This study maps serotonergic dynamics using drug-modulated molecular connectivity to show changes in serotonin transporter occupancy and functional brain network after MDMA exposure.

This study examines the relationship between BOLD-fMRI and EEG signals in the resting human brain, finding frequency- and network-specific time-lags and correlations.

This study uses PET/fMRI in rats to show MDMA causes global hemodynamic decreases and localized metabolic increases, indicating neurovascular uncoupling due to serotonin transporter occupancy.

The paper examines the relationship between dopamine D2 receptor and serotonin transporter availabilities in rats and their correlation with resting-state functional connectivity networks.

The paper analyzes longitudinal FDG-PET data to identify interregional causal influences of aging on brain metabolic activity, revealing how aging spreads across brain regions.
