Interoceptive predictions in the brain

Open access

Abstract

Intuition suggests that perception follows sensation and therefore bodily feelings originate in the body. However, recent evidence goes against this logic: interoceptive experience may largely reflect limbic predictions about the expected state of the body that are constrained by ascending visceral sensations. In this Opinion article, we introduce the Embodied Predictive Interoception Coding model, which integrates an anatomical model of corticocortical connections with Bayesian active inference principles, to propose that agranular visceromotor cortices contribute to interoception by issuing interoceptive predictions. We then discuss how disruptions in interoceptive predictions could function as a common vulnerability for mental and physical illness.

  • Barrett and Simmons (2015) identified the periaqueductal gray as a key midbrain structure for receiving interoceptive information from within the body.

    “Barrett and Simmons (2015) identified previously the periaqueductal gray as a key midbrain structure for receiving interoceptive information from within the body (also see Wiens, 2005).”

    From How Processing of Sensory Information From the Internal and External Worlds Shape the Perception and Engagement With the World in the Aftermath of Trauma: Implications for PTSD (2021) · cites this paper as Barrett and Simmons, 2015

    In “The interoceptive system” (page unavailable), the paper places the periaqueductal grey in a descending pathway from visceromotor cortex toward the spinal cord. It describes signals from the body ascending through other structures, not the periaqueductal grey. Thus, its account does not identify that structure as a key recipient of interoceptive information from the body. (LLM, conf=0.85)

  • Interoceptive signals indicating physiological deviation (prediction error) from homeostatic limits have obvious adaptive significance (e.g., thermoregulation).

    “Similarly, interoceptive signals indicating physiological deviation (prediction error) from homeostatic limits have obvious adaptive significance (e.g., thermoregulation) (Barrett and Simmons, 2015;Seth and Friston, 2016).”

    From Physiological feelings (2019) · cites this paper as Barrett and Simmons, 2015

    The Abstract identifies temperature as an interoceptive sensation, and ‘Interoceptive sensation is largely prediction’ links interoceptive prediction errors to homeostatic control. But the Conclusion defines prediction errors as failures of predictions to account for incoming sensations, not specifically as physiological deviations from homeostatic limits; the paper does not give thermoregulation as an example here. Page numbers are unavailable in our copy. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Prediction errors in interoceptive signaling extend closed-loop homeostatic reflex control to modify emotional response programs to better accomplish output goals and underpin affective feelings states.

    “Prediction errors in interoceptive signaling thus extends closed-loop homeostatic reflex control to modify emotional response programs to better accomplish output goals and underpin affective feelings states.”

    From Physiological feelings (2019) · cites this paper as Barrett and Simmons (2015)

    In “Prediction error in agranular cortex,” the paper proposes that interoceptive prediction errors can lead visceromotor regions to change their outputs to the body. “Interoceptive sensation is largely prediction” links interoception to affective properties of experience. The paper does not specifically describe this as extending closed-loop reflex control to modify emotional response programs toward output goals, and it presents the mechanism as a model rather than an established result. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • These feelings arise from integrative representation of (conscious and unconscious) afferent interoceptive information of the internal physiological state of the body, in relation to 'top-down' predictive models of the self.

    “These feelings arise from integrative representation of (conscious and unconscious) afferent interoceptive information of the internal physiological state of the body, in relation to "top-down" predictive models of the self.”

    From Physiological feelings (2019) · cites this paper as Barrett and Simmons (2015)

    The Conclusion (page unavailable) says experienced interoceptive perceptions arise from predictions shaped by prior experience and constrained by incoming bodily signals. The ‘Interoceptive sensation is largely prediction’ section links affective feelings to interoception, but the passages do not establish the claim’s conscious/unconscious distinction or describe the predictions specifically as models of the self. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • Viscerosensory (interoceptive) feedback is judged against homeostatic set-points to drive affective feelings states and regulation of allostatic/homeostatic balance.

    “Viscerosensory (interoceptive) feedback is judged against homeostatic set-points to drive affective feelings states and regulation of allostatic/homeostatic balance.”

    From Physiological feelings (2019) · cites this paper as Barrett and Simmons (2015)

    In “Active interoceptive inference” (page unavailable), the paper links interoception to affective properties and describes prediction errors as constraining allostatic control. The Conclusion (page unavailable) says incoming bodily sensations keep the brain’s predictions in check. It does not describe feedback as being judged against homeostatic set-points; its account instead emphasizes anticipatory predictions shaped by sensory input. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
