The most recent research findings on the important genes, key molecules, and mechanisms in neural development and regeneration are presented in this volume. The papers collected here were delivered at the second of the Keio University International Symposia for Life Sciences and Medicine, held in Mita (Tokyo), Japan, and are in eight main sections: Early Neurogenesis and Pattern Formation, Regional and Cellular Specification, Trophic Factors, Adhesion Molecules, Glial Cell Lineage and Myelination, Circuit Formation, Synaptic Refinement and Neurotransmitter Release, and Neural Regeneration. Together, they present the concept of neural development and regeneration and its vital importance at the frontiers of medical science today. Neural Development is an invaluable resource and reference for researchers, clinicians, and students in physiology and the medical sciences.
