TLDR
A definition of interoception as based on subjective experience is proposed, and pleas for the use of specific vocabulary in addressing the many aspects that contribute to it are made.Abstract:
Over the course of a century, the meaning of interoception has changed from the restrictive to the inclusive. In its inclusive sense, it bears relevance to every individual via its link to emotion, decision making, time-perception, health, pain, and various other areas of life. While the label for the perception of the body state changes over time, the need for an overarching concept remains. Many aspects can make any particular interoceptive sensation unique and distinct from any other interoceptive sensation. This can range from the sense of agency, to the physical cause of a sensation, the ontogenetic origin, the efferent innervation, and afferent pathways of the tissue involved amongst others. In its overarching meaning, interoception primarily is a product of the central nervous system, a construct based on an integration of various sources, not per se including afferent information. This paper proposes a definition of interoception as based on subjective experience, and pleas for the use of specific vocabulary in addressing the many aspects that contribute to it.read more

"Cognitive, social, and physiological determinants of emotional state": Erratum
TL;DR: The problem of which cues, internal or external, permit a person to label and identify his own emotional state has been with us since the days that James first tendered his doctrine that "the bodily changes follow directly the perception of the exciting fact".

Interoception and emotion.
TL;DR: This work describes the afferent signalling, central processing, and neural and mental representation of internal bodily signals in interoception, and describes the recognition of dissociable psychological dimensions of interoceptions.

Can Interoception Improve the Pragmatic Search for Biomarkers in Psychiatry
TL;DR: It is concluded that interoception represents a viable avenue for clinical and translational research in psychiatry, with a well-established conceptual framework, a neural basis, measurable biomarkers, interdisciplinary appeal, and transdiagnostic targets for understanding and improving mental health outcomes.

Visceral Signals Shape Brain Dynamics and Cognition.
TL;DR: How the heart and gastrointestinal tract intrinsically generate their own electrical activity, thereby continuously sending information to the brain, is discussed in relation to interpretative frameworks regarding the functional role of visceral inputs.

The Heartbeat Counting Task Largely Involves non-Interoceptive Processes: Evidence from both the Original and an Adapted Counting Task
TL;DR: The HCT task is largely contaminated by the influence of non-interoceptive processes, and IAcc scores are drastically reduced when asking participants to avoid relying on non-Interoceptive signals and to only report the heartbeats they perceive.

Central nervous system control of food intake
TL;DR: A model is described that delineates the roles of individual hormonal and neuropeptide signalling pathways in the control of food intake and the means by which obesity can arise from inherited or acquired defects in their function.

Cognitive, social, and physiological determinants of emotional state.
TL;DR: The problem of which cues, internal or external, permit a person to label and identify his own emotional state has been with us since the days that James (1890) first tendered his doctrine that "the bodily changes follow directly the perception of the exciting fact, and that our feeling of the same changes as they occur is the emotion" (p. 449) as mentioned in this paper.

How do you feel? Interoception: the sense of the physiological condition of the body.
TL;DR: Functional anatomical work has detailed an afferent neural system in primates and in humans that represents all aspects of the physiological condition of the physical body that might provide a foundation for subjective feelings, emotion and self-awareness.
