Computational modelling reveals slower safety learning and threat extinction are associated with higher anxiety severity in remote fear conditioning

The paper uses computational modeling to show that higher anxiety severity is linked to slower safety learning and threat extinction in fear conditioning tasks.

Broadening the scope: Multiple functional connectivity networks underlying threat and safety signaling

The paper identifies multiple functional connectivity networks involved in threat and safety signaling during threat learning and extinction using fMRI and independent component analysis.

Evidence for distinct genetic and environmental influences on fear acquisition and extinction

This study uses twin data to show that fear acquisition and extinction have genetic and environmental influences, with moderate genetic overlap.

Posttraumatic Stress Disorder and the Social Brain: Affect-Related Disruption of the Default and Mirror Networks

This study investigates social cognitive impairments in PTSD using fMRI, finding hyperactivation to emotional stimuli in social brain networks, linked to symptom severity and training outcomes.

The effects of the angiotensin II receptor antagonist losartan on appetitive versus aversive learning

This study investigates how losartan affects appetitive versus aversive learning in humans using a reinforcement learning task, finding it enhances learning from positive outcomes more than negative ones.
