Heartbeat evoked potentials reflect interoceptive awareness during an emotional situation.

ABSTRACT: Interoception, the ability to perceive internal bodily signals, involves various mental processes. This study investigated moments when individuals experienced a change in their interoceptive state. Interoception affects the subjective feelings of emotions. However, whether changes in interoceptive processing occur when visceral changes are perceived as interoceptive sensations remains unclear. This study examined the psychophysiological markers of perceptual changes in the interoceptive state using heartbeat evoked potentials (HEP). Emotional photos were viewed by participants who were asked whether they experienced changes in their interoceptive state. The results showed that the HEP amplitude increased when participants had subjective awareness of changes in their interoceptive state. N
