Should parents aim to make their children as normal as possible to increase their chances to "fit in"? Are neurological and mental health conditions a part of children's identity and if so, should parents aim to remove or treat these? Should they aim to instill self-control in their children? Should prospective parents take steps to insure that, of all the children they could have, they choose the ones with the best likely start in life? This volume explores all of these questions and more. Against the background of recent findings and expected advances in neuroscience and genetics, the extent and limits of parental responsibility are increasingly unclear. Awareness of the effects of parental choices on children's wellbeing, as well as evolving norms about the moral status of children, have further increased expectations from (prospective) parents to take up and act on their changing responsibilities. The contributors discuss conceptual issues such as the meaning and sources of moral responsibility, normality, treatment, and identity. They also explore more practical issues such as how responsibility for children is practiced in Yoruba culture in Nigeria or how parents and health professionals in Belgium perceive the dilemmas generated by prenatal diagnosis.

Specialist Periodical Reports provides systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemists, applying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

This volume provides a highly integrated view of attention-related events, taking the reader from individual molecular interactions through the regulation of neuronal circuits to our higher order capacity for selective amplification of particular information.

Neuroscientists, psychologists, psychiatrists and other professionals dealing with psychiatric illnesses such as ADHD, autism, and schizophrenia will find this volume a useful addition to their library.

This timely book critically examines the capabilities and limitations of the new areas of biology that are used as powerful arguments for developing social policy in a particular direction, exploring their implications for policy and practice. It will enable social scientists, policy makers, practitioners and interested general readers to understand how the new biologies of epigenetics and neuroscience have increasingly influenced the fields of family policy, mental health, child development and criminal justice

We all seem to think that we do the acts we do because we consciously choose to do them. This commonsense view is thrown into dispute by Benjamin Libet's eyebrow-raising experiments, which seem to suggest that conscious will occurs not before but after the start of brain activity that produces physical action.
Libet's striking results are often claimed to undermine traditional views of free will and moral responsibility and to have practical implications for criminal justice. His work has also stimulated a flurry of further fascinating scientific research--including findings in psychology by Dan Wegner and in neuroscience by John-Dylan Haynes--that raises novel questions about whether conscious will plays any causal role in action. Critics respond that both commonsense views of action and traditional theories of moral and legal responsibility, as well as free will, can survive the scientific onslaught of Libet and his progeny. To further this lively debate, Walter Sinnott-Armstrong and Lynn Nadel have brought together prominent experts in neuroscience, psychology, philosophy, and law to discuss whether our conscious choices really cause our actions, and what the answers to that question mean for how we view ourselves and how we should treat each other.

This volume reviews recent findings on the regulation of exocytotic release of neurotransmitters from nerve terminals. Leading international investigators examine the properties and composition of the vesicles that store neurotransmitters and the molecular and cellular mechanisms that cause a vesicle to release transmitters in response to a nerve impulse.
Coverage includes detailed analyses of quantal release of transmitters in the central and peripheral nervous systems. These studies shed new light on the questions of whether different transmitters are released together in fixed amounts and proportions, and whether and why effectors respond to such "transmitter quanta" in a quantal fashion. The book also highlights the relevance of research on neurotransmitter release to the study of various forms of synaptic plasticity, including higher functions such as learning and memory.

This book is a collection of articles by leading researchers working at the cutting edge of neuro-computational modelling of neurological and psychiatric disorders. Each article contains model validation techniques used in the context of the specific problem being studied. Validation is essential for neuro-inspired computational models to become useful tools in the understanding and treatment of disease conditions. Currently, the immense diversity in neuro-computational modelling approaches for investigating brain diseases has created the need for a structured and coordinated approach to benchmark and standardise validation methods and techniques in this field of research. This book serves as a step towards a systematic approach to validation of neuro-computational models used for studying brain diseases and should be useful for all neuro-computational modellers.

Many advances in modern neuroscience are enabled by the availability of chemical tools that allow sensitive, precise, and quantitative measurements of, and control over, biological processes. These powerful reagents are widely used for investigating the nervous system at levels of detail ranging from ion channel structure to neural network dynamics. Recent advances in photochemistry, microscopy, and protein engineering have triggered a surge in the development and application of these interdisciplinary techniques. Chemical Neurobiology: Methods and Protocols assists with the design, characterization and validation of new chemical tools for neurobiology by providing detailed protocols of procedures and assays deemed essential for the successful development and implementation of such tools. Divided into three sections, topics cover chemical probes of membrane protein structure and function, photochemical control of protein and cellular function, and chemical probes for imaging in the nervous system. Written in the successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Chemical Neurobiology: Methods and Protocols serves scientists at many levels, including students aiming to expand their perspective, laboratory researchers seeking technical guidance, and established investigators looking for creative solutions to their research problems in molecular, cellular and systems neuroscience.

Human consciousness has perplexed philosophers, artists and scientists for centuries. Some hold it to be purely physical, while others believe it transcends the material world. Now comes a book that offers a new perspective - based entirely on evidence from the natural sciences - whereby materialism and dualism co-exist. The author - a distinguished pioneer of nonlinear dynamics - bases his argument on a hierarchical view of mental organization; a stairway. Atoms give rise to molecules, neurons form the brain and individual consciousness leads to shared culture. All steps are needed to complete the picture and each level derives from the previous one. The book shows specialists how each of their fields adds to the overall picture, while providing general readers with an introduction to this investigation.

The book presents a new, powerful model of neuronal networks, consisting of a three-dimensional neuronal culture in which 3D neuronal networks are coupled to micro-electrode-arrays (MEAs). It discusses the main advantages of the three-dimensional system compared to its two-dimensional counterpart, and shows that the network dynamics, recorded during both spontaneous and stimulated activity, differs between the two models, with the 3D system being better able to emulate the in vivo behaviour of neural networks. The book offers an extensive analysis of the system, from the theoretical background, to its design and applications in neuro-pharmacological studies. Moreover, it includes a concise yet comprehensive introduction to both 2D and 3D neuronal networks coupled to MEAs, and discusses the advantages, limitations and challenges of their applications as cellular and tissue-like in vitro experimental model systems.

This book focuses on the role of gangliosides in three areas of medicine in which rapid progress has been made in the last decade: cancer, peripheral neuropathies and Alzheimer's disease. The volume further reflects progress in the pathogenesis of peripheral neuropathies, and the controversial role of gangliosides, also in therapeutic administration. There is a section on the role of gangliosides in neuronal differentiation and development and their receptor functions and cell surface activities. This excellent addition to the renowned "Progress in Brain Research" series also contains an invaluable plenary lecture on molecular basis of cell adhesion by Nobel prizewinner Gerald Edelman.

Transcriptomics and proteomics, studying the profile of the expression of nucleic acids and proteins respectively, are increasingly applied to gain a mechanistic insight into a wide spectrum of investigation, and the use of expression profiling studies for the central nervous system and brain function aids in the understanding of neurodegenerative disorders and tumor development mechanisms. In Expression Profiling in Neuroscience, expert researchers provide a survey of the most commonly used approaches in the field and scan the different ways of studying the central nervous system/brain environment through expression profiling. The first part addresses the gene expression profiling of the brain at a large scale or to a specific cell type such as blood-brain barrier endothelium. Then, the second part describes the protein expression studies and the different technologies applied. Written for the popular Neuromethods series, chapters include corresponding background information, tested laboratory protocols, and step-by-step methods for reproducible laboratory experiments. Detailed and authoritative, Expression Profiling in Neuroscience presents the state-of-the-art techniques necessary to expand research further into this vital area of study.

Exocytosis is a fundamental cellular process that is used by eukaryotic cells to release a variety of biological compounds including peptide hormones and neurotransmitters or to insert specific lipids and proteins in the plasma membrane. In recent years, a multidisciplinary approach promoted an extraordinary progress in the understanding of the molecular mechanisms regulating exocytosis. This led to the discovery of a large number of components belonging to the machinery that governs the fusion of secretory vesicles with plasma membranes in different cell systems, including neuronal and endocrine cells. The basic machinery required for vesicle fusion turned out to be well conserved through evolution from yeast to man. So far, because of the large number of components involved, understanding of the molecular basis of exocytosis has remained the privilege of a relatively small group of specialists. This book, written by recognized experts in the field aims at clarifying for a non-specialist audience the role of the key players in the exocytotic process not only in neuronal and endocrine cells but also in a variety of other relevant cell systems. introduce researchers and students to the forefront of this rapidly moving and fascinating field.

This edited monograph provides a compelling analysis of the interplay between neuroscience and aesthetics. The book broaches a wide spectrum of topics including, but not limited to, mathematics and creator algorithms, neurosciences of artistic creativity, paintings and dynamical systems as well as computational research for architecture. The international authorship is genuinely interdisciplinary and the target audience primarily comprises readers interested in transdisciplinary research between neuroscience and the broad field of aesthetics.

Neuroscience Perspectives provides multidisciplinary reviews of topics in one of the most diverse and rapidly advancing fields in the life sciences.
Whether you are a new recruit to neuroscience, or an established expert, look to this series for 'one-stop' sources of the historical, physiological, pharmacological, biochemical, molecular biological and therapeutic aspects of chosen research areas.
Although peripheral type benzodiazepne recognition sites have been demonstrated in the brain and peripheral organs of various species for more than 10 years, the exact physiological function or pharmacological effects have not yet been established. Peripheral benzodiazepine literature is so overwhelming that the novice may find it virtually impossible to form a clear idea about the diverse findings.
This volume, dedicated exclusively to pBR and their natural and synthetic ligands, puts the available data into perspective.
A truly interdisciplinary approach has brought neuroscientists, cardiologists, endocrinologists, and immunologists together to work on the description of pBR-mediated effects. The chemistry, biochemistry, and molecular biology of the pBR receptor and its ligands are reviewed, their pharmacological usefulness is conjectured, and thus a true overview of the field is provided.
* SPECIAL FEATURES
* This volume follows the Neuroscience Perspectives brief of providing a historical background, pharmacological, biochemical and physiological aspects of research and therapeutic potential, of its chosen topic.
* The peripheral benzodiazepine recognition site has been recognised for more than ten years, but the exact physiological and pharmacological effects have not yet been established.

A comprehensive survey of the many recent advances in the field of G protein-coupled receptors (GPCR). The authors describe the current knowledge of GPCR receptor structure and function, the different mechanisms involved in the regulation of GPCR function, and the role of pharmacological chaperones in GPCR folding and maturation. They also present new findings about how GPCR dimerization/oligomerization modifies the properties of individual receptors and show how recent developments are leading to significant advances in drug discovery, such as the detection of ligands for orphan GPCRs. Also discussed are the most recent developments that could lead to new drug discoveries: the role of GPCRs in mediating pain, the development of receptor-type selective drugs based on the structural plasticity of receptor activation, and the identification of natural ligands of orphan GPCRs (deorphanization) as possible drug targets.

Computational Neurosciences is a burgeoning field of research where only the combined effort of neuroscientists, biologists, psychologists, physicists, mathematicians, computer scientists, engineers and other specialists, e.g. from linguistics and medicine, seem to be able to expand the limits of our knowledge.

The present volume is an introduction, largely from the physicists' perspective, to the subject matter with in-depth contributions by system neuroscientists. A conceptual model for complex networks of neurons is introduced that incorporates many important features of the real brain, such as various types of neurons, various brain areas, inhibitory and excitatory coupling and the plasticity of the network. The computational implementation on supercomputers, which is introduced and discussed in detail in this book, will enable the readers to modify and adapt the algortihm for their own research. Worked-out examples of applications are presented for networks of Morris-Lecar neurons to model the cortical connections of a cat's brain, supported with data from experimental studies.

This book is particularly suited for graduate students and nonspecialists from related fields with a general science background, looking for a substantial but hands-on introduction to the subject matter. "

Dr. Howard House, founder of the House Ear Institute and House Ear Clinic often uses the analogy of planting a seed when referring to establishing the House Ear Institute in 1946. Two grateful patients of Dr. House put forth the idea that his knowledge and innovative skills could be used to expand the understanding of hearing impairment and its treatment. Those two early patients provided the "seed money" to begin the Institute. Since that time, the growth has been phenomenal from a one-man laboratory to a multidisciplinary facility boasting over 175 scien tists, physicians, and support staff, all dedicated to the advancement of otologic research and education. Six years ago after a half-century of remarkable success with prosthetic and device research, the Institute began cultivating a new field of endeavor-cell and molecular biology. Don Nielsen, then the Institute's Executive Vice President for Research and Scientific Director, began exploring the potential for hair cell regen eration and presented his ideas to the Board of Trustees. For a period of six months, we did a lot of fact finding to assess what role the Institute might take in this excit ing new field."

This volume presents the most current reviews on how cancer stem cells (CSCs) hypothesis dictates that the continued proliferation of a tumor is dependent on a sub-population of self-renewing and asymmetrically dividing neoplastic stem cells that supply a largely differentiated tumor. This volume provides a comprehensive overview of the characteristics of CSCs, their role in central nervous system (CNS) tumors, and the recent CSC-specific treatment modalities being used. The emerging focus on CSCs in brain tumors represents a paradigm shift in our understanding of the pathogenesis of these neoplasms. Importantly, the realization that a distinct sub-population of cells contributes disproportionately to the growth and sustenance of central nervous system tumors has important implications for the treatment of such tumors. To treat CNS tumors, there is now a growing need to treat CSCs to achieve adequate tumor control.

Cerebral hypoxia/ischemia is a common cause of neurologic dysfunction following cardiopulmonary resuscitation. With the advent of aggressive resuscitatiQ,il;m.ethods to treat cardiopulmonary arrest, more patients are surviving to live with posthypoxic/ postischemic neurologic syndromes. Thus, there is an urgent need to understand the basic aspects of the problem. This monograph consists of reviews from :s'c5ientists using advanced techniques for basic research into the molecular neurob~ology of the mechanisms and effects of cerebral hypoXia/ischemia, and from cliniciahs ~ctively involved in managing patients with these syndromes. The first five chapters contain several basic topics of neurobiology to help under- stand brain function, followed by five chapters that deal with the mechanisms of cerebral hypoxia/ischemia and potential protective measures against it. The first chapter describes functional proteins in the presynaptic terminal which regulate transmitter release. This is followed by a chapter demonstrating the molecu- lar structure and physiological function of the glutamate receptor channel, which may determine the rate and quantity of calcium ion influx into the nerve cell. The third chapter surveys the metabolic glutamate responses and the intracellular mechanisms believed to play an important role in pathogenesis of hypoxic/ischemic cell injury. The fourth chapter deals with long-term potentiation and drugs, the basis for under- standing memory disturbance caused by cerebral hypoxia/ischemia. The fifth chapter describes distributions of nitric oxide synthase mRNAs in the brain, currently one of the most advanced fields in neurobiology.
