Abstract Interoception refers to the sensing of internal state body and encompasses various bodily axes. Yet many interoceptive signals display unique qualities. The heart, lungs, stomach each have their distinct frequencies, afferent pathways, respective functions. At same time these organs has been demonstrated interact with neural activity behaviour. To what extent then should different be treated as separate modalities in interoception? We here aim answer this question by assessing human participants whether phase visceral rhythms is coupled corticospinal excitability motor system, coupling happens an organ-specific or organ-general manner. combined continuous physiological recordings single pulse Transcranial Magnetic Stimulation (TMS) probe phase-amplitude between cardiac, respiratory, gastric rhythm amplitude Motor Evoked Potentials (MEP). All three contributed MEP similar effect sizes at group level. However, we found no relation strengths organs. Thus, displaying high one organ did not necessarily other organs, suggestive profiles. There was also link self-reported awareness actual coupling, suggesting are dimensions interoception. Together results show that mediated least partially independent mechanisms.
