| Abstract: | Summary The hypothalamic magnocellular preoptic nucleus of Rana temporaria was studied at the electron-microscopic level with the use of the unlabeled antibody peroxidase-antiperoxidase complex (PAP) technique. The magnocellular preoptic nucleus of R. temporaria contains at least three different types of neurons: (1) Vasotocinergic neurons, (2) mesotocinergic neurons, and (3) neurons that contain either somatostatin or an immunologically related peptide. The present results are in complete agreement with those of previous immunocytochemical studies conducted at the light microscopic level. |
