This chapter reviews the intellectual legacy of A.D. Bud Craig and advances understanding of interoception across three domains: bodily self, emotion, and subjective time. Beginning with foundational research on temperature and pain processing, it describes how interoceptive signals integrate to form bodily self-representation and emotional experiences, then culminates in how interoception shapes time perception, including in altered states of consciousness. The chapter points to future research on computational modeling of interoceptive processing, personalized treatments based on interoceptive principles, and clinical applications for psychiatric, neurological, and pain conditions, while outlining remaining gaps in continuing Craig's seminal career.
