This study uses fMRI and dynamic causal modelling to show the habenula modulates midbrain and cortical pathways with both inhibitory and excitatory effects during negative reward prediction error tasks.

This study examines the relationship between neural activation during reappraisal tasks and individual differences in emotion regulation, finding no shared overlap across three measures and highlighting methodological challenges in fMRI research.

The paper investigates neural circuitry differences during cognitive restructuring in depressive and anxiety disorders using fMRI, finding distinct activation and connectivity patterns associated with symptom severity.

This study uses fMRI and DCM to show that insula and pulvinar connectivity patterns mediate precision-weighted prediction in visual tasks, revealing a dual-route mechanism for predictive processing.

The paper investigates altered basal forebrain connectivity in depressive and anxiety disorders using resting-state fMRI and finds increased inhibitory connectivity from nucleus basalis of Meynert to the default mode network in clinical participants.

This study uses fMRI to compare brain activity during safety learning via conditioned inhibition and standard safety signals, finding distinct cortico-striatal circuits for each.

This study identifies a thalamo-centric neural signature in the mediodorsal thalamus involved in cognitive restructuring of negative self-beliefs using fMRI and Dynamic Causal Modelling.

This study investigates the role of subcortical structures in modulating the default mode network in humans using fMRI.
