Figure 7.

Laminar dependence and spatial localization of flow changes after simulated vessel dilation for various vessel categories: arterioles (superficial-deep; ASD), arterioles (superficial-intermediate; ASI), capillaries (superficial; CS), capillaries (intermediate; CI), capillaries (deep; CD), capillaries (connecting intermediate to deep; CC). (A) Proportionate change in the total flow among all capillaries in the three retinal layers, due to bulk dilation of a given vessel category; (B) response to a single 10% arteriolar dilation, as a function of branch order relative to the dilation site and averaged over all arteriolar dilation sites; (C) designation of branch order relative to dilation site. The dilated vessel in the illustrated case is an arteriole connecting the superficial and intermediate layers.
