Fetal Development

The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."

This unique book delves into the mysteries of human fetal growth and maturation. Growing knowledge in genetics indicates that factors that impact on/influence fetal growth and maturation may have a role in determining a person’s health and disease in later years. Placental, maternal, environmental, nutrient as well as fetal genome factors each play a role in producing a healthy, unhealthy or abnormal baby. A study of fetal growth and maturation is therefore basic to the understanding of why fetal growth problems occur, what implications these can have for adult disease, and how clinical intervention can help to reverse growth problems. The present study will be comprehensive and will be a major contribution to the fields of gynecology, genetics, obstetrics, biochemistry, molecular biology and clinical medicine. It will include cutting edge research in the field as well as explorations on clinical interventions in fetal growth, which will not only add to existing knowledge but also prompt future research. The two Editors are distinguished in their fields and both have extensive clinical and research experience. They felt that they could use their expertise to create a book that will help students, practitioners, researchers and others to understand the subject of gestation, growth and maturation and its implications from a multi-dimensional point of view, which will help them develop their own expertise in a cutting-edge and developing field. They have brought toget her medical scientists, clinical practitioners, embryologists, endocrinologists, immunologists, gynecologists, obstetricians, reproductive and molecular biologists, geneticists and many others to create a state-of-the-art book on a subject with increasing demand for further knowledge. It aims to integrates different disciplines to give a holistic view of human fetal growth maturation.

Based on the presentations given by well-known specialists at a recent multidisciplinary conference of developmental psychobiologists, obstetricians, and physiologists, this book is the first exhaustive attempt to synthesize the present scientific knowledge on fetal behavior. Utilizing a psychobiological analytic approach, it provides the reader with an overview of the perspectives, hypotheses, and experimental results from a group of basic scientists and clinicians who conduct research to elucidate the role of fetal behavior in development. Experimental and clinical as well as human and animal data are explored via comparative developmental analysis. The ontogeny of fetal spontaneous activity -- via the maturation of "behavioral states" -- and of fetal responsiveness to sensory stimulation is studied in detail. Results are provided from studies of embryonic/fetal and newborn behavior in chicks, rats, sheep, primates, and humans. Knowledge of fetal behavior is crucial to the obstetrician, neonatologist, developmental psychologist, and even the future parents, in order to follow and assess the gradual development of spontaneous responsive movements of the fetus. While assessing this important information, this text also examines the neuro-behavioral events taking place during the fetal period as an aid to understanding normal and pathological life span development.

This book provides an overview of fetal psychobiological research, focusing on brain and behavior, genetic and epigenetic factors affecting both short and long-term development, and technological breakthroughs in the field. These focal points intersect throughout the chapters, as in the challenges of evaluating the fetal central nervous system, the myriad impacts of maternal stressors and resiliencies, and the salience of animal studies. It also discusses specific monitoring and assessment methods, including cardiotocography, biomagnetometry, 4D ultrasound, in utero MRI, and the KANET test. Spanning assessment, identification, and pre- and postnatal intervention, the book weighs the merits of standardized evaluations and argues for more integrative research in the future. Included in the coverage: Effects on the fetus of maternal anxiety, depression, and stress during pregnancy. Clinical and experimental research in human fetuses and animal models. Observational research including the use of behaviors in developing tests to assess fetal health. Fetal auditory processing and implications for language development. Fetal effects of prenatal exposure to selective SRI antidepressant exposure. Structural and functional imaging of the prenatal brain. The effects of alcohol exposure on fetal development. Fetal Development: Research on Brain and Behavior, Environmental Influences, and Emerging Technologies is an essential resource for researchers, clinicians and related professionals, as well as students in a wide range of fields such as developmental psychology, pediatric and obstetrical medicine, neuroscience, nursing, social work, and early childhood education.

It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.

A valuable insight into fetal growth and development across all the main body systems.

Recent scientific breakthroughs, celebrity patient advocates, and conflicting religious beliefs have come together to bring the state of stem cell researchâ€"specifically embryonic stem cell researchâ€"into the political crosshairs. President Bush's watershed policy statement allows federal funding for embryonic stem cell research but only on a limited number of stem cell lines. Millions of Americans could be affected by the continuing political debate among policymakers and the public. Stem Cells and the Future of Regenerative Medicine provides a deeper exploration of the biological, ethical, and funding questions prompted by the therapeutic potential of undifferentiated human cells. In terms accessible to lay readers, the book summarizes what we know about adult and embryonic stem cells and discusses how to go about the transition from mouse studies to research that has therapeutic implications for people. Perhaps most important, Stem Cells and the Future of Regenerative Medicine also provides an overview of the moral and ethical problems that arise from the use of embryonic stem cells. This timely book compares the impact of public and private research funding and discusses approaches to appropriate research oversight. Based on the insights of leading scientists, ethicists, and other authorities, the book offers authoritative recommendations regarding the use of existing stem cell lines versus new lines in research, the important role of the federal government in this field of research, and other fundamental issues.
