5-Hydroxytryptamine (serotonin)-containing neurons in the rat's medullary raphe and interfascicularis hypoglossi cell groups were identified by means of autoradiography following prolonged intraventricular administration of 5-hydroxy[(3)H]tryptamine, fluorescence histochemistry for the demonstration of endogenous 5-hydroxytryptamine, and microspectrofluorimetric analysis of excitation and emission spectra. Immunocytochemical methods (the unlabeled primary antibody-peroxidase antiperoxidase and… CONTINUE READING
