AbstractThis study is the third part of a comprehensive series of publications on the cytoarchitectonic organization of the brain of the European sea bass, Dicentrarchus labrax. This study provides an atlas of the brain stem based on Nissl-stained transverse sections as well as a description of cell masses and a discussion on comparative aspects of brain stem nuclei, including methodological studies in other species. By external examination, the sea bass exhibits a prominent Optic tectum and Corpus cerebelli as expected in a predator species with a highly developed visual system. However, no hypertrophy of the facial and vagal lobes was observed as reported in other non-perciform teleosts. The general organization pattern of the mesencephalon and rhombencephalon of the sea bass brain resembles that reported for other perciform teleosts. However, the Valvula cerebelli has been subdivided into anterior, central and posterior parts. In addition, the ventricular surface of the granular layer of the Valvula cerebelli appears to be in contact with those of the Torus longitudinalis. This cell apposition could be interpreted as a direct connection, but more studies demonstrating the absence of ependyma between both structures are needed. Furthermore, we have tentatively described the electro/mechano receptive pre-eminential nucleus in the rhombencephalon of the sea bass. This study completes one of the few descriptions, as well as the most complete and detailed available, of the brain of any marine perciform species. © 2008 Elsevier GmbH. All rights reserved.
