Upstream current for a downstream flow

Nature Neuroscience 20, 631 (2017). doi:10.1038/nn.4542 Author: Jessica A Filosa Capillary endothelial cells sense neuronal activity-evoked increases in extracellular K+ via KIR2.1 inwardly rectifying K+ channels. The ensuing hyperpolarization travels upstream along the vascular network, reaching arterioles and evoking vasodilation.
