Some SPR-LI neurons were also positive for TH. After administration of vasopressin, SPR-LI structures became denser, especially at levels of pyramidal decussation and area postrema . The dendrites of motor dorsal nucleus of X in the dorsal part of MVZ appeared thin and straight in morphology instead of curl and thick outlooks. These results implicate that some SPR-LI neurons might receive or regulate the cardiovascular stress information induced by vasopressin.③In PHA-L/FOS/TH triple-labeled experiments, seven kinds of immunohistochemical structures were found in MVZ. They were FOS-LI neurons, TH-LI neurons, PHA-L positive fibers, PHA-L positive fibers terminated on FOS-LI or TH-LI neurons, FOS/TH doublelabeled neurons, PHA-L positive fibers terminated on FOS/TH double-labeled neurons.
