ABSTRACT Interoception, the internal perception of bodily states such as heartbeat and hunger, plays a crucial role in shaping cognitive emotional states. Since postural control affects processing, exploring effects on interoception could help uncover neural mechanisms underlying its cognition emotion. In this study, we aimed to investigate how different postures affect by using heartbeat‐evoked potentials (HEPs), which reflect cortical processing cardiac signals. Two experiments were conducted; Experiment 1 involved 47 healthy male participants comparing sitting standing postures, 2 24 stable unstable conditions. HEPs analyzed cluster‐based permutation analysis identify statistically significant spatiotemporal clusters. 1, clusters identified over central electrodes (Cz, C1, C2, FCz, FC1) within post‐R‐wave interval 304–572 ms, revealing significantly lower HEP amplitudes during compared [ W = 80, p < 0.001, r 0.62]. 2, t (20) 2.9, 0.0099, d Furthermore, found no correlations between changes physiological activity periodic aperiodic brain activity. These findings suggest differences modulate interoceptive with attenuating amplitudes, probably because redistribution attentional resources from somatosensory (proprioceptive) vestibular necessary for maintaining posture. This study provides insights into posture–interoception interaction.
