Abstract

The regional density of capillaries varies in the brain, some regions having more capillaries per unit weight, other regions having fewer. This arrangement is anatomical and does not reflect a functional coupling of flow, capillary permeability, or cerebral metabolic rate. The total number of capillaries in anyone region is a reflection of the normal average energy requirement of the region and of the fact that individual capillaries have similar properties (radius, length, permeability) in different regions. This observation does not address the question of how many capillaries actually are perfused at anyone time and how this number varies with the changing energy requirements of individual regions.
