The paper uses low-rank tensor decompositions to analyze glymphatic MRI data and identifies spatiotemporal patterns of CSF tracer transport in the human brain, revealing differences between iNPH and reference cohorts.

This study predicts tracer distribution in the brain using geometric MRI data, showing strong correlation with actual tracer enrichment in patients with similar diagnoses.

This study shows that sleep deprivation reduces brain clearance rates but preserves their spatial pattern, affecting tau propagation differently in a computational model.

The paper quantifies human brain solute transport mechanisms using MRI data and computational modeling, showing that enhanced extracellular diffusion and advection are key during sleep.

The paper models CSF circulation to show that convection in the subarachnoid space rapidly clears tracers from intracranial compartments, reducing clearance time from years to days compared to diffusion.
