About this book

This book deals with problems and approaches to cellular systems and will cover a wide range of cell types and cell systems, including nerve cells. It will be of interest to cell biologists interested in modeling, and to any students interested in the field. It will also appeal to the theoretical and mathematical biology community, and would have relevance to individuals interested in evolutionary issues as they bear on cellular metabolic models. It will be a solid theoretical book, with an empirical base and an evolution connection, that fits exactly to the initial theme of the theoretical biology series.
