The paper tests a computational model of perceived control over breathing by analyzing data from a novel behavioral task, finding that perceived control depends on interoceptive outcomes and prediction errors.

The paper identifies convergent and selective functional zones in the insula using fMRI data, revealing a hierarchical convergence architecture across pain, appetitive, aversive, and cognitive control domains.

This study uses 3T fMRI and multivariate analysis to distinguish functional activity of adjacent somatosensory nuclei in the brainstem, thalamus, and S1, showing improved decoding compared to univariate methods.

The paper applies Bayesian workflow to improve parameter and model identifiability in hierarchical Bayesian models using multivariate behavioural data from a reward learning task.

This study uses fMRI and a Bayesian model to show that the anterior insula is involved in thermoceptive predictions and prediction errors in humans.

This study extends an interoceptive learning task to measure prediction certainty continuously and applies a learning model to analyze how learning rates relate to stimuli valence and mental health factors.

This paper introduces an automated method to measure respiratory interoception and metacognition using a computer-controlled apparatus.

The paper shows that baseline psychological traits like anxiety and neuroticism, not physiological changes, are linked to AMS symptoms at high altitude.

This study investigates how anxiety relates to interoceptive processing of breathing using fMRI and computational models, finding that anxiety traits affect interoceptive prediction certainty and errors in the anterior insula.

This study investigates the relationship between breathlessness symptoms, mood, and interoception in asthma patients and healthy controls, finding that negative mood affects interoceptive sensitivity and attention.

The paper introduces a task and analysis procedure to quantify breathing-related interoception dimensions using simulated and empirical data.

TAPAS provides open-source tools for computational assays in psychiatry to support differential diagnosis and treatment prediction through end-to-end pipelines.

The paper tests the Neural Pain Signature (NPS) in breathlessness and somatomotor tasks, finding overlap but not equivalence, and identifies limitations in its specificity.

The paper introduces a remote, automated, and MRI-compatible system for delivering inspiratory resistive loads to study interoception in neuroimaging studies.

This study investigates how psychological and neural factors influence variability in opioid response to breathlessness, finding negative affect and brain activity correlate with reduced efficacy.

The paper investigates how athletes' brains process breathing perceptions during exercise, finding enhanced anticipatory brain activity and connectivity in interoceptive networks compared to sedentary individuals.

This study shows pulmonary rehabilitation reduces breathlessness in COPD by altering brain activity related to learned associations, with greater baseline brain activity linked to larger treatment benefits.

The paper tests a Bayesian model of breathlessness perception by linking psychological traits to brain activity and variability in subjective breathlessness experiences.
