The last fifty years have seen substantial advances in an understanding of how the hippocampus works at the cellular level. Has our instruction to students about hippocampal anatomy kept pace with that progress? In this monograph, Miyawaki offers an approach to teaching the hippocampus informed by basic research in the last half century. The reader will be exposed to these topics: the relationship between dentate gyrus and the Cornu Ammonis, comparative vertebrate anatomy of the medial brain, James Papez's legacy, an introduction to place and grid cells, long-term potentiation (the original report), and redundancy in hippocampal wiring.
