This book was released on 2005 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malformations of cortical development are frequently associated with severe neurological disorders such as autism, mental retardation, and pediatric cases of intractable epilepsy. Current studies have focused on understanding mechanisms underlying epileptogenesis in these conditions. However, a more general and far-reaching question of how a malformed brain develops remains unanswered. The overall aim of this dissertation was to characterize defects in cortical development that occur in the teratogen-induced model of cortical dysplasia i.e., prenatal methylazoxymethanol (MAM) exposure in the rat. The results established that nodular heterotopias in the hippocampus of MAM-exposed rats arise early in the postnatal period, following a loss of cell adhesion and increased cell death at the cortico-hippocampal junction. In the embryonic brain, we observed a break down of the radial glial scaffold and disruption of prenatal architecture (including elements such as the cortical plate and ventricular zone). In addition, the marginal zone, an already established region, appeared disorganized. The unexpected disorganization of the marginal zone could result from an acute loss of stromal-derived factor-1 (SDF-1). Our results demonstrated that SDF-1 was sufficient and necessary for reelin-(+) cells to localize to the meningeal surface in the MAM brain in vitro . This finding revealed that a global insult (i.e., teratogen exposure) can result in a specific alteration of a soluble factor critical to neurodevelopment (i.e., decreased SDF-1 in the meninges). The normal marginal zone also required SDF-1 for structural maintenance since blocking SDF-1 activity in vitro and in vivo resulted in marginal zone disorganization. From these anatomical studies in MAM-exposed rats, we uncovered specific molecules and steps in the process of abnormal brain development. These findings, at least in some cases, are similar to what was observed in cortical dysplastic tissue obtained from patients with epilepsy e.g., a disruption of the superficial layer (MZ in the MAM-exposed brain and layer I tissue from FCD patients). This works supports the use of animal models to uncover fundamental mechanisms related to how a malformed brain develops. These findings in the MAM-exposed rat brain could provide insight into the processes taking place in patients with malformations of cortical development.

Download or read book Pediatric Neuroimaging written by A. James Barkovich and published by Lippincott Williams & Wilkins. This book was released on 2012-02-20 with total page 3865 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thoroughly updated Fifth Edition of Pediatric Neuroimaging is a highly illustrated text-reference that describes and illustrates the full range of pediatric disorders diagnosable by modern neuroimaging. Covering the diagnosis of brain, spinal, and head and neck disorders in the pediatric patient, the text is rooted in the principle that the proper interpretation of studies requires the acquisition of high-quality images and an understanding of the basic concepts of neuroembryology, normal development, and pathophysiology. Much coverage is given to the disorders seen in everyday practice. The emphasis is on CT and MRI, which are the optimal imaging modalities in children. The first two chapters describe useful imaging techniques in this patient population and the imaging manifestations of normal development, to distinguish that from manifestations of disease. The final ten chapters of the book are divided by groups of diseases, with numerous drawings and images that illuminate the underlying pathologic and embryologic/genetic bases of each disorder. The goal is provide a basic approach to groups of diseases, then offer detailed information about the clinical manifestations, underlying biochemistry, molecular biology, genetics and/or pathology of specific disorders. The book incorporates the essential concepts for obtaining good images and understanding normal development, which helps the reader to distinguish normal developmental changes from disease

Download or read book From Neurons to Neighborhoods written by National Research Council and published by National Academies Press. This book was released on 2000-11-13 with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: How we raise young children is one of today's most highly personalized and sharply politicized issues, in part because each of us can claim some level of "expertise." The debate has intensified as discoveries about our development-in the womb and in the first months and years-have reached the popular media. How can we use our burgeoning knowledge to assure the well-being of all young children, for their own sake as well as for the sake of our nation? Drawing from new findings, this book presents important conclusions about nature-versus-nurture, the impact of being born into a working family, the effect of politics on programs for children, the costs and benefits of intervention, and other issues. The committee issues a series of challenges to decision makers regarding the quality of child care, issues of racial and ethnic diversity, the integration of children's cognitive and emotional development, and more. Authoritative yet accessible, From Neurons to Neighborhoods presents the evidence about "brain wiring" and how kids learn to speak, think, and regulate their behavior. It examines the effect of the climate-family, child care, community-within which the child grows.

Book excerpt: "1 Clinical history, clinical correlations with placental pathology and prematurity The initial steps in the process of perinatal nervous system evaluation, namely the planning of the optimal approach and choice of samples to be obtained, are driven by the clinical context. Of key importance are the following data: a. Gestational age at time of demise (if stillborn); or gestational age and postnatal age (if liveborn), for comparison with normative standards of development (see Appendix); b. State of maternal health (age, parity, pre-existing medical conditions or ones appearing during gestation or around the time of delivery, exposure to medications/toxins/infections), and of health of siblings or other family members: - Concerns for inherited (i.e., genetic) conditions, metabolic disorders, congenital infections, etc., may indicate the need for special testing; c. Details of prenatal course, including any imaging, amniocentesis, or monitoring: - Prenatal imaging modalities most commonly consist of transabdominal ultrasonography, generally done at the time of the first prenatal visit (to confirm pregnancy) or more usually in the mid-second-trimester for detection of fetal or placental anomalies"--
