Intrinsic, dynamic and effective connectivity among large-scale brain networks modulated by oxytocin

This study investigates how oxytocin modulates effective and dynamic connectivity in brain networks related to social-emotional behavior using resting-state fMRI data from 200 healthy subjects.

Beyond fear centers: a distributed fMRI-based neuromarker for the subjective experience of fear

The paper uses fMRI and machine learning to identify a distributed neural signature predictive of subjective fear across multiple cohorts, showing it differs from other negative affect states.

Oxytocin modulates the intrinsic dynamics between attention-related large scale networks

This study investigates how oxytocin modulates intrinsic functional dynamics between attention-related large-scale brain networks in humans.

Oxytocin facilitates empathic- and self-embarrassment ratings by attenuating amygdala and anterior insula responses

This study shows oxytocin increases empathy and self-embarrassment ratings while reducing amygdala and insula activity and physiological arousal in response to embarrassment.

Sex- and Context-dependent Effects of Oxytocin on Social Reward Processing

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.

Oxytocin enhancement of emotional empathy: generalization across cultures and effects on amygdala activity

This study shows oxytocin enhances emotional empathy across cultures and sexes, reduces amygdala activity, and modulates amygdala connectivity with the insula, particularly in individuals with trait autism.
