Table 2.

The four different parametric scenarios tested in this article

	κpar = 1.2 × 10−17 m2	κpar = 4.5 × 10−15 m2
	g = 20 nm	g = 5.1 μm
κPVS = 4.5 × 10−15 m2 Γpen = 0.36	Rmax	Intermediate 2
Open penetrating and precapillary PVSs Γpen = 1.4	Intermediate 1	Rmin

These four scenarios result from bracketing uncertain parameters related to: (left column) PVS permeability and penetrating PVS size and (top row) parenchymal permeability and astrocyte endfoot gap size
