This paper measures blood velocity response timing across the vascular network using dynamic PC-fMRA, showing arterial and venous responses with distinct temporal delays.

This paper develops a biophysical model to simulate fMRI responses in mice and humans, revealing species-specific hemodynamic differences and conserved vascular asymmetries.

This paper compares eight BOLD fMRI simulation approaches, finding that most are accurate but some are biased, with intravascular signal differences affecting results.

This study uses 7 Tesla fMRI to examine BOLD responses in newborns and adults, showing depth-dependent changes in cortical activity related to development.

This study introduces a new fMRA method to measure dynamic blood velocity responses in human posterior cerebral arteries during visual stimulation, showing a 10% increase in velocity and indicating neurovascular coupling.

This study shows that incorrect baseline modeling in fPET-FDG can create false metabolic activity patterns, affecting GLM analyses.
