This study shows that serotonin reduces belief stickiness, improving state inference, and links this effect to the therapeutic benefits of SSRIs in obsessive-compulsive disorder.

The paper investigates layer-specific activation in the insula during interoceptive and exteroceptive attention tasks using fMRI and finds increased activity in upper cortical layers during interoceptive attention.

This study identifies a duration-dependent decision-making shift in chronic pain patients, showing reduced reliance on global expected value and increased context-dependent reinforcement history.

This study examines uncertainty processing in humans using computational models and neurochemical data, finding links between neurotransmitter levels and prediction errors in reversal learning.

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.

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

This study shows that attentional focus modulates the heartbeat evoked potential (HEP), with higher HEP amplitudes during interoceptive attention compared to exteroceptive attention.
