Abstract
An intravital microscopic study of pial microvasculature in the rat cerebral cortex showed that, both in the resting state and when the vessels are dilated as a result of ischemia, the principle of minimal energy expenditure is one of the factors regulating the ratio of arteriolar diameters in arteriolar ramifications.
