This study examines how anxiety-related traits are linked to subjective fear responses but not to altered threat-safety discrimination across different phases of fear conditioning.

This study shows that recent adversity reduces autonomic threat-safety discrimination and predicts higher depression levels later, with distinct brain activation patterns linked to these effects.

This study conducts a genome-wide association analysis of generalised anxiety symptom severity, identifying 80 significant variants and showing genetic correlations with other mental and physical health traits.

The paper examines how childhood adversity affects threat learning in healthy adults, finding reduced discrimination between danger and safety signals but not overgeneralization.

The paper examines whether similar affective experiences produce comparable physiological responses, finding strong evidence for individual variability in physiological responses to affective stimuli.

This study examines reliability and response prediction in fear conditioning across time and phases, finding limited individual-level longitudinal reliability but some cross-phase predictability.

This study investigates whether intolerance of uncertainty (IU) affects reward extinction, finding that IU is linked to increased corrugator activity to neutral cues during reward learning but not to valence ratings or SCRs.

The paper investigates individual differences in fear acquisition by linking questionnaire scores, physiological responses, and neural activation using multivariate analyses across two studies.

This study uses combined facial EMG-fMRI to show that the human startle reflex is modulated by valence-specific neural pathways involving the amygdala and brainstem.
