Figure 2.

(A) The en face MIP of the 3D angiogram with color indicating the depth from the cortical surface. Bar=100 μm. (B, C, D) Estimated RBC speed, flux, and density are presented as color spots on the MIP angiogram. We used relatively comparable ranges (median±40%) for all quantities. (E) Histograms (top) and depth profiles (bottom) of the RBC speed, flux, and density measured from three animals (n=2,259 measures in total). Comparable histogram ranges (median±40%) are used. In the depth profiles, data are presented as mean±s.d. (F) Correlations between the flux vs. the speed and density (n=2,259). Dashed lines indicate median±40% of the density (left) and speed (right).
