Influence of tracer solute diffusion coefficient on solute movement in brain ECS. (A) Pseudocolored images showing tracer solute accumulation in ECS, as in Fig 3, for the indicated tracer solute diffusion coefficients, D, and for ΔP = 1 mmHg. Parameters: Pf = 0.04 cm/s and α = 0.2. (B) Kinetics of tracer solute accumulation in ECS for the indicated D and ΔP.
