Oxytocin modulates neurocomputational mechanisms underlying prosocial reinforcement learning

This study shows that oxytocin modulates prediction error encoding in the midbrain-sgACC pathway during prosocial learning, without affecting self-oriented learning.

Less is more: a dose-response account of intranasal oxytocin pharmacodynamics in the human brain

This study shows that lower doses of intranasal oxytocin have maximal effects on amygdala physiology, with subregion-specific responses and no disruption of cerebrovascular reactivity.

Analysis of structural brain asymmetries in Attention-Deficit/Hyperactivity Disorder in 39 datasets

This study analyzes structural brain asymmetries in ADHD using 39 datasets, finding small effects that do not meet study-wide significance thresholds.

Evidence for Similar Structural Brain Anomalies in Youth and Adult Attention-Deficit/Hyperactivity Disorder: A Machine Learning Analysis

This study uses machine learning to show that structural brain anomalies in ADHD are similar in children and adults, supporting continuity of the disorder's pathophysiology.

Mapping social reward and punishment processing in the human brain: A voxel-based meta-analysis of neuroimaging findings using the Social Incentive Delay task

This study maps brain regions involved in social reward and punishment processing using a voxel-based meta-analysis of fMRI data from the Social Incentive Delay task.

Are single peripheral measurements of baseline oxytocin in saliva and plasma reliable biomarkers of the physiology of the oxytocin system in humans?

This study assesses the reliability of single baseline salivary and plasma oxytocin measurements as biomarkers of the oxytocin system in humans, finding poor reliability and weak correlation between saliva and plasma oxytocin.

Investigating resting brain perfusion abnormalities and target-engagement by intranasal oxytocin in women with bulimia nervosa and binge-eating disorder and healthy controls

This study examines resting brain perfusion differences in women with bulimia nervosa/binge-eating disorder and healthy controls, and evaluates if intranasal oxytocin normalizes perfusion in affected brain circuits.

Effects of route of administration on oxytocin-induced changes in regional cerebral blood flow in humans

This study compares intranasal and intravenous oxytocin administration effects on regional cerebral blood flow, showing systemic OT increases drive amygdala perfusion changes and validating intranasal targeting of specific brain regions.

Embodied precision: Intranasal oxytocin modulates multisensory integration

This study investigates how intranasal oxytocin affects multisensory integration in bodily illusions, finding it enhances ownership in the rubber hand illusion and alters the size-weight illusion.
