  • Title: Immunofluorescence analysis of the internal brain anatomy of Nereis diversicolor (Polychaeta, Annelida).
    Author: Heuer CM, Loesel R.
    Journal: Cell Tissue Res; 2008 Mar; 331(3):713-24. PubMed ID: 18071754.
    Abstract:
    Comparative analyses of neuroanatomical characters can make valuable contributions to the inference of phylogenetic relationships. Whereas investigations in this field are numerous for arthropods, in-depth studies on other protostomes are sparse. Here, we provide a survey of the internal neuroarchitecture of the brain of the aciculate ragworm Nereis diversicolor (Polychaeta, Annelida). Descriptions are based on confocal laser scanning microscope analyses of brain sections labeled with the nuclear marker DAPI and antibodies raised against FMRF-amide, serotonin, and histamine. Autofluorescence of the nervous tissue has been utilized to further elucidate the anatomical structures of the brain. The architecture of two major brain compartments, i.e., the paired mushroom bodies and the central optic neuropil, is described in detail. The findings are compared with existent literature on polychaete neuroanatomy and on arthropod neuroanatomy, and possible phylogenetic implications are outlined.
