[Ultrastructure of neurons of nucleus preopticus and pars lateralis of the nucleus lateralis tuberis in Gambusia (Teleosta poeciliidae)].
The nucleus preopticus (NPO) and the pars lateralis of the nucleus lateralis tuberis (NLT) have been examined at the ultrastructural level. In the NPO two types of large neurons occur, both containing 140-150 nm secretory granules. The pars lateralis of the NLT contains only one cell type with similar granules. Both of these nuclei may be the source of type A fibres innervating the gonadotropic cells of Gambusia.
