[Nontraditional "large-cell" neuroendocrine formations (accessory nuclei) in the brain of Anamnia and Amniota].
Using immunochemical PAP-method nonapeptidergic neuroendocrine formations in the hypothalamus and adjacent brain areas of fishes (the sterlet Acipenser ruthenus, the shark Scylliorhinus canicula), amphibians (the frog Rana temporaria), reptiles (the snake Natrix natrix), mammals (rats and dogs) and human have been studied. In Amniota and human accessory nuclei (AN) in addition to main "magnocellular" nuclei (supraoptic, postoptic and paraventricular) were discovered. Two AN, circular and dorsolateral ones, were found in snakes, and circular, dorsolateral, forniceal and extrahypothalamic AN were revealed in rat, dog and human brain. In Anamnia, sharks and frogs, in contrast to sterlets, the dorsolateral sub-nucleus inside preoptic nucleus was identified. AN similarity in the phylogenetic row of vertebrates and mechanisms of AN creation in phylo- and ontogenesis were discussed.
