Morphology of the nervous system of Polychaeta (Annelida)
The article summarizes the up to date knowledge about the morphology of the annelid, especially the polychaete, central and peripheral nervous system, and the structure of its neuropile, associated ganglia and nerves is reviewed in detail.

Immunohistochemical investigations in Annelida enable more detailed reanalyses of known structures and detection of new characteristics that are useful for phylogenetic analyses and it is shown that hitherto unknown nerves are present in the peripheral nervous system.
Neuroarchitecture of the lower division of the central body in the brain of the locust (Schistocerca gregaria)
The anatomical organization of the lower division of the central body in the brain of the locust Schistocerca gregaria is investigated and possible functional implications for the processing of neuronal information in the central complex are discussed.
Neurons of the Central Complex of the Locust Schistocerca gregaria are Sensitive to Polarized Light
It is reported that particular types of central complex interneurons are sensitive to polarized light, and these neurons might serve a function in sky compass-mediated spatial navigation of the animals.
Musculature and nervous system of Gnathostomula peregrina (Gnathostomulida) shown by phalloidin labeling, immunohistochemistry, and cLSM, and their phylogenetic significance
The results reveal the musculature and nervous system of Gnathostomula to be more complex than hitherto reported.

The high conservation in the pattern of GABA immunostaining in all insect species investigated so far suggests that GABA plays an essential role in the basic neural circuitry of the central complex in insects.
Experiments on anterior regeneration in Eurythoe complanata ("Polychaeta", Amphinomidae): reconfiguration of the nervous system and its function for regeneration
It is demonstrated that the nervous system is essential for regeneration: it induces cell proliferation in the blastema and subsequently in the regenerate.
Reconstruction of the muscle system in Antygomonas sp. (Kinorhyncha, Cyclorhagida) by means of phalloidin labeling and cLSM
The entire muscle system of the cyclorhagid kinorhynch Antygomonas sp.
CLSM analysis of the phalloidin‐stained muscle system in Nerilla antennata, Nerillidium sp. and Trochonerilla mobilis (Polychaeta; Nerillidae)
The results support the belief that absence of circular muscles in the polychaete body wall is much more widely distributed than is currently presumed.
Comparative analysis of the nervous systems in presumptive progenetic dinophilid and dorvilleid polychaetes (Annelida) by immunohistochemistry and cLSM
The Dinophilus nervous system with 12 longitudinal nerves and three perpendicular nerve rings per segment resembles orthogonal nervous structures characteristic of platyhelminths, and this result cannot support the view that dinophilids originate from dorvilleids.
