Researchers from the University of Rochester, Brown University, and the University of Copenhagen used physics-informed AI together with MRI to estimate flow velocities in the brain's glymphatic system, according to a University of Rochester press release and coverage in Futurity and MedicalXpress. Their study, published in Science Advances, reconstructed fluid velocities from time-series MRI of dye spreading in brain tissue and animal experiments. The team reports two distinct transport regimes:
