This study shows that inhibiting hippocampal CA2 neurons disrupts prefrontal and thalamic connectivity and impairs social behavior.

This study investigates the long-term effects of subchronic PCP treatment on prefrontal circuits in mice, revealing alterations in cognitive performance, gamma oscillations, and synaptic connectivity associated with schizophrenia endophenotypes.

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 uses simultaneous fPET/fMRI to show that optogenetic stimulation suppresses nigrostriatal pathway activity through presynaptic autoinhibition, revealing a dissociation between BOLD signal depression and neuronal inactivity.

StandardRat improves functional connectivity specificity in rat brains through a standardized MRI protocol tested across 20 centers.

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.

This study combines CRISPR/Cas9 gene editing with in vivo imaging to explore the impact of VMAT2 gene disruption on brain function and connectivity in rats.

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.
