This study investigates hemispheric differences in interoceptive processing in psychiatric disorders using neuroimaging, finding dysgranular mid-insula dysfunction in anxiety, depression, and eating disorder patients.

This study examines how focal brain damage affects voluntary respiratory and motor control, finding impaired regulation and increased anxiety in specific brain regions.

This study uses LIFU to target brain regions involved in the HEP and finds that PI modulation decreases HEP amplitudes.

The paper examines fear learning in individuals with major depressive disorder (MDD) and anxiety disorder plus MDD (AD+MDD), finding increased sustained threat circuitry response in AD+MDD during fear acquisition.

This study uses Bayesian and frequentist methods to analyze resting-state fMRI data from females with GAD, finding reduced functional connectivity in specific brain regions.

This study investigates neural responses to gastrointestinal sensations using a vibrating capsule, showing improved perceptual accuracy and correlated neural activity.

The paper introduces the HED model to characterize PPG waveforms, showing it captures physiological changes with high precision in a pharmacological study.

The paper replicates previous findings showing healthy individuals adjust prior expectations and interoceptive precision estimates based on task context using an active inference approach.

This paper develops a computational model to understand factors influencing antidepressant non-adherence by simulating decision-making processes.
