The Reeler mutation was so named because of the alterations in gait that characterize homozygous mice. Several decades after the description of the Reeler phenotype, the mutated protein was discovered and named Reelin (Reln). Reln controls a number of fundamental steps in embryonic and postnatal brain development. A prominent embryonic function is the control of radial neuronal migration. As a consequence, homozygous Reeler mutants show disrupted cell layering in cortical brain structures. Reln also promotes postnatal neuronal maturation. Heterozygous mutants exhibit defects in dendrite extension and synapse formation, correlating with behavioral and cognitive deficits that are detectable at adult ages. The Reln-encoding gene is highly conserved between mice and humans. In humans, homozygous RELN mutations cause lissencephaly with cerebellar hypoplasia, a severe neuronal migration disorder that is reminiscent of the Reeler phenotype. In addition, RELN deficiency or dysfunction is also correlated with psychiatric and cognitive disorders, such as schizophrenia, bipolar disorder and autism, as well as some forms of epilepsy and Alzheimer's disease. Despite the wealth of anatomical studies of the Reeler mouse brain, and the molecular dissection of Reln signaling mechanisms, the consequences of Reln deficiency on the development and function of the human brain are not yet completely understood. This Research Topic include reviews that summarize our current knowledge of the molecular aspects of Reln function, original articles that advance our understanding of its expression and function in different brain regions, and reviews that critically assess the potential role of Reln in human psychiatric and cognitive disorders.

In recent years, medical developments have resulted in an increase in human life expectancy. Some developed countries now have a larger population of individuals aged over 64 than those under 14. One consequence of the ageing population is a higher incidence of certain neurodegenerative disorders. In order to prevent these, we need to learn more about them. This book provides up-to-date information on the use of transgenic mouse models in the study of neurodegenerative disorders such as Alzheimer's and Huntington's disease. By reproducing some of the pathological aspects of the diseases, these studies could reveal the mechanism for their onset or development. Some of the transgenic mice can also be used as targets for testing new compounds with the potential to prevent or combat these disorders. The editors have extensive knowledge and experience in this field and the book is aimed at undergraduates, postgraduates and academics. The chapters cover disorders including: Alzheimer's disease, Parkinson's disease, Huntington's and other CAG diseases, amyotrophic lateral sclerosis (ALS), recessive ataxias, disease caused by prions, and ischemia.

Animal disease models are a vital tool to study diseases and associated conditions. Studies on animal models can, in some cases, be used as a basis for modeling and understanding human diseases. Biomedical scientists face a challenge to choose the correct animal model to study disease pathology, and neurological diseases are no exception to this rule. Animal Models for Neurological Disorders covers different animal models which have been used for studying neurological disorders. 13 topical chapters have been contributed by a group of experts on the subject with an aim to cover emerging experimental models of a range of neurological diseases encountered in the clinic including Alzheimer’s disease, psychosis, Parkinson’s, Huntington’s disease, vascular dementia, schizophrenia, multiple sclerosis and brain tumors, among others. The chapters also inform readers about relevant clinical correlations in each disease model where appropriate. Animal Models for Neurological Disorders is intended for all scholarly researchers and students of biomedical sciences, pharmacology, medicine (oncology, neurology, psychiatry), pharmacy, biochemistry, and biotechnology. The organized contents of the book also serve as a quick reference point for scientists working in applied areas of neuroscience including the study of neurodegenerative diseases and cognitive dysfunction in living organisms.

Gamma-aminobutyric acid (GABA) was discovered in the brain in 1950 by Eugene Roberts. GABA is now considered one of the most important neurotransmitters and developmental signals. Knowledge on the complexity of GABA function is increasing exponentially. This volume covers basic research on GABA in the developing brain as it may relate to onset of autism and related developmental disorders. The evidence that dysfunction of GABA and related molecules is associated with autism is limited but expanding and seems to converge. Pertinent data are reviewed in this book and new research avenues in the basic and clinical arenas are described. The topics are of imminent interest to basic and clinical researchers as well as interested clinicians. * Discusses the neuropathology of the GABA system in autism * Presents new findings on common genetic mechanisms in Rett syndrome, Angelman syndrome, and autism * Includes information on the shared genetic risk factors between autism and major mental disorders * Foreword by Eugene Roberts

Only five years ago, nobody in his right mind would have consid ered publishing a book on reeler as a model for brain develop ment. Although this interesting mutation has been with us for half a century, it is fair to say that, in spite of a wave of enthusiasm in the late sixties and early seventies, generated primarily by Sidman, Caviness and colleagues, studies of reeler mice fell pro gressively out of fashion during the next two decades. All that changed almost overnight when the cloning of the reeler gene, dubbed reelin, was reported in Tom Curran's laboratory in 1995. The fact that the same gene was identified at the same time independently by two other groups using positional cloning sug gested strongly that reelin was the right candidate. Although the key experiments of transgenic rescue have not been made (and perhaps will never be), the equation "reeler is reelin" has been established beyond reasonable doubt, as alterations of the reelin gene and/or its expression have been found in at least five alleles of reeler and in the mutation Shaking Rat Kawasaki (SRK), an ortholog of reeler.

Developing novel and more effective treatments that improve quality of life for individuals with autism spectrum disorders is urgently needed. To date a wide range of behavioral interventions have been shown to be safe and effective for improving language and cognition and adaptive behavior in children and adolescents with ASD. However many people with ASD can receive additional benefit from targeted pharmacological interventions. One of the major drawback in setting up therapeutics intervention is the remarkable individual differences found across individuals with ASD. As a matter of fact the medications that are currently available address only symptoms associated with ASD and not the core domains of social and communication dysfunction. The pathogenesis paradigm shift of ASD towards synaptic abnormalities moved the research to pathway to disease that involve multiple systems and that are becoming the forefront of ASD treatment and are pointing toward the development of new targeted treatments. Some new therapeutics have been tested and others are being studied. In this context single gene disorders frequently associated with ASD such as Rett Syndrome, Fragile X and Tuberous Sclerosis have been of significant aid as neurobiology of these disorders is more clear and has a potential to shed light on the altered signaling in ASD. However much research is needed to further understand the basic mechanisms of disease and the relationship to idiopathic ASD. Clinical trials in children are underway with agents directed to core symptoms and to the associated disorders in the search of new therapeutics and progress are expected with possible new option for therapeutics in ASD in the upcoming future. Children and Adolescents with ASD and their families can provide important information about their experience with new treatments and this should be a priority for future research. In addition, research performed on genetic mouse models of ASD will keep on providing useful information on the molecular pathways dysrupted in the disease, thus contributing to identify novel drug targets.

The genetic, molecular, and cellular mechanisms of neural development are essential for understanding evolution and disorders of neural systems. Recent advances in genetic, molecular, and cell biological methods have generated a massive increase in new information, but there is a paucity of comprehensive and up-to-date syntheses, references, and historical perspectives on this important subject. The Comprehensive Developmental Neuroscience series is designed to fill this gap, offering the most thorough coverage of this field on the market today and addressing all aspects of how the nervous system and its components develop. Particular attention is paid to the effects of abnormal development and on new psychiatric/neurological treatments being developed based on our increased understanding of developmental mechanisms. Each volume in the series consists of review style articles that average 15-20pp and feature numerous illustrations and full references. Volume 2 offers 56 high level articles devoted mainly to Formation of Axons and Dendrites, Migration, Synaptogenesis, Developmental Sequences in the Maturation of Intrinsic and Synapse Driven Patterns. - Series offers 144 articles for 2904 full color pages addressing ways in which the nervous system and its components develop - Features leading experts in various subfields as Section Editors and article Authors - All articles peer reviewed by Section Editors to ensure accuracy, thoroughness, and scholarship - Volume 2 sections include coverage of mechanisms which regulate: the formation of axons and dendrites, cell migration, synapse formation and maintenance during development, and neural activity, from cell-intrinsic maturation to early correlated patterns of activity

Animal models of neuro- and psychopathological states in humans are an indispensable part of both experimental neurology and biological psychiatry. Written by a team of experts, this book provides an up-to-date detailed overview of the current approaches to the design of viable animal models for eight prominent neuropsychiatric diseases. The book is specifically written with the research-oriented reader in mind — both in academia and the pharmaceutical industry. It contains first-hand information on how to design viable animal models for Alzheimer's disease, epilepsy, Huntington's disease, Parkinson's disease, addiction, depression, fear and anxiety, and schizophrenia. Each chapter also critically discusses the limitations of the animal experimental approach towards an understanding of human neuropsychiatric disorders.The book is an essential source of reference for researchers who seek to successfully continue and elaborate the experimental work that will finally lead to a better understanding of the neurobiological basis of the diseases, as well as to an improvement of both diagnosis and therapy.
