The paper investigates neural mechanisms of social camouflaging in autism using fMRI and finds hyperconnectivity between specific brain networks linked to mental health costs.

The paper partially replicates and generalizes Bramson et al.'s 2023 findings on functional anatomical shifts in emotion action control related to anxiety using fMRI data from a different sample and paradigm.

This study shows oxytocin, but not vasopressin, reduces willingness to harm others by increasing guilt and shame for intentional harm.

This study finds that autistic children show different gaze patterns and heightened arousal and brain reward responses to happy faces, which are linked to adaptive difficulties and symptom severity, contradicting the social motivation hypothesis.

The paper identifies the right inferior frontal gyrus as a key node and regulator in the basal ganglia-thalamocortical response inhibition circuit using fMRI and causal modeling.

The paper examines associations between Internet Use Disorder symptom domains and brain structure/function in a dimensional neuroimaging study, finding opposing effects on striatal networks and volumes.

This study shows that individuals with higher autistic traits have reduced amygdala responses to imitation but increased mirror neuron system activity and connectivity, which may compensate for social deficits.

The paper identifies brain systems mediating domain-general and emotion-specific inhibitory control using fMRI in a large cohort, showing distinct roles for ventral striatum and orbitofrontal cortex.

This study investigates how oxytocin modulates threat-specific amygdala reactivity in humans and finds that serotonergic mechanisms are critical for this effect.

The paper investigates how serotonin and childhood maltreatment interact to affect brain structure and anxious avoidant behavior using a TPH2 imaging genetics approach in humans.

The paper shows that threatening faces are better remembered than non-threatening ones after 1.5 years, with differential neural encoding in specific brain regions.

The paper identifies shared and process-specific neural representations of vicarious pain using fMRI and multivariate pattern analysis.

The paper uses inter-subject phase synchronization to analyze fMRI data and identifies distinct neural networks associated with physical pain empathy, but not affective pain.

This study shows oxytocin influences sex differences in human mate choice by altering preferences for short-term vs. long-term relationships.

This study investigates how alexithymia and autism traits independently and interactively influence interoceptive dysregulations in pain empathy using a dimensional neuroimaging approach in healthy subjects.

This study finds that romantic jealousy is linked to heightened neural responses to angry faces and increased functional connectivity in fronto-striatal and limbic regions.

This study shows that oxytocin increases social reward in women but not men during sharing with friends, linked to reduced amygdala and insula activity and functional connectivity in women with higher attachment anxiety.
