Stretch-induced muscle responses under threat vs safety

This study investigates how threat influences motor preparation and stretch reflexes during reaching tasks, finding direction-selective modulation of long-latency reflexes under threat.

Testosterone Administration Modulates Competitive Choice via Ventral Striatum and TPJ

This study shows testosterone increases sensitivity to outcome feedback in competitive decision-making and modulates neural activity in ventral striatum and TPJ.

Improving emotion control in social anxiety by targeting rhythmic brain circuits

This study uses non-invasive brain stimulation to enhance theta-gamma phase-amplitude coupling in socially anxious individuals, improving control over approach-avoidance behaviors.

Spine-brain dynamics during human defensive threat-reactions

This study investigates how bradycardia during threat conditioning modulates spinal-brain connectivity in humans, revealing its role in defensive action preparation.

How distributed subcortical integration of reward and threat may inform approach-avoidance decisions

This study shows subcortical integration of reward and threat information before approach-avoidance decisions, challenging theories of separate processing.

Defensive freezing sharpens threat-reward information processing during approach-avoidance decision making

This study shows that defensive freezing enhances threat-reward processing in the dACC during approach-avoidance decisions, improving decision-making under threat.

Integrating stereotypes and factual evidence in interpersonal communication

The paper examines how stereotypes and factual evidence are integrated in communication, finding brain structure and early social experiences influence this process.

The neurocomputational link between defensive cardiac states and approach-avoidance arbitration under threat

The paper links bradycardia states to approach-avoidance decision-making under threat, showing amygdala and dACC involvement in integrating value and physiological states.

No evidence for a link between childhood (6-10y) cellular aging and brain morphology (12y) in a preregistered longitudinal study.

This study investigates whether childhood cellular aging markers predict brain morphology in adolescence but finds no significant associations.

Specific amygdala and hippocampal subfield volumes in social anxiety disorder and their relation to clinical characteristics; an international mega-analysis

This study identifies specific amygdala and hippocampal subfield volume differences in social anxiety disorder compared to healthy controls, with associations to comorbid conditions.

Developmental shift in testosterone influence on prefrontal emotion control

This study shows that testosterone's effect on prefrontal emotion control shifts from enhancing to impairing neural control during adolescence to young adulthood.

Predicting Math Ability using Working Memory, Number Sense, and Neurophysiology in Children and Adults

This study examines the relationship between resting-state beta oscillations, working memory, number sense, and mathematical ability in children and adults, finding no mediation but highlighting differences in aperiodic activity.

Defensive freezing and its relation to approach-avoidance decision-making under threat

This study investigates how threat-induced bradycardia influences approach-avoidance decisions, finding that it interacts with subjective value and action-context to affect choice behavior.

Improving emotional-action control by targeting long-range phase-amplitude neuronal coupling.

This paper demonstrates that targeted brain stimulation enhancing theta-gamma phase-amplitude coupling improves emotional-action control in a social-emotional task.

Patients with ventromedial prefrontal lesions show an implicit approach bias to angry faces

This study finds that patients with ventromedial prefrontal cortex lesions show an increased approach bias to angry faces, linked to impulsivity and lesion size.

Human lateral Frontal Pole contributes to control over social-emotional behaviour

This study identifies the lateral frontal pole as a key region for social-emotional regulation through neuroimaging and connectivity analyses in humans.

Eye-movement intervention enhances extinction via amygdala deactivation

This study shows that eye-movement interventions reduce fear recovery by temporarily deactivating the amygdala during extinction learning, similar to working memory tasks.

Stress matters: a double-blind, randomized controlled trial on the effects of a multispecies probiotic on neurocognition

This study investigates the effects of a multispecies probiotic on neurocognition in healthy volunteers, finding it improves working memory under stress but not emotion regulation or cognitive control.
