Interoception: Synthesizing Insights and Charting New Frontiers.

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.

Abstract

This chapter is dedicated to the intellectual legacy of A.D. Bud Craig and advancing the understanding of interoception. The chapter is organized into three critical domains of interoceptive research: Bodily Self, Emotion, and Subjective Time. Beginning with foundational neuroanatomical research on temperature and pain processing, the volume progresses to explore how interoceptive signals integrate to form our bodily self-representation and emotional experiences. This leads to discussion of the interoceptive self and its foundation role in emotional experience. Finally, this culminates in how interoception shapes our perception of time, including experiences in altered states of consciousness. This exploration into interoception points to promising future research focused on computational modeling of interoceptive processing, personalized treatment approaches based on interoceptive principles, and clinical applications for psychiatric, neurological, and pain conditions. In this chapter, we aim to outline the goals of this collection and the remaining gaps in the continuance of Bud Craig's seminal career.
