presence or absence of internal stimuli. Interoceptive magnitude refers to the intensity of internal sensations, and interoceptive discrimination is the ability to distinguish between different internal sensations. Interoceptive accuracy is the ability to accurately monitor changes in internal body state, and interoceptive insight is the metacognitive measure of the correspondence between subjective experience and behavior. Interoceptive sensibility refers to the self-perceived tendency to focus on internal sensations. Interoceptive self-report scales assess the ability to reflect on and describe interoceptive experiences. The article also discusses various measurement techniques and their applications in research and clinical settings. The study highlights the importance of interoception in mental health and provides a roadmap for further research and understanding of this complex phenomenon.Interoception is the process by which the nervous system senses, integrates, stores, and represents information about the internal body state at conscious and unconscious levels.
