The paper investigates how spatial collinearity among PET receptor maps affects multivariate molecular-enriched network estimation and finds that univariate modelling is more reliable.

This study links human brain functional connectivity to neurotransmitter systems using resting-state fMRI and MEG across multiple cohorts, showing consistent patterns and clinical relevance.

This systematic review examines the effects of psychedelics on associative learning in humans and animals, finding enhanced learning in animals but inconsistent results and methodological heterogeneity.

The paper identifies two reproducible reward imaging phenotypes linked to dopamine D2 receptor function and shows differential responses to antipsychotic drugs.

This study investigates how dopamine D2/D3 antagonism affects mental state inference and self-relevance of social outcomes using a game-theoretic paradigm and computational model.

This paper extends the REACT method to ASL fMRI, showing it can detect molecular-enriched functional connectivity comparable to BOLD fMRI, with complementary information.

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.

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.

This study shows that dopamine manipulation affects social inferences related to paranoia in healthy individuals, with haloperidol reducing harmful intent attributions and L-DOPA having context-dependent effects.

This study uses REACT to analyze how methylphenidate affects dopaminergic and noradrenergic circuits in the brain and links these effects to behavioral responses in a reinforcement-learning task.

JuSpace links MRI-based functional activity with neurotransmitter systems using cross-modal correlation, finding significant associations in Parkinson's disease and risperidone effects.

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.

This study investigates the effect of combined haloperidol and levodopa on working memory-related brain activation in humans, finding reduced activity in occipital/temporal areas and increased salience network connectivity.

The paper investigates how cerebral blood flow changes in response to drugs targeting different neurotransmitter systems and finds a reliable spatial link between blood flow changes and receptor densities.
