Arteriole-venule arrangement may influence cortical perfusion efficiency; modeling leaves open translation to human cerebrovascular disorders.
Mathematical modeling reveals that the optimal arteriole-venule ratio in the cerebral cortex is determined by the need to balance the size and number of low-flow regions, matching observed mammalian vascular anatomy.
