A Double Challenge: Cerebral Blood Flow During Concurrent Breath-Hold and Motor Task

This study examines how combined breath-holding and motor tasks affect cerebral blood flow, finding reduced perfusion increases in motor regions during the combined challenge.

Sensing the heart, seeing the world: Neural mechanisms of attentional allocation between interoception and exteroception

This study uses fMRI to compare neural networks for interoceptive and exteroceptive attention, finding distinct but interacting systems for internal and external sensory processing.

Autonomic challenge uncovers hidden link between diastolic blood pressure and mental imagery vividness

The paper investigates the link between diastolic blood pressure and mental imagery vividness using an autonomic challenge, finding that elevated diastolic blood pressure predicts reduced imagery vividness.

A hierarchical Bayesian model reveals increased precision weighting for afferent cardiac signals, and reduced anxiety, as a function of interoceptive training

This paper shows that interoceptive training improves heartbeat perception accuracy and reduces anxiety, with computational models explaining the underlying changes in signal precision and noise parameters.

Relationship between systolic blood pressure and decision-making during emotional processing

The paper examines how systolic blood pressure changes during emotional processing affect decision-making, finding that increased SBP correlates with accuracy and slows response times during anger priming.

Oxytocin reduces interoceptive influences on empathy-for-pain in the anterior insula

This study investigates how oxytocin affects empathy-for-pain by modulating interoceptive signals, showing that OT reduces brain reactivity to pain-related stimuli during systole.

Absence of reliable physiological signature of illusory body ownership revealed by f ine-grained autonomic measurement during the rubber hand illusion

The paper tests if the rubber hand illusion alters autonomic activity but finds no reliable physiological changes.

Serotonergic Effects on Interoception

This study investigates how acute serotonin changes affect interoceptive cognition, finding that SSRIs enhance confidence in interoceptive judgments without altering cardiac or subjective effects.

Feeling the beat: Temporal and spatial perception of heartbeat sensations

This study investigates temporal and spatial perception of heartbeat sensations, finding no relationship between them but a link between spatial precision and state anxiety.
