Estimates for the astrocyte endfoot sheath permeability of the extra-cellular pathway

The paper estimates permeability parameters of astrocyte endfoot sheaths in mouse brain cortex for diffusive and advective transport.

Are brain displacements and pressures within the parenchyma induced by surface pressure differences? A computational modelling study

This study models brain parenchyma as elastic or poroelastic to assess if surface pressure differences drive intracranial fluid flow, finding they do not propagate through the parenchyma.

Human intracranial pulsatility during the cardiac cycle: a computational modelling framework

This paper develops a computational model of intracranial dynamics to simulate brain pulsatility during the cardiac cycle and validates it against clinical indicators.

Brain solute transport is more rapid in periarterial than perivenous spaces

The paper compares fluid flow and solute transport in periarterial and perivenous brain spaces using computational modeling, finding faster transport in periarterial spaces due to geometric differences.

The mechanisms behind perivascular fluid flow

This study uses computational fluid dynamics to show that arterial wall expansion, rigid motions, and a small static CSF pressure gradient generate net and oscillatory perivascular fluid flow, matching experimental observations.

Intracranial pressure elevation alters CSF clearance pathways

This study examines how intracranial pressure affects CSF clearance pathways using a mathematical model, finding that arachnoid granulations dominate outflow under elevated pressure.
