Forebrain evolution in fishes

Much of the remarkable progress made recently in the understanding of forebrain organization and evolution in fishes is due to new molecular markers revealing new insights into forebrain development and organization, which is reflected in this publication. The authors present papers covering research of all major groups of fishes. Topics include the segmental organization of the forebrain in lampreys, new perspectives on the organization of the telecephalon in elasmobranchs, and an evolutionary interpretation of teleostean forebrain molecular anatomy. Further papers deal with an immunohistochemical approach to lungfish forebrain organization and with the comparisons of forebrain organization in the basal ray-finned fishes and the teleosts, and finally, the structural organization of the forebrain in fishes is summarized. The papers in this publication are based on the 20th Annual Karger Workshop held in Washington, D. C., in 2008, which was conceived to honor Professor Rudolf Nieuwenhuys, who celebrated his 80th birthday and who is the most eminent living comparative neurobiologist.
