Since the first edition of this book was published (Duvernoy 1988), considerable advances have been made. The new edition therefore includes current concepts about functions of the hippocampus and a study of its external and internal vas cularization. Head sections and magnetic resonance imaging (MRI) views have also been added to the previous atlas of sections. The book is divided into four sections, preceded by an introduction (Chap. 1) and a short comment on the material and methods (Chap. 2). The first section ( Chap. 3) deals briefly with the structure, functions, and connections of the hip pocampus. This is followed in Chap. 4 by a description of the anatomy of the hippocampus and its relations with adjacent structures. The next section ( Chap. 5) is concerned with the vascularization of the hippocampus, and the final sec tion ( Chap. 6) is devoted to sectional anatomy and MRI. This work has benefitted from the invaluable help of many of my colleagues. First of all, I would like to express my gratitude to the late Professor Roger War wiek, who helped me clarify the difficult description of hippocampal anatomy. This book would not have been possible without the excellent illustrations by J.L. Vannson, the helpful advice given by Professor J. Guyot, Dr. P.Y. Risold, and Dr. F. Cattin, and the contribution made by Mr. A.E. Cabanis. I would also like to thank the members of the Department of Anatomy in Besans;on: Professor G.
