Description

<p>Interoception is the perception of the internal bodily state, including the autonomic nervous system. Recently, heartbeat evoked potentials (HEP) have been proposed as a measure of interoception. HEP is considered a brain potential with high temporal resolution reflecting afferent signals from the cardiovascular system without the need for subjective reporting. HEP relates to various cognitive responses such as attention, emotion, self-awareness, and symptoms of psychiatric disorders. In this review, we overview the studies of HEP, which is expected to be a useful index of mind-body interactions, and discuss the relationship between interoception and cognitive functions.</p>
