Book Description
During evolution the vertebrate head has acquired a number of unique features including specialized paired sense organs and cranial sensory ganglia. These evolutionary novelties arise from discrete thickenings of the head ectoderm known as cranial placodes. They include the adenohypophyseal, olfactory, lens, trigeminal, profundal, otic, epibranchial and lateral line placodes. While distinct in the derivatives and cell types they will form, all cranial placodes originate from a common preplacodal domain surrounding the anterior neural plate. Recent evidence suggests that the induction of this pre-placodal domain and its subsequent subdivision into individual placodes with specific identities is a multi-step process. Here we describe the development of these placodes and their derivatives and summarize recent advances in the characterization of the repertoire of transcription factors underlying their development. We also review recent studies that have started to address the role of several classes of signaling molecules in placode induction and segregation, including Bone Morphogenetic Proteins, Fibroblast Growth Factors and Wnt molecules.

Book Description
Although evolutionary developmental biology is a new field, its origins lie in the last century; the search for connections between embryonic development (ontogeny) and evolutionary change (phylogeny) has been a long one. Evolutionary developmental biology is however more than just a fusion of the fields of developmental and evolutionary biology. It forges a unification of genomic, developmental, organismal, population and natural selection approaches to evolutionary change. It is concerned with how developmental processes evolve; how evolution produces novel structures, functions and behaviours; and how development, evolution and ecology are integrated to bring about and stabilize evolutionary change. The previous edition of this title, published in 1992, defined the terms and laid out the field for evolutionary developmental biology. This field is now one of the most active and fast growing within biology and this is reflected in this second edition, which is more than twice the length of the original and brought completely up to date. There are new chapters on major transitions in animal evolution, expanded coverage of comparative embryonic development and the inclusion of recent advances in genetics and molecular biology. The book is divided into eight parts which: place evolutionary developmental biology in the historical context of the search for relationships between development and evolution; detail the historical background leading to evolutionary embryology; explore embryos in development and embryos in evolution; discuss the relationship between embryos, evolution, environment and ecology; discuss the dilemma for homology of the fact that development evolves; deal with the importance of understanding how embryos measure time and place both through development and evolutionarily through heterochrony and heterotrophy; and set out the principles and processes that underlie evolutionary developmental biology. With over one hundred illustrations and photographs, extensive cross-referencing between chapters and boxes for ancillary material, this latest edition will be of immense interest to graduate and advanced undergraduate students in cell, developmental and molecular biology, and in zoology, evolution, ecology and entomology; in fact anyone with an interest in this new and increasingly important and interdisciplinary field which unifies biology.

Book Description
This 1999 edition of The Neural Crest contains comprehensive information about the neural crest, a structure unique to the vertebrate embryo, which has only a transient existence in early embryonic life. The ontogeny of the neural crest embodies the most important issues in developmental biology, as the neural crest is considered to have played a crucial role in evolution of the vertebrate phylum. Data that analyse neural crest ontogeny in murine and zebrafish embryos have been included in this revision. This revised edition also takes advantage of recent advances in our understanding of markers of neural crest cell subpopulations, and a full chapter is now devoted to cell lineage analysis. The major research breakthrough since the first edition has been the introduction of molecular biology to neural crest research, enabling an elucidation of many molecular mechanisms of neural crest development. This book is essential reading for students and researchers in developmental biology, cell biology, and neuroscience.

Book Description
Fully updated and revised according to student feedback, the sixth edition of Mayo Clinic Medical Neurosciences: Organized by Neurologic System and Level provides a systematic approach to anatomy, physiology, and pathology of the nervous system inspired by the neurologist's approach to solving clinical problems. This volume has 4 sections: 1) an overview of the neurosciences necessary for understanding anatomical localization and pathophysiologic characterization of neurologic disorders; 2) an approach to localizing lesions in the 7 longitudinal systems of the nervous system; 3) an approach to localizing lesions in the 4 horizontal levels of the nervous system; and 4) a collection of clinical problems. This book provides the neuroscience framework to support the neurologist in a clinical setting and is also a great resource for neurology and psychiatry board certifications. This is the perfect guide for all medical students and neurology, psychiatry, and physical medicine residents at early stages of training. New to This Edition - A chapter devoted to multiple-choice questions for self-assessment - Discussion of emerging concepts in molecular, cellular, and system neurosciences - New chapters on emotion and consciousness systems - Incorporation of new discoveries in neuroimaging and an appendix for tables of medications commonly used to treat neurologic disorders

Book Description
Evolutionary Developmental Biology, Volume 141 focuses on recent research in evolutionary developmental biology, the science studying how changes in development cause the variations that natural selection operate on. Several new hypotheses and models are presented in this volume, and these concern how homology may be properly delineated, how neural crest and placode cells emerged and how they formed the skull and jaw, and how plasticity and developmental symbiosis enable normal development to be regulated by environmental factors. - New models for homology - New hypotheses for the generation of chordates - New models for the roles of plasticity and symbionts in normal development

Book Description
This book documents the state of the art in pediatric neurosurgery with the intention of providing a comprehensive guide to the management of the full range of pediatric neurosurgical disorders that will aid in the delivery of optimal care. Detailed practical instruction, taking into account recent advances, is provided on the neurosurgical treatment of congenital brain malformations, cerebrovascular diseases, head injuries and spinal trauma, infections, functional disorders, congenital and developmental spinal disorders, and brain and spinal tumors. Pearls and pitfalls are highlighted, and attention drawn to the most useful tips and tricks. Information is also included on relevant related topics, including the principles of neuroimaging, the physiological responses of newborns, infants, and children to neurosurgical trauma, preoperative evaluation, anesthesiology and intensive care, and other forms of therapy. The authors are renowned experts in the field, and the text is supported by a wealth of high-quality images. Handbook of Pediatric Neurosurgery will be of value for neurosurgeons of all levels of experience, as well as for pediatricians, neuroradiologists, neuropathologists, and neuro-oncologists.
