This study identifies structural brain deviations in post-COVID-19 patients using normative modelling and network analysis, linking them to TMPRSS2 expression and neural circuit disruptions.

This study uses multimodal MRI to find altered brain perfusion and oxygen metabolism in PCS, linked to cognitive and emotional symptoms.

This study examines how anhedonia severity affects attentional network recruitment and emotional blunting during music listening in healthy adults.

The paper identifies cellular and neurochemical signatures associated with cerebral blood flow alterations in schizophrenia and clinical high-risk states using combined neuroimaging and transcriptomic data.

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 investigates the effects of acute Methylene Blue administration on cerebral blood flow and metabolism in humans and rats, finding dose-dependent reductions in CBF and metabolic rates contrary to initial hypotheses.

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.

ExploreASL provides a standardized image processing pipeline for multi-center ASL MRI studies, improving reproducibility and enabling group-level statistical analysis across diverse clinical populations.

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.

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.

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.
