Attention to cardiac sensations enhances the heartbeat-evoked potential during exhalation

iScience
Summary: Respiration and cardiac activity intricately interact through complex physiological mechanisms. The heartbeat-evoked potential (HEP) is an EEG fluctuation reflecting the cortical processing of cardiac signals.

Functional movement disorder is associated with abnormal interoceptive brain activity: a task-based functional MRI study

Frontiers in Psychiatry
BackgroundAberrant interoceptive processing has been hypothesized to contribute to the pathophysiology of functional neurological disorder, although findings have been inconsistent.

No differences between remote and laboratory-based testing of cardiac interoceptive accuracy using the phase adjustment task

Scientific Reports
In recent years, there has been an increased interest in remote testing methods for quantifying individual differences in interoception, the perception of the body’s internal state.

Atypical automatic processing of interoceptive information in adolescents with alexithymia

Journal of Affective Disorders Reports
Background: Alexithymia, characterized by impaired emotional identification and expression, exhibits conceptual and neuroanatomical overlap with atypical interoception - the ability to perceive and process bodily signals.

Recognition of others’ interoceptive states in those with and without eating disorders

BMC Psychiatry
Background The ability to recognize one’s own emotions is associated with one’s ability to recognize others’ emotions. Beyond the domain of emotion, however, the relationship between recognition of one’s own internal states (interoception) and others ...

Heartbeat perception is causally linked to frontal delta oscillations

Communications Biology
The ability to accurately perceive one’s own bodily signals, such as the heartbeat, plays a vital role in physical and mental health. However, the neurophysiological mechanisms underlying this ability, termed interoception, are not fully understood ...

Influence of alexithymia severity in the healthy population on the susceptibility to false interoceptive feedback

Frontiers in Psychology
Alexithymia is a psychological trait characterized by difficulty expressing emotions. Previous studies reported that individuals with higher alexithymia have a decreased sense of interoception, which is the sense of monitoring and controlling internal ...

Probing corporeal awareness in women through virtual reality induction of embreathment illusion

Scientific Reports
We capitalized on the respiratory bodily illusion that we discovered in a previous study and called ‘Embreathment’ where we showed that breathing modulates corporeal awareness in men.
