Context-dependent effects of ketamine on emotional evidence integration

This study examines how ketamine affects emotional evidence integration in changing environments, finding it shifts the balance between recent and past information based on volatility.

Cardiac belief updating from volatile physiological afferents

This paper introduces a computational framework to measure cardiac interoceptive sensitivity by analyzing heart rate variability and finds it is weak in healthy individuals but varies significantly across participants.

Low-intensity focused ultrasound to human amygdala reveals a causal role in ambiguous emotion processing and alters local and network-level activity

This study uses low-intensity focused ultrasound to modulate human amygdala activity and finds it alters emotional processing and reaction times to ambiguous stimuli.

Environmental dynamics shape human learning: change points versus random walks

This study shows humans adjust their learning to environmental dynamics, distinguishing between abrupt change points and gradual random walks.

Differences in layer-specific activation of the insula during interoceptive vs. exteroceptive attention

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.

Quantifying decision-making in dynamic, continuously evolving environments

The paper investigates how neural responses adapt to different environments in continuous decision-making tasks, showing changes in EEG signals reflect shifts in evidence accumulation strategies.

Auditory mismatch responses are differentially sensitive to changes in muscarinic acetylcholine versus dopamine receptor function

This study investigates how muscarinic acetylcholine and dopamine receptor function affect auditory mismatch negativity (MMN) in schizophrenia, finding differential sensitivity to these neuromodulators.

TAPAS: an open-source software package for Translational Neuromodeling and Computational Psychiatry

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

State anxiety biases estimates of uncertainty during reward learning in volatile environments

The paper shows that state anxiety in healthy individuals leads to biased uncertainty estimates and impaired reward learning in volatile environments.

Ketamine Affects Prediction Errors About Statistical Regularities: A Computational Single-Trial Analysis of the Mismatch Negativity

This study shows ketamine reduces high-level prediction errors in a roving MMN paradigm, supporting the role of NMDAR in hierarchical Bayesian inference.

Focus of attention modulates the heartbeat evoked potential

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