Abstract
Confocal microscopy of fluo-4 fluorescence in pressurized rat mesenteric small arteries subjected to low-frequency electrical field stimulation revealed Ca2+ transients in perivascular nerves and novel, spatially localized Ca2+ transients in adjacent smooth muscle cells. These muscle Ca2+ transients occur with a very brief latency to the stimulus pulse (most
