Download or read book Guidance Cues in the Developing Brain written by Ivica Kostovic and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many complex molecular interactions are involved in the development of the mammalian brain. Molecules serving as guidance cues for migratory cells, growing axons and for recognition of postsynaptic targets are a major topic for research because they are directly involved in the formation of neuronal circuits, thus creating the foundation for subsequent functional refinement through interactions with the environment. In addition, most guidance cue molecules are also involved in plasticity, damage repair and regeneration in the adult brain. This volume reviews current knowledge on major classes of molecules involved in: guidance of growing axons; tau proteins involved in the establishment of axonal polarity, outgrowth and contact recognition; gangliosides and lectins involved in neuronal migration, neurite outgrowth and contact recognition; and myelin molecules that inhibit nerve regeneration.
Download or read book Neuronal Guidance written by Marc Tessier-Lavigne and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the development of the brain growing nerves send out neuronal processes (axons and dendrites) that connect them to other nerve cells, sensory organs, and muscle tissue. Correct targeting of these is the basis for wiring of the entire nervous system and depends on attractive and repulsive molecular cues that guide the developing neurons to the appropriate destination. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology examines the mechanisms underlying neuronal guidance and branching and their roles in the development and function of the nervous system. The contributors examine the major guidance cues and their receptors, the intracellular signaling pathways they activate, and their function in the context of important phenomena such as laminar organization and dendrite spacing. Other chapters consider the roles of guidance cues in development of neuronal circuits dedicated to the processing of particular sensory stimuli, such as the visual and olfactory systems. In addition, they cover the roles played by guidance cues and their receptors in neuronal regeneration and human genetic disorders, revealing important clinical implications of work in this field. The book also contains chapters discussing the function of guidance molecules in other processes, such as neuronal cell body migration, axon pruning, and regulation of neuronal cell death. In addition, it explores their roles outside the nervous system for example, in development of the vasculature. This volume is thus of general interest to cell and developmental biologists, as well as all neurobiologists interested in how the nervous system develops and functions.

Book excerpt: "The role of axon guidance cues during development has been extensively investigated. However, the expression of many of these cues, including the canonical axon guidance cue netrin-1 and its receptor Deleted in Colorectal Cancer (DCC), as well as the receptor protein tyrosine phosphatase [sigma] (RPTP[sigma]), remain long after development is complete, and can be detected in the adult mammalian nervous system, suggesting that these proteins may have roles beyond guidance.Here, we begin by investigating the role of the netrin-1 receptor DCC in synaptic regulation. We address the role of DCC in the arborization of neurites, which modulates the amount of synaptic connections that may be formed, and find that DCC plays a key role in netrin-1 induced neurite branching, through mechanisms that may be independent of netrin-1 induced axon outgrowth. In the mature nervous system, DCC is found to be enriched at synapses. Use of a transgenic mouse model engineered to conditionally delete DCC from forebrain neurons after axon guidance is complete shows that DCC regulates dendritic spine size, and is essential for both spatial and recognition memory. Furthermore, electrophysiologically, DCC deficient mice exhibit impaired long term potentiation (LTP), and a decrease in activated Src family kinases, which have previously been shown to have an essential role in regulating the NMDA receptors (NMDARs) to permit LTP. The impairment in LTP can be rescued through the facilitation of NMDARs by slight alterations in the extracellular recording solution, and through pharmacological activation of Src. We thus conclude that DCC regulates the induction of LTP through an established pathway that includes the activation of Src to modulate NMDAR function.RPTP[sigma], another cue previously implicated in axon guidance, was also found to be enriched in synaptic membranes in the mature brain. Using a transgenic mouse null for RPTP[sigma], we find that in the mature brain, RPTP[sigma] restricts aberrant sprouting, regulates spine density in vitro and in vivo, affects the synaptic properties of hippocampal cells, and alters performance in a behavioural test assessing recognition memory. Together, these results suggest the presence of increased synaptic connections in RPTP[sigma] deficient mice. Overall, we show that cues formerly implicated in axon guidance have roles beyond development, with their expression in the adult nervous system leading to synaptic regulation in the mature brain." --

Download or read book Creating Connections in the Developing Brain written by Ilan Gobius and published by Biota Publishing. This book was released on 2011-07-01 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The corpus callosum is the largest fibre tract in the human brain and subserves many of the brain’s higher-order functions. Disconnection syndromes resulting from surgical ablation, developmental absence (agenesis of the corpus callosum), disease, or injury of the corpus callosum can have profound consequences on cognition. Callosal development involves an intricate series of sequential and concurrent processes, including telencephalic induction, midline tissue patterning, production and specification of callosal neurons. In addition, axon extension and long-range axonal guidance from one hemisphere to the other are required for functional circuit formation in the contralateral hemisphere. Genetic or traumatic disruption to any part of this sequence is pathogenic. Understanding the key processes involved in callosal development is the first step in providing both better neuropsychological outcomes and improved diagnostic and prognostic tools for congenital disconnection syndromes in the future.

Download or read book How People Learn II written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2018-09-27 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many reasons to be curious about the way people learn, and the past several decades have seen an explosion of research that has important implications for individual learning, schooling, workforce training, and policy. In 2000, How People Learn: Brain, Mind, Experience, and School: Expanded Edition was published and its influence has been wide and deep. The report summarized insights on the nature of learning in school-aged children; described principles for the design of effective learning environments; and provided examples of how that could be implemented in the classroom. Since then, researchers have continued to investigate the nature of learning and have generated new findings related to the neurological processes involved in learning, individual and cultural variability related to learning, and educational technologies. In addition to expanding scientific understanding of the mechanisms of learning and how the brain adapts throughout the lifespan, there have been important discoveries about influences on learning, particularly sociocultural factors and the structure of learning environments. How People Learn II: Learners, Contexts, and Cultures provides a much-needed update incorporating insights gained from this research over the past decade. The book expands on the foundation laid out in the 2000 report and takes an in-depth look at the constellation of influences that affect individual learning. How People Learn II will become an indispensable resource to understand learning throughout the lifespan for educators of students and adults.

Download or read book Transforming the Workforce for Children Birth Through Age 8 written by National Research Council and published by National Academies Press. This book was released on 2015-07-23 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: Children are already learning at birth, and they develop and learn at a rapid pace in their early years. This provides a critical foundation for lifelong progress, and the adults who provide for the care and the education of young children bear a great responsibility for their health, development, and learning. Despite the fact that they share the same objective - to nurture young children and secure their future success - the various practitioners who contribute to the care and the education of children from birth through age 8 are not acknowledged as a workforce unified by the common knowledge and competencies needed to do their jobs well. Transforming the Workforce for Children Birth Through Age 8 explores the science of child development, particularly looking at implications for the professionals who work with children. This report examines the current capacities and practices of the workforce, the settings in which they work, the policies and infrastructure that set qualifications and provide professional learning, and the government agencies and other funders who support and oversee these systems. This book then makes recommendations to improve the quality of professional practice and the practice environment for care and education professionals. These detailed recommendations create a blueprint for action that builds on a unifying foundation of child development and early learning, shared knowledge and competencies for care and education professionals, and principles for effective professional learning. Young children thrive and learn best when they have secure, positive relationships with adults who are knowledgeable about how to support their development and learning and are responsive to their individual progress. Transforming the Workforce for Children Birth Through Age 8 offers guidance on system changes to improve the quality of professional practice, specific actions to improve professional learning systems and workforce development, and research to continue to build the knowledge base in ways that will directly advance and inform future actions. The recommendations of this book provide an opportunity to improve the quality of the care and the education that children receive, and ultimately improve outcomes for children.

This book was released on 2019-07-26 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adolescenceâ€"beginning with the onset of puberty and ending in the mid-20sâ€"is a critical period of development during which key areas of the brain mature and develop. These changes in brain structure, function, and connectivity mark adolescence as a period of opportunity to discover new vistas, to form relationships with peers and adults, and to explore one's developing identity. It is also a period of resilience that can ameliorate childhood setbacks and set the stage for a thriving trajectory over the life course. Because adolescents comprise nearly one-fourth of the entire U.S. population, the nation needs policies and practices that will better leverage these developmental opportunities to harness the promise of adolescenceâ€"rather than focusing myopically on containing its risks. This report examines the neurobiological and socio-behavioral science of adolescent development and outlines how this knowledge can be applied, both to promote adolescent well-being, resilience, and development, and to rectify structural barriers and inequalities in opportunity, enabling all adolescents to flourish.
