This book was released on 2010 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The postnatal development of the human hippocampal formation (HF) is subject of increasing interest due to its implication in important pathologies that hamper the normal development of children. In this work, the authors present a glimpse of the main events that constitute important milestones in the development and shaping of some of the most important psychological capabilities such as autobiographical memory. Although they examined some cases in the last trimester of gestation, their description starts at birth, around 40 gestational weeks. Serial sections with thionin for Nissl analysis revealed that all fields of the HF were present and identifiable at birth. However, the relative growth of the cortical mantle was much higher relative to the HF. The main structural changes took place during the first postnatal year, in particular in the dentate gyrus and in the entorhinal cortex. At subsequent ages, a growth in size was noted in all components of the HF. This growth was more evident at the body and tail of the hippocampus, as evidenced by measurements of the neuroanatomical series. In addition, the authors examined in some cases the MRI appearance of the HF at different postnatal ages obtained by post-mortem imaging. MRI neuroanatomical series provided anatomically identified landmarks useful for the MRI identification of different components of the HF during postnatal development.

Book excerpt: The hippocampal formation is a multicomponent region of the medial temporal lobe preferentially involved in declarative and relational memory processing. Behavioral studies have suggested a protracted functional maturation of these structures in primates, and postnatal developmental abnormalities in the hippocampal formation are thought to contribute to neurodevelopmental disorders, such as autism, schizophrenia, epilepsy and Down syndrome. Despite all that we know about the functional organization of the adult hippocampal formation, notably absent is a systematic study of its postnatal maturation in primates. In this article, we review current knowledge of the structural development of the primate hippocampal formation and present new data on its postnatal neuroanatomical development. We summarize what is known about the neurobiological processes, such as the addition of new neurons, the establishment and elaboration of connectivity, and the neurochemical changes, that underlie the structural development and functional maturation of the primate hippocampal formation. We conclude that there is yet insufficient information to identify distinct developmental windows during which different hippocampal regions undergo specific maturational processes. For this reason, it is currently impossible to determine the ages at which specific hippocampal circuits become structurally mature and potentially capable of supporting defined, age-specific functional processes. Together with work in rodents, systematic studies of the structural development and functional maturation of the monkey hippocampal formation will be necessary to gain insight not only into the types of information processing that it subserves, but also into the specific maturational processes that might be affected in human neurodevelopmental disorders.

Download or read book Hippocampal Development written by S. J. Pleasure and published by S. Karger AG (Switzerland). This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hippocampal formation plays a critical role in navigation and memory under normal conditions. In pathologies such as Alzheimer's disease and epilepsy, the hippocampus represents one of the first brain regions to suffer damage. When hippocampal development is abnormal, pathological conditions featuring cognitive dysfunction and seizures are common, particularly in children. This publication summarizes new data and relevant findings to a critical understanding of hippocampal development - from anatomy to physiology and from rodents to human. It provides original articles on developmental pathology and on the ongoing role of developmental signaling systems in adults. Broadly, the topics include processes involved in the development of normal or abnormal hippocampus and pathological implications associated with normal or abnormal development, and neurogenesis in an immature or adult hippocampus. Presenting a wide-ranging collection of contributions on hippocampal development, this issue will be of great value for neurobiologists, neurologists, psychiatrists and pediatricians.

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.
Download or read book SIDS Sudden Infant and Early Childhood Death written by Roger W. Byard and published by . This book was released on 2018-04 with total page 844 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume covers aspects of sudden infant and early childhood death, ranging from issues with parental grief, to the most recent theories of brainstem neurotransmitters. It also deals with the changes that have occurred over time with the definitions of SIDS (sudden infant death syndrome), SUDI (sudden unexpected death in infancy) and SUDIC (sudden unexpected death in childhood). The text will be indispensable for SIDS researchers, SIDS organisations, paediatric pathologists, forensic pathologists, paediatricians and families, in addition to residents in training programs that involve paediatrics. It will also be of use to other physicians, lawyers and law enforcement officials who deal with these cases, and should be a useful addition to all medical examiner/forensic, paediatric and pathology departments, hospital and university libraries on a global scale. Given the marked changes that have occurred in the epidemiology and understanding of SIDS and sudden death in the very young over the past decade, a text such as this is very timely and is also urgently needed.

Download or read book The Hippocampus Book written by Per Andersen and published by Oxford University Press. This book was released on 2007 with total page 892 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hippocampus is one of a group of remarkable structures embedded within the brain's medial temporal lobe. Long known to be important for memory, it has been a prime focus of neuroscience research for many years. The Hippocampus Book promises to facilitate developments in the field in a major way by bringing together, for the first time, contributions by leading international scientists knowledgeable about hippocampal anatomy, physiology, and function. This authoritative volume offers the most comprehensive, up-to-date account of what the hippocampus does, how it does it, and what happens when things go wrong. At the same time, it illustrates how research focusing on this single brain structure has revealed principles of wider generality for the whole brain in relation to anatomical connectivity, synaptic plasticity, cognition and behavior, and computational algorithms. Well-organized in its presentation of both theory and experimental data, this peerless work vividly illustrates the astonishing progress that has been made in unraveling the workings of the brain. The Hippocampus Book is destined to take a central place on every neuroscientist's bookshelf.
Download or read book The Parahippocampal Region written by Menno P. Witter and published by Oxford University Press, USA. This book was released on 2002 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent dramatic advances in imaging technologies have enabled researchers to build on the evidence obtained from lesion and behavioural studies to propose a new range of functions for the parahippocampal region. It is now possible to image the region in healthy human subjects and todefine the pathological changes occurring during the early phases of a range of neurologic and psychiatric conditions.The results have uncovered evidence suggesting that the region plays an important role in the higher cognitive processes of learning and memory, and in specific brain diseases, including Alzheimer's disease, schizophrenia and epilepsy, as well as in the aging process itself.The Parahippocampal Region: Organization and Role in Cognitive Functions examines the architecture and activity of this section of the temporal lobe, describes the systems active in memory, perception and behaviour, and outlines the significance of its involvement in the progress of a range ofdisease states. It provides an overview of our current basic and clinical knowledge and a baseline for further expansion of the functional understanding of the region.With contributions from an international team of authors this book will be of interest to neuroscientists, researchers and practitioners from the fields of neuropsychology, neurology and psychiatry, as well as to students from these disciplines.

Available in PDF, EPUB and Kindle. Book excerpt: The hippocampus is an important brain region, a true central hub for memory of various kinds and other processes. Neuropsychiatric disorders such as Alzheimer's disease, drug addiction, and schizophrenia are characterized by hippocampal alterations. The dentate gyrus of the hippocampus is a site exhibiting adult neurogenesis. This book covers the topic of the hippocampus from various perspectives. It discusses adult neurogenesis, effect of enriched environments on hippocampal plasticity, and long-term potentiation-associated gene expression. The book also addresses multiscale representations of complex environments and strategies in the hippocampus-dependent spatial tasks. Finally, insight into the hippocampus as a link between negative affect and relapse to psychostimulants is provided. The book collects evidence of various hippocampal functions in healthy and disordered brain.
Download or read book The Hippocampus written by Philippe Taupin and published by Nova Publishers. This book was released on 2007 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hippocampus , the Greek word for seahorse, is one of the most fascinating and intriguing regions of the mammalian brain. It is a bilateral incurved seahorse-shaped structure of the cerebral cortex. The hippocampus has a highly distinctive morphology. It is composed of two regions, the dentate gyrus (DG) and the Cornu Ammonis (CA). The nerve cells of the main layer of the DG and CA regions, the granule cells and pyramidal cells respectively, are organised in a tri-synaptic lamellaire circuit. The granule and pyramidal cells are glutamatergic excitatory. The granule cells elicit unique histological, biochemical, developmental, physio- and pathological features. The hippocampus is also an area of the brain that elicits a high degree of plasticity, like synaptic and phenotypic plasticity. It is also one of the few regions of the brain where neurogenesis, the generation of new nerve cells, occurs throughout adulthood. The hippocampus is involved in physio-and pathological processes, like learning and memory.

Download or read book The Hippocampus written by Robert Isaacson and published by Springer. This book was released on 2012-12-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: These books are the result of a conviction held by the editors, authors, and publisher that the time is appropriate for assembling in one place information about functions of the hippocampus derived from many varied lines of research. Because of the explosion of research into the anatomy, physiology, chemistry, and behavioral aspects of the hip pocampus, some means of synthesis of the results from these lines of research was called for. We first thought of a conference. In fact, officials in the National Institute of Mental Health suggested we organize such a conference on the hippocampus, but after a few tentative steps in this direction, interest at the federallevel waned, probably due to the decreases in federal support for research in the basic health sciences so keenly feit in recent years. However, the editors also had co me to the view that conferences are mainly valuabIe to the participants. The broad range of students (of all ages) of brain behavior relations do not profit from conference proceedings unless the proceedings are subsequently published. Furthermore, conferences dealing with the functional character of organ systems approached from many points of view are most successful after participants have become acquainted with each other's work. Therefore, we believe that a book is the best format for disseminating information, and that its publication can be the stimulus for many future conferences.
Download or read book Behavioural Brain Research in Naturalistic and Semi Naturalistic Settings written by E. Alleva and published by Springer. This book was released on 1995-07-31 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: The September 1994 NATO ASI, held in Acquafredda di Maratea, Italy, had the goal of filling a gap in the behavioral neuroscience of mammals, namely the relations between ecology and behavior in the so- called laboratory species (today mostly mice and rats). To this end, a group of neuroscientists who have developed an approach of combining laboratory and field techniques for the study of brain, behavior, and ecology in singing and food-storing birds were brought together with students of mouse and rat behavior with a penchant towards evolutionary biology. The proceedings, including informal discussion groups, are organized in four parts: brain, behavior, ontogeny, and evolution; bird studies; hippocampus--a hot issue; and behavioral brain research, methodology, and telemetry.
