Interoception

The body's sense of itself — the felt visceral state through which the brain tracks the homeostatic condition of the organism. In the dominant anatomical model the afferent pathway runs through small-diameter spinothalamic fibres into the dorsal posterior insula and is re-represented in the right anterior insula as conscious feeling; the post-2013 predictive-processing alternative inverts the directionality and reads interoception as inference about expected body state rather than direct readout. A reading list assembled around the term — Augustine's 1996 insular anatomy, Damasio's somatic-marker hypothesis, Craig's 2002 reformulation, Critchley's heartbeat-detection paradigm, Garfinkel's three-way accuracy/sensibility/awareness refinement, Naqvi and Bechara's lesion-method evidence on insula and addiction, the predictive-processing counter-statement (Seth; Barrett and Simmons), and the 2018 Khalsa Roadmap as the field's consensus orientation.

Reading the interoception literature

A chronological and conceptual reading list for the contemporary interoception literature — from Sherrington's 1906 coinage and Augustine's anatomy through Damasio's somatic-marker prehistory, Craig's 2002 reformulation as a distinct sensory modality, Critchley's heartbeat-detection paradigm, Naqvi and Bechara's causal-evidence lesion work, the post-2013 predictive-processing alternative (Seth; Barrett and Simmons), Garfinkel's three-way methodological refinement, and the 2018 Khalsa Roadmap. Where the disagreements live and how the construct arrived at its present shape.
