“…The level of interoceptive awareness has been mostly quantified through different tasks of heartbeats' sensation [48][49][50][51]. The validity of some of those tasks has been questioned because of different biases related to the specificity of the measurements [52,53], and because of confounding factors [54,55]. The reported links between atypical or disrupted interoceptive ability include different pathological conditions [19,26], but also in abnormal emotion regulation [56], emotion sensitivity/recognition [57], emotion categorization [58], and overall emotional processing [59].…”

Recent experimental evidence on patients with disorders of consciousness revealed that observing brain-heart interactions helps to detect residual consciousness, even in patients with absence of behavioral signs of consciousness. Those findings support hypotheses suggesting that visceral activity is involved in the neurobiology of consciousness, and sum to the existing evidence in healthy participants in which the neural responses to heartbeats reveal perceptual and self-consciousness. More evidence obtained through mathematical modeling of physiological dynamics revealed that emotion processing is prompted by an initial modulation from ascending vagal inputs to the brain, followed by sustained bidirectional brain-heart interactions. Those findings support long-lasting hypotheses on the causal role of bodily activity in emotions, feelings, and potentially consciousness. In this paper, the theoretical landscape on the potential role of heartbeats in cognition and consciousness is reviewed, as well as the experimental evidence supporting these hypotheses. I advocate for methodological developments on the estimation of brain-heart interactions to uncover the role of the heart in the origin, levels, and contents of consciousness. The ongoing evidence depicts interactions further than the cortical responses evoked by each heartbeat, suggesting the potential presence of non-linear, complex, and bidirectional communications between brain and heartbeat dynamics. Further developments on methodologies to analyze brain-heart interactions may contribute to a better understanding of the physiological dynamics involved in homeostatic-allostatic control, cognitive functions, and consciousness.

“…Future research should aim to better incorporate within-task measures of cardiovascular activity as heartbeat strength and blood flow may play a significant role in heartbeat perception. Indeed, recent research has demonstrated that heartbeat-evoked responses co-fluctuate with beat-to-beat changes in stroke volume (66). In addition, a main limitation of the study is that while respiration is speculated to play a role on heartbeat strength, respiration was not being measured, and thus these are currently only speculations and do not allow for us to draw strong conclusions.…”

Individuals vary in their ability to perceive, as conscious sensations, signals like the beating of the heart. Tests of such interoceptive ability are, however, constrained in nature and reliability. Performance of the heartbeat tracking task, a widely used test of cardiac interoception, often corresponds well with individual differences in emotion and cognition, yet is susceptible to reporting bias and influenced by higher order knowledge, e.g. of expected heart rate. The present study introduces a new way of assessing cardiac interoceptive ability, focusing on sensitivity to short-term, naturalistic changes in frequency of heartbeats. At rest, such heart rate variability typically reflects the dominant influence of respiration on vagus parasympathetic control of the sinoatrial pacemaker. We observed an overall tendency of healthy participants to report feeling fewer heartbeats during increases in heart rate, which we speculate reflects a reduction in heartbeat strength and salience during inspiratory periods when heart rate typically increases to maintain a stable cardiac output. Within-participant performance was more variable on this measure of cardiac interoceptive sensitivity relative to the 'classic' heartbeat tracking task. Our findings indicate that cardiac interoceptive ability, rather than reflecting the veridical monitoring of subtle variations in physiology, appears to involve more interpolation wherein interoceptive decisions are informed by dynamic working estimates derived from the integration of afferent signalling and higher order predictions.

“…Since disrupted sleep in nightmare disorder is not limited to REM sleep, but also showed alterations in NREM sleep, especially NREM to REM transitions ( Blaskovich et al, 2020 , Blaskovich et al, 2019 ), future studies may investigate the HEP in more detail focusing on the more transient, microstructural dimensions of sleep periods. Moreover, future studies should examine and exclude the confounding effect of cardiac parameters on HEP with more refined techniques ( Buot et al, 2021 ). We should note that with respect to cardiac parameters our two studies showed some differences.…”

The heartbeat evoked potential is a questionable biomarker in nightmare disorder: A replication study

Highlights Perogamvros et al. (2013) examined heart beat evoked potential (HEP) in nightmare sufferers. Increased HEP was proposed to be a robust biomarker in nightmare disorder. We aimed to replicate the original study in two separate and larger databases. We did not confirm the original finding showing differential HEP in REM sleep. Our data cast doubts on the utility of HEP as a biomarker in nightmare disorder.
