Cardiac interoception in Anorexia Nervosa: A resting‐state heartbeat‐evoked potential study

European Eating Disorders Review, 2023
AbstractObjectiveA deficit in interoception ‐ the ability to perceive, interpret and integrate afferent signals about the physiological state of the body ‐ has been shown in Anorexia Nervosa (AN), and linked to altered hunger sensations, body dysmorphia, and abnormal emotional awareness.The present high‐density electroencephalography (hdEEG) study aims

Respiratory and Cardiac Phase Coupling With Voluntary Actions Across Motor Tasks

Psychophysiology, Volume 63, Issue 2, February 2026.
ABSTRACT Bodily rhythms such as breathing and heartbeat influence perception and motor processes. Recent studies have indicated that breathing phases, particularly exhalation, synchronize with voluntary actions, potentially reflecting a general influence on motor intention.

Deletion of the TRPV1 channel attenuates afferent renal nerve responses to renal artery occlusion but not elevated renal pelvic pressure

The Journal of Physiology, Volume 604, Issue 3, Page 1415-1427, 1 February 2026.
Abstract figure legend Using wild‐type and Trpv1−/− rats, we assessed the contribution of TRPV1 channels to the activation of afferent renal nerve activity (ARNA) during renal artery occlusion, graded reductions in renal blood flow and elevated renal pelvic pressure.

How the heart shapes the mind: The role of cardiac interoception in the interaction between bodily reactions and self-related thoughts

Acta Psychologica
Our thoughts often drift away from the tasks at hand. Various factors influence this phenomenon, including changes in the external environment, individual cognitive characteristics, and fluctuations in bodily reactions.

Phase confusion: how inconsistent cardiac labelling obscures interoception research

Biological Psychology
Research on the interaction between interoception and external sensory processing has grown rapidly, with a key focus on how different phases of the cardiac cycle (systole and diastole) affect stimulus processing. This typically involves synchronizing stimulus presentation with specific cardiac phases.

Investigating the relationship between cardiac interoception and autonomic cardiac control using a predictive coding framework [PDF]

Autonomic Neuroscience, 2018
Predictive coding models, such as the 'free-energy principle' (FEP), have recently been discussed in relation to how interoceptive (afferent visceral feedback) signals update predictions about the state of the body, thereby driving autonomic mediation of homeostasis.

Sympathetic Shift and Insular Alteration: Unravelling the Link Between Anxiety and Heart Rate Variability in Parkinson's Disease

Movement Disorders, Volume 41, Issue 1, Page 179-189, January 2026.
Abstract Background Anxiety and autonomic dysfunction are frequent non‐motor symptoms of Parkinson's disease (PD). Their relationship, as well as the neural mechanisms underlying this relationship, remain unexplored. Objectives We aimed to investigate the relationship between cardiovascular functions and anxiety in PD and the structural neural changes ...

Cardiovascular Activity Predominantly Modulates Brain Dynamics in Non‐REM Sleep Transitions

Annals of the New York Academy of Sciences, Volume 1555, Issue 1, January 2026.
This study investigated the dynamics of the neural brain‐heart axis across sleep stages using EEG and ECG data from 50 healthy individuals. Applying a functional brain‐heart interplay model revealed reduced central control over heartbeat regulation, and sympathovagal influence on cortical function increased during deep non‐REM sleep. The study findings

Altered sense of agency in schizophrenia: the aberrant effect of cardiac interoceptive signals

Frontiers in Psychiatry
BackgroundSchizophrenia (SZ) is characterized by abnormalities in self-representation, including a disturbed sense of agency (SoA). The continuous processing of sensory information concerning the internal state of the body (interoception) is argued to be
