Heartbeat perception is causally linked to frontal delta oscillations [PDF]

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 ...

Short-Term Fasting and Ingestion of Caloric Drinks Affect Heartbeat-Evoked Potentials and Autonomic Nervous System Activity in Males

Frontiers in Neuroscience, 2021
Central nervous systems receive and process information from the internal and external environment to maintain homeostasis. This includes interoceptive awareness of the organism’s nutritional state.

An Introduction to Predictive Processing Models of Perception and Decision‐Making

Topics in Cognitive Science, EarlyView., 2023
Abstract The predictive processing framework includes a broad set of ideas, which might be articulated and developed in a variety of ways, concerning how the brain may leverage predictive models when implementing perception, cognition, decision‐making, and motor control.

Interoceptive dimensions across cardiac and respiratory axes [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2016
Interoception refers to the sensing of signals concerning the internal state of the body. Individual differences in interoceptive sensitivity are proposed to account for differences in affective processing, including the expression of anxiety. The majority of investigations of interoceptive accuracy focus on cardiac signals, typically using heartbeat ...

Interoceptive cardiac signals selectively enhance fear memories. [PDF]

Journal of Experimental Psychology: General, 2019
Fear is coupled to states of physiological arousal. We tested how learning and memory of threat, i.e. conditioned fear, is influenced by interoceptive signals. Forty healthy individuals were exposed to two threat (CS+, paired with electrocutaneous shocks) and two safety (CS-) stimuli, specifically time-locked to either cardiac ventricular systole (when

Cardiac and gastric interoception have distinct neural substrates [PDF]

, 2022
AbstractInteroception, or an awareness of the internal body state, guides agents in adaptive behavior by informing them of ongoing bodily signals, such as heart rate or energy status. However, it is still unclear whether the human brain represents the differences in the subjective experience of interoception differently. Hence, we directly compared the

The relationship between interoception and agency and its modulation by heartbeats: an exploratory study

Scientific Reports, 2022
Interoception, the sense of the internal physiological state of the body, theoretically underpins aspects of self-representation. Experimental studies link feelings of body ownership to interoceptive perception, yet few studies have tested for ...

Interpreting Anxiety Disorders From the Perspective of Interoceptive Computational Models. [PDF]

Brain Behav
Pathological anxiety stems from computational failures in interoception, where rigid threat beliefs amplify prediction errors. This review outlines how these mechanisms sustain maladaptive behaviors and cognitive biases. We synthesize a path forward by integrating computational models with targeted interventions to recalibrate this dysregulated process

Cardiac and Gastric Interoceptive Awareness Have Distinct Neural Substrates

eneuro, 2023
Abstract Interoceptive awareness, an awareness of the internal body state, guides adaptive behavior by providing ongoing information on body signals, such as heart rate and energy status. However, it is still unclear how interoceptive awareness of different body organs are represented in the human brain. Hence, we
