watershed zone

a zone that lies between the vascular distribution areas (vascular beds) of two arteries. Although the cerebral cortex is well supplied by arteries with collateral branches, there are areas at the junction of the parietal and occipital lobes and between the parietal and temporal lobes that are watershed zones. Such areas are particularly sensitive to anoxic injury (see watershed infarction).
