Brain endothelial gap junction coupling enables rapid vasodilation propagation during neurovascular coupling Vasodilatory signals are rapidly communicated across long distances by endothelial-endothelial gap junctions, enabling coordinated dilation of the arterial network during neurovascular coupling.
