Possibility of linear dependence between vascular wall tension and blood flow in precortical arterioles.
Intravital microscopy was used to determine the diameter and length of pial cortical arterioles in rat brain. Mathematical model yielded a formula showing that regulation of arteriolar wall tension results in autoregulation of the blood flow.
