This study shows ketamine reduces habenula activity during aversive learning in humans, supporting preclinical findings on its antidepressant mechanisms.

This study shows that early maternal separation in rats increases prefrontal mitochondrial function and protects against stress-induced negative cognitive bias in adulthood.

This study investigates how early life stress affects probabilistic reversal learning in rats and examines the role of noradrenergic and serotonergic systems in modulating this effect.

This study shows anxious individuals are more sensitive to changes in outcome variability and value differences in dynamic environments, displaying distinct learning patterns under different volatility and noise conditions.

The paper examines how real-world environmental uncertainty interacts with intolerance of uncertainty to influence anxiety and depression symptoms over time.

This study links probabilistic learning with effort-based decision making, showing that effort depends on internal value beliefs and is disrupted in anhedonia.

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 paper develops a novel paradigm to study infant decision-making and applies computational models to identify subtypes with distinct cognitive profiles.

The paper shows that uncertainty affects prediction error minimization and agency judgments in the action-perception loop, with differences observed in autism traits.

This study investigates how dopamine affects attention and learning in Parkinson's disease patients on and off medication using behavioral and fMRI data.
