Variation in hydraulic resistance. A Hydraulic resistance and area of the perivascular space for the segmentation at each cross-section. Measurements from upstream and downstream locations are specified with up and down arrows respectively, and measurements from the same mouse are plotted with similar colors (see Table 1). The hydraulic resistance approximately scales with PVS area. B The distributions of hydraulic resistance per unit length across all cross sections from all vessels based on the original segmented regions and the various fits. The spline fit is plotted separately (lower inset) because its resistance is larger than the other fits. C, Upper inset Share of segmented cross sections whose hydraulic resistances are best predicted by each model. The polynomial fit distribution most closely matches that of the segmentation, and the polynomial fit was the best match for the majority of cross sections
