Neurology and clinical neurophysiology Books

Book SynopsisThe last several years have seen a dramatic increase in the number of neurobiologists building or using computer-based models as a regular part of their efforts to understand how different neural systems function. As experimental data continue to amass, it is increasingly clear that detailed physiological and anatomical data alone are not enough to infer how neural circuits work. Experimentalists appear to be recognizing the need for the quantitative approach to explore the functional consequences of particular neuronal features that are provided by modeling. This combination of modeling and experimental work has led to the creation of the new discipline of computational neurosciences. More than the use of models per se, the authors believe that computational neuroscience is most distinguished from classical neurobiology due to an explicit focus on how the nervous system computes. Thus, instead of obtaining experimental information about the structure of the nervous system for its own sake, a computational approach involves collecting the information most relevant to the advancement of functional understanding. In our hands, models, especially those based on the detailed physiology and anatomy of the brain region in question, capture what is known about this region while also directing further experimental investigations. These same models can then provide an interpretation for the obtained data. Thus, the interaction between experiments and computer modeling is increasingly iterative and interdependent.

Book SynopsisPerhaps no artery in the human body bears as much importance to bodily functions and life as the basilar artery, by virtue of the anatomical territories it serves. This is due to the critical nature of the physiological functions supported by the brainstem, the nearby cerebellum and cerebrum, and the severity of most pathological conditions known to affect this artery, and the risk involved in treating those conditions. This book is a comprehensive resource of knowledge on the anatomical, radiological, developmental, clinical, and technical aspects relevant to the diagnosis and treatment of basilar artery diseases. Until now, no single book has been available as a wide-ranging resource of clinically relevant information on the basilar artery, its pathology, and various treatment options. The co-editors are experienced academic clinicians with active interests in clinical neurovascular imaging and cerebrovascular surgery, who have worked within vibrant hospital and academic settings at the forefront of the best clinical practices related to diseases involving the basilar artery. The co-editors clinical experience has been acquired in centers of excellence across the USA, Europe, and the Far East. In compiling this book, the co-editors have also called upon many of the worlds best basic and clinical neuroscientists, specializing in knowledge of clinical conditions affecting the basilar artery, for their expert input on the latest clinical management of patients with diseases involving this artery. This book is intended for neuroradiologists, neurosurgeons, neurologists, neurointensivists, and other physicians and scientists engaged in the study and clinical management of patients with disease of the basilar artery and its vascular territories of the brain. It should also serve as a unique educational and research resource for students and more experienced practitioners alike within this important area of clinical medicine.

Book SynopsisNeuroimaging techniques that can help elucidate and characterize the nature and mechanism of tissue injury and disease progression in neurodegenerative disease are of particular importance given its their roles in seeking successful preventive and therapeutic treatments. Studying large-scale samples with various disease mechanisms using multi-parametric imaging, as well as revealing the correlations between the neuroimaging metrics and clinical data including neurocognitive function and neuropsychological inventories to elucidate multiple factors affecting the neurodegeneration processes in brain are the main topics of this book. In addition, the neural underpins of cognitive and psychological functions with advanced functional imaging techniques can provide better cross-validation and clinical symptom relevance of multi-parametric data. Expanding the current findings with higher diagnosis accuracy and detection specificity in multiple neurodegenerative diseases as well as better differentiation of each type are the ultimate goal. The results in this book will extend the current notion of diagnosis value of various relatively new imaging techniques in multiple neurodegenerative diseases including traumatic brain injury, post-traumatic stress disorder, multiple sclerosis and early stage of Alzheimer's disease such as mild cognitive impairment. Specifically, the neurobiology and related imaging findings of the four representative neurodegenerative diseases will be introduced and reviewed, including brain region-specific and disease-related alterations, unique clinical symptom of each disease, as well as previous findings and challenges. There is an increasing body of literature suggesting that damage to the default mode network, hypothalamus, thalamus and hippocampus neuronal networks and local injuries might be under-diagnosed and may account for some of the sequelae following the neurodegenerative injuries including trauma and dementia. The relatively novel imaging results to differentiate each disease using advanced functional connectivity, neuronal activity, microstructure integrity analysis based on structural connectivity, multi-dimensional morphometry and molecular imaging tracers including amyloid and tau for neuropathological burden quantification were presented to differentiate each type of disease. We then briefly reviewed some of the therapeutic effects of traditional Chinese medicine with neuroimaging quantifications to help treating neurodegenerative diseases. Finally, our work proves that the multi-parametric neuroimaging methods with more than twelve metrics and numerous tight clinical association data presented in this book are the most forefront and up-to-date with enough sensitivity, precision and resolution. Taken together, multiple neuroimaging metrics haved been demonstrated in this book to identify and quantify significant and distinct brain alterations at function, microstructure, morphology and molecular scales in different types of neurodegenerative diseases with high sensitivity and specificity. These comprehensive imaging features could be combined to improve disease diagnosis accuracy. The aim of this book is thus intended to provide both beginners and experts in biomedical imaging and health care a broad and complete picture as well as the new developments of using multiple metrics in improving disease identification and diagnosis accuracy. This book would hopefully capture the interests of colleagues interested in neurodegenerative disease diagnosis and treatment, and could help convey the methodological and integrative perspectives of multi-parametric neuroimaging applications.

Book SynopsisThis book provides a transformative approach to the understanding of mental health in the 21st century. It does so by encouraging the replacement of traditional subjective techniques with more precise and objective measures that are designed to discover individual differences in our patients. Just as in personalized medicine, where diagnostic and treatment techniques are becoming more targeted toward the specific conditions of a particular patient, so to in the mental health field we need to develop targeted and focused methods through the use of clinical science concepts and through the adoption of an agnostic, unassuming posture where the presentation of each patient is viewed as unique. For example, treatments may draw from an integrative approach that incorporates genomic and epigenomic analyses of the patient to inform a more targeted medication regimen or psychotherapy approach (some psychiatrists are beginning to use genomic analysis to aid in the choice of a specific antidepressant, for example, that would most likely be effective for a certain patient). Diagnostically, paper and pencil questionnaires leading to current diagnostic labels, long the standard, must be replaced, for the most part, by objective measures of stress that prioritize "reports from the body". Additionally, research methods of extremely complex psychological disorders can be enhanced by breaking them down into smaller subtypes (or endophenotypes) versus large phenomenologically-based symptom clusters (i.e. DSM diagnoses). Individual differences, a consistent focus throughout the book, may be the product of genetic variants and/or epigenetic mechanisms. The latter mediate gene X environment interaction that is now the primary paradigmatic lens through which we investigate and seek to explain resultant behavioural profiles. A major focus of the book is on the effects of early adversity, particularly trauma, and how they contribute to a "re-programming" of the brain through epigenetic alterations of gene expression. This results in increased vulnerability to possible psychological disorders, such as various anxiety conditions, depression, and character disorders which may manifest later in life. By identifying the epigenetic effects caused by early stressors, that is, how gene expression is altered, we can eventually make significant advances in primary prevention. This book represents an attempt to move us into a transitional domain and beyond, where causes and the treatment of psychological disorders are re-conceptualized through our developing insights from neurobiology, genetics, and epigenetics.

Book SynopsisThis book depicts the trials and tribulations when trying to restore speech to Erik who was locked-in (paralyzed and mute) at age 16. We implanted electrodes into his brain, initiating a decade of breakthrough research in speech recovery. It lead to the author's own brain implant and the consequent successful offline development of the speech prosthetic whereby mute, locked-in people can speak. Part 1 is Erik's story of how he became locked-in following a brainstem stroke, and our efforts to break him out of his locked-in state by helping him speak. It describes my decision making, the tremendous contribution of his family, their anguish and the very relevant comparison with famous locked-in people, namely, Stephen Hawking and Jean-Dominique Bauby (The Diving Bell and the Butterfly). Part 2 documents conversations between myself and Erik's Dad, Eddie. Eddie describes how he was trained in a rehabilitation hospital to take care of his son. His 16-year devotion to his son is unparalleled and heroic. This part also contains important contributions from other researchers in the field, in a question and answer format. Part 3 is a condensed version of the scientific aspects of this research written for the non-scientist. Figures and videos on the website augment the text. Importantly, there is a full documentary associated with this book.Trade ReviewThis book has come at an important time in the evolution of the brain machine interface Unlocking Erik tells the story from the human side both in terms of Erik himself as the subject, and Dr. Kennedy as the pioneer. It is a journey of quiet and slow discovery, and has taken courage and risk from all sides. -- Professor Alexander Green, Neurosurgeon, University of Oxford, England.With Dr. Kennedy widely regarded as one of the pioneers of this technology, he is uniquely placed to discuss the far-reaching consequences and ramifications of BCI, and this certainly helped attract the funding we needed to begin production of the documentary that tracks early breakthroughs in the field. -- David Burke,Dot Television, IrelandFinally, with all the excitement of machine learning, we shouldnt forget that we are talking about connecting to a neural network with more capabilities and far more creativity than anything that Google has made the human brain! So lets try to not forget the brains ability to learn. -- Andrew Jackson, Professor of Neural Interfaces, University of Newcastle, U.K."We know that neurons involved in internal "thinking" are also clearly controllable. As explored in Phil Kennedy's study of Erik, the neurons involved in generating speech are a particularly important group of volitionally controllable neurons for speech prostheses." -- Eberhard Fetz"This book tells a remarkable story. There is a group of patients rendered unable to communicate by a brutal medical misfortune. There is a new therapy involving special equipment... and there is the physician who manages their care... Dr. Kennedy has achieved remarkable success with his brain machine interfaces. He remains focused on the tremendous value of restoring speech to patients who are trapped inside their own bodies..." -- Thomas WichmannTable of ContentsPrelude: Pioneers in the Field of Brain to Computer Interfacing; Preface: Decades of Opening the Door to the Mind; Breaking the Sound Barrier; Some Superheroes Only Fly Inside; Coding and Decoding Eriks Inner Dialogue; Believing in the Magic, Counting on the Science; Unexpected Delays and Eureka Moments; The Place Where I Exists; Deep Presence: Understanding the Here and Now; The Uncharted Waters of Research: Here There Be Dragons!; Interviews with Eriks Father and Contributions from Specialists Who Comment on the Field of Locked-In Research and How It Is Evolving; Eriks Injury; Meeting Dr Kennedy; The Implant Surgery; Recording from Erik; Using Single Units to Say Da, Da.; Decoding Phonemes; Moving from Vowel to Vowel; The Effects of Emotion on Firing Rates; Music Relates to Firing Rates; Conditioning Single Units Nine Years after Implantation; Limitations of Eriks Recordings; Phils Implantation Surgery; Sensory and Motor Relationships; Decoding Most Phonemes; Decoding Audible and Silent Speech; The Future Direction: Ready to Implant Locked-In People; Why Not Use Other Electrodes and Systems?; The Future is Almost Here; Afterword: The Father of the Cyborgs; Index.

Book SynopsisCerebral small vessel disease (CSVD) silently affects a large part of the population, increasing in prevalence with age and with the presence of vascular risk factors. Its harmful effects on brain parenchyma increase the risk of stroke, cognitive decline and dementia, and it is responsible for a spectrum of symptoms that are much less obvious, such as unrecognized mild signs or symptoms of neurocognitive dysfunction, mild mood or behavioral disturbances, gait dysfunction, and a general decline in function generally attributed to normal aging. These consequences pose a heavy burden on patients, families and countries that need to be addressed. Understanding and Treating Cerebral Small Vessel Disease provides an insight into a broad area of research in this field, focusing on topics that deal with the underlying pathophysiological mechanisms of CSVD, recent clinical and neuroimaging findings, biomarker developments, comorbidities, prevention strategies and emerging therapeutic options. The contents are distributed in five sections that span these topics. Section I, "Pathophysiology and Subtypes of Cerebral Small Vessels Disease", includes three chapters that deal with the prevalence of different forms of small-vessels disease in vascular cognitive impairment, and the pathophysiological mechanisms of CSVD. Section II, "New Approaches for Diagnosis and Treatment of CSVD", includes six chapters which deal with the microvascular assessment of CSVD through the study of retinal blood (chapter four), a global vision of brain MRI findings in CSVD (chapter five), and digital electroencephalographic changes and computerized analysis methods in CSVD (chapter six). Chapters seven, eight and nine approach the treatment of CSVD, from the assessment of advanced immunoactive therapy for CSVD to the use of non-pharmacological therapies such as transcranial magnetic stimulation and extracorporeal shock wave therapy. The targeting of key pathogenic mechanisms is also discussed in light of experimental data and clinical trials, as well as the introduction of neuroprotection in the treatment of symptomatic and asymptomatic CSVD. Section III, "Potential Biomarkers for CSVD", includes chapters 10-13 dedicated to the early detection of CSVD through brain MRI imaging and the development of alternative circulating biomarkers (brain specific proteins, inflammatory and oxidative stress biomarkers, autoantibodies). The application of these biomarkers in other conditions closely associated with small vessel neurovascular networks, such as migraine, is also discussed. Section IV, "Cerebral Small Vessels Disease and Comorbid Conditions" is comprised of five chapters (14-18) which approach the relationship of CSVD with infectious diseases (viral, bacterial and parasitic infections), highlighting findings in COVID-19. Conditions related with the nervous system, such as cognitive impairment, schizophrenia and chronic alcohol consumption in association with the development of small vessel pathology in the brain are also discussed. Section V includes chapter 19, which briefly summarizes the main topics presented in this book and offers a quick vision from the editors of future trends in microangiopathy diagnosis and treatment.

Book SynopsisThere has been a paradigm shift in the understanding of the role of the cerebellum in the nervous system, which is now suggested to be an integral component of the distributed neural circuitry, subserving even higher order functions, traditionally linked to the integrity of cerebral cortex. One of these functions is reading, which is one of the most prominent learned competencies in humans. The pathophysiology of dyslexia is largely unknown. It is usually related to brain cortical alteration. Recent evidence suggests dyslexia may involve binocular instability or alterations of accommodation. This book describes the possible role of the cerebellum in reading tasks, either considering its emergent role in mentation, either considering its traditional role in motor control. It examines the possible involvement of cerebellum in reading, which may be caused by an alteration of the diffuse projections which connect the cerebellum to different cortical areas via subcortical structures, by its involvement in spatial perception, in timing processing of cortical flow of information, and by a possible intrinsic property of the structure in cognition.

Book SynopsisDespite a wealth of epidemiological evidence of the profound ill-effects of smoking on human health, we know surprisingly little about the pathogenic mechanisms by which tobacco smoke actually causes disease. Indeed, to our knowledge this publication represents the first book that is entirely devoted to the molecular and cellular mechanisms of tobacco-induced diseases. Considering that smoking will directly kill 650 million of those people currently alive, the lack of such a book represents a huge gap in the biomedical literature. This important book fills this gap.

Book SynopsisDementia is a brain disorder that seriously affects a person''s ability to carry out daily activities. The most common form of dementia among older people is Alzheimer''s Disease (AD), which involves the parts of the brain that control memory, thought and language. Age is the most important known risk factor for AD. The number of people with the disease doubles every 5 years beyond age 65. AD is a slow disease, starting with mild memory loss and ending with severe brain damage. The course the disease takes and how fast changes occur vary from person to person. On average, AD patients live from 8 to 10 years after they are diagnosed, though the disease can last for as many as 20 years. Current research is aimed at understanding why AD occurs and who is at greatest risk for developing it, improving the accuracy of diagnosis and ability to identify who is at risk, developing, discovering and testing new treatments for behavioural problems in patients with AD. This book gathers state-of-the-art research from leading scientists throughout the world which offers important information on understanding the underlying causes and discovering the most effective treatments for Alzheimer''s Disease.

Book SynopsisAlzheimer''s disease (AD) is the most common type of neurodegenerative disorder in the ageing population, with dementia as a common consequence. AD is defined pathologically by the appearance of extracellular senile plaques and intracellular neurofibrillary tangles, as described by Alois Alzheimer about a century ago. The causes for AD include genetic predisposition in a small population, ageing and environmental stresses in majority cases. The underlying pathogenic cascades, increases in expression of amyloid precursor protein and accumulation of Aß and reactive oxidant activity and inflammation, have the features of both adaptive, at least initially, and harmful when becoming excessive. Dementia, on the other hand, is a clinical diagnosis and is defined as globally, persistently impaired cognitive skills including memory. Alzheimer dementia refers to clinical dementia in patients who also have Alzheimer neuropathology. Alzheimer dementia is what brings the patients to seek medical treatments. An extraordinary inability to form new memory, especially of those episodic type, and executive dysfunction are among the earliest symptoms in AD patients. In end-stage AD, cognitive degeneration extends far beyond memory loss. The underlying causes include decreases in impaired brain metabolism, which results in impaired synaptic functions and capacities, thus impaired information processing, and eventually leads to neuronal injury and death. This book presents leading-edge research in this dynamic field.

Book SynopsisCalcium signalling is an astonishing example how a simple caption can trigger and regulate an enormous variety of cellular and physiological responses. Ca2+-signalling routes very often involve Ca2+-binding proteins that sense changes in intracellular [Ca2+] and trigger cellular responses by regulating specific targets. One fascinating group among these Ca2+-sensors are the neuronal calcium sensor (NCS) proteins, named for their localisation in neuronal tissue (although there are reports of their expression in non-neuronal tissues as well). While recent excellent reviews have covered key aspects of this protein group, the field expanded in recent years making it more and more difficult to represent every facet of this ongoing research endeavour. This book is intended to represent properties of NCS proteins.

Book SynopsisFragile X syndrome (FXS), is the most common cause of inherited mental impairment. This impairment can range from learning disabilities to more severe cognitive or intellectual disabilities (sometimes referred to as mental retardation). FXS is the most common known cause of autism or ''autistic-like'' behaviour. Symptoms also can include characteristic physical and behavioural features and delays in speech and language development. This new book presents the latest research in this field.

Book SynopsisA stroke occurs when the blood supply to the part of the brain is suddenly interrupted (ischemic) or when a blood vessel in the brain bursts, spilling blood into the spaces surrounding the brain cells (haemorrhagic). Generally, there are three treatment stages for stroke: prevention, therapy immediately after stroke, and post-stroke rehabilitation. Therapies to prevent stroke are based on treating an individual''s underlying risk factors. This book includes within its scope the prevention, risk factors, symptoms, diagnosis, treatment, and rehabilitation of stroke. Leading-edge scientific research from throughout the world is presented.

Book SynopsisIn many transduction processes, an increasing number of enzymes and other molecules become engaged in the events that proceed from the initial stimulus. In such cases the chain of steps is referred to as a "signalling cascade" or a "second messenger pathway" and often results in a small stimulus eliciting a large response. Hormones and other signalling molecules may exit the sending cell by exocytosis or other means of membrane transport. The sending cell is typically of a specialised type. Its recipients may be of one type or several, as in the case of insulin, which triggers diverse and systemic effects. This book sheds new light in this exciting field of cell transportation research.

Book SynopsisNeurofilaments serve as a necessity in brain sensory communications. They are important structural and cellular transportation proteins found in both afferent and efferent auditory neurons. The peripheral processes of auditory neurons innervate sensory hair cells within the cochlea and a loss of these hair cells, by disease or damage, is a major cause of deafness. The decline of Neurofilaments can also lead to the cause of multiple sclerosis due to their neurological involvement. This new book brings fascinating research in this field.

Book SynopsisIn neuroscience, a neural network is a bit of conceptual juggernaut: the conceptual transition from neuroanatomy, a rigorously descriptive discipline of observed structure, to the designation of the parameters delimiting a ''network'' can be problematic. In outline a neural network describes a population of physically interconnected neurons or a group of disparate neurons whose inputs or signalling targets define a recognisable circuit. Communication between neurons often involves an electrochemical process. The interface through which they interact with surrounding neurons usually consists of several dendrites (input connections), which are connected via synapses to other neurons, and one axon (output connection). If the sum of the input signals surpasses a certain threshold, the neuron sends an action potential (AP) at the axon hillock and transmits this electrical signal along the axon. This important book presents the latest research in this field.

Book SynopsisIn recent years, a substantial number of imaging studies have addressed the neuronal processes underlying recovery after stroke. Although difficult to achieve, several longitudinal studies assessed both clinical recovery and imaging patterns over time and give important inside into the plasticity of the stroked brain. This tendency is supported by the fact that it has become possible to depict biological processes at the cellular and molecular level. Of primary interest is the development of methods using MRI and PET with which the different kinds of progress of therapy in acute ischemic stroke can be monitored and graphically displayed. The emerging studies of brain plasticity and its modulation by drugs and other therapies indicate potentially useful approaches to the rehabilitation of adults with brain damage, including damage resulting from cerebral ischaemia. State-of-the-art imaging technology is already being developed to image genes and their impact on cellular function in laboratory animals. Eventually, this may also be possible in humans. Main attention is given to imaging the post-stroke phase and its implication on treatment. This book gives important insight in the future of imaging in stroke and their interaction with clinical aspects. Stroke care has become a specialised field, requiring input from different sub-specialists forming a multidisciplinary team.

Book SynopsisNeuroimmunology is a rapidly-growing branch of biomedical science that studies of all aspects of the interactions between the immune system and nervous system. It deals with, among other things, the physiological functioning of the neuroimmune system in states of both health and disease; malfunctions of the neuroimmune system in disorders (autoimmune diseases, hypersensitivities, immune deficiency), the physical, chemical and physiological characteristics of the components of the neuroimmune system in vitro, in situ, and in vivo. Despite the brain''s status as an immune privileged site, an extensive bi-directional communication takes place between the nervous and the immune system in both health and disease. Immune cells and neuroimmune molecules such as cytokines, chemokines, and growth factors modulate brain function through multiple signalling pathways throughout the lifespan. Immunological, physiological and psychological stressors engage cytokines and other immune molecules as mediators of interactions with neuroendocrine, neuropeptide, and neurotransmitter systems. For example, brain cytokine levels increase following stress exposure, while treatments designed to alleviate stress reverse this effect. This book presents leading research from around the globe.

Book SynopsisMental retardation is a term used when a person has certain limitations in mental functioning and in skills such as communicating, taking care of him or herself, and social skills. These limitations will cause a child to learn and develop more slowly than a typical child. Children with mental retardation may take longer to learn to speak, walk, and take care of their personal needs such as dressing or eating. They are likely to have trouble learning in school. They will learn, but it will take them longer. There may be some things they cannot learn. The most common causes of mental retardation are: 1). Genetic conditions. Sometimes mental retardation is caused by abnormal genes inherited from parents, errors when genes combine, or other reasons. Examples of genetic conditions are Down syndrome, fragile X syndrome, and phenylketonuria (PKU). 2). Problems during pregnancy. Mental retardation can result when the baby does not develop inside the mother properly. For example, there may be a problem with the way the baby''s cells divide as it grows. A woman who drinks alcohol or gets an infection like rubella during pregnancy may also have a baby with mental retardation. 3) Problems at birth. If a baby has problems during labour and birth, such as not getting enough oxygen, he or she may have mental retardation. 4. Health problems. Diseases like whooping cough, the measles, or meningitis can cause mental retardation. Mental retardation can also be caused by extreme malnutrition (not eating right), not getting enough medical care, or by being exposed to poisons like lead or mercury. This book presents new and important research in the field.

Book SynopsisThis book presents the latest research on the sympathetic nervous system (SNS) which is a branch of the autonomic nervous system. It is always active at a basal level (called sympathetic tone) and becomes more active during times of stress. Its actions during the stress response comprise the fight-or-flight response. Like other parts of the nervous system, the sympathetic nervous system operates through a series of interconnected neurons. Sympathetic neurons are frequently considered part of the peripheral nervous system (PNS), although there are many that lie within the central nervous system (CNS). Sympathetic neurons of the spinal cord (which is part of the CNS) communicate with peripheral sympathetic neurons via a series of sympathetic ganglia. Within the ganglia, spinal cord sympathetic neurons join peripheral sympathetic neurons through chemical synapses. Spinal cord sympathetic neurons are therefore called presynaptic (or preganglionic) neurons, while peripheral sympathetic neurons are called postsynaptic (or postganglionic) neurons. At synapses within the sympathetic ganglia, preganglionic sympathetic neurons release acetylcholine, a chemical messenger that binds and activates nicotinic acetylcholine receptors on postganglionic neurons. In response to this stimulus, postganglionic neurons principally release noradrenaline (norepinephrine). Prolonged activation can elicit the release of adrenaline from the adrenal medulla. Once released, noradrenaline and adrenaline bind adrenergic receptors on peripheral tissues. Binding to adrenergic receptors causes the effects seen during the fight-or-flight response. These include pupil dilation, increased sweating, increased heart rate, and increased blood pressure.

Book SynopsisEndogenous neuoprotection is a phenomenon where a brief episode of ischemia renders the brain resistant against a subsequent longer-asting ischemia event. Experimentally, the author was able to model hypoxic preconditioning in animal model. Increasing knowledge of this endogenous neuroprotectin by ischemic tolerance may help to minimize neuronal damage following ischemic stroke and hypoxic encephalopathy. This book is, therefore, the first overview of this important topic and will certainly influence further investigations in clinical and neuroscience research.

Book SynopsisThis book presents important analyses of current issues in BSE (bovine spongiform encephalopathy or "mad cow disease") as a fatal neurological disease of cattle, believed to be transmitted mainly by feeding infected cattle parts back to cattle. More than 187,000 cases have been reported world-wide, 183,000 of them in the United Kingdom (UK) where BSE was first identified in 1986. The annual number of new cases has declined steeply since 1992. Humans who eat contaminated beef are believed susceptible to a rare but fatal brain wasting disease, variant Creutzfeldt-Jakob Disease (vCJD). About 160 people have been diagnosed with vCJD since 1986, most in the UK and none linked to any Canadian or U.S. meat consumption.

Book SynopsisSynaptic plasticity is the ability of the connection, or synapse, between two neurons to change in strength. There are several underlying mechanisms that co-operate to achieve synaptic plasticity, including changes in the quantity of neurotransmitter released into a synapse and changes in how effectively cells respond to those neurotransmitters. Since memories are postulated to be represented by vastly interconnected networks of synapses in the brain, synaptic plasticity is one of the important neurochemical foundations of learning and memory. In this book the discussion of synaptic plasticity that effects both physical and mental behaviour of organisms is discussed including as the physical performance of an organism that resulted in a stroke, drug addiction, or the mechanisms of brain plasticity that forms mental disorders such as depression.

Book SynopsisAlzheimer''s disease (AD) is characterized by the deposition into the brain of amyloid peptide, which originates a cascade of inflammatory events leading eventually to neuronal death. These pathological events likely occur several years before the clinical manifestation of the disease, implying that potential therapeutical interventions are currently started too late to give beneficial results. Recently, growing attention has been paid to the Mild Cognitive Impairment (MCI), considered the prodromal phase of AD, as 80% of subjects with MCI have been shown to develop AD within 5 years. Several studies aimed to identify biological markers to differentiate between normal aging and incipient AD have been carried out, including cerebrospinal fluid (CSF) analysis and neuroimaging. In particular, the evaluation of CSF Amyloid beta (1-42) levels, together with tau and phospotau, are of help for recognizing early AD. Besides, a number of additional molecules are altered in CSF. Other early modifications have been observed in peripheral cells, such as fibroblasts and leukocytes, as well as in serum from patients. Biomarkers for AD represent important tools supporting the clinical diagnosis and the choice of potential therapeutic options. Moreover, they would be of great help for the selection of cohorts of homogeneous patients for clinical trials with new disease-modifying compounds. This book is aimed to give an update about MCI as prodromal Alzheimer''s disease (AD), to discuss the main known pathological mechanisms at the basis of AD and to describe the possible biomarkers to be used for an early diagnosis of the disease.

Book SynopsisNeuroscience is the scientific study of the nervous system. The principle mechanism underlying enhanced pain sensitivity is a persistent hyperexcitability of spinal dorsal horn neurons. This book describes cellular mechanisms for the maintained hyperexcitability of spinal dorsal horn neurons mediated by neuron-glia interactions following spinal cord injury. In addition, nerve growth factor (NGF) has a key role not only in the development of sensory and autonomic neurons, but also in the processes of nociception. This book examines the recent evidence of the involvement of NGF in painful diseases and suggests the potential usefulness of anti-NGF strategies as novel analgesics for disabling pathological conditions. Furthermore, neuralgia is a symptom of some neurological disorders and can be found at any age. The pain that accompanies it is usually brief but may be severe. The authors present evidence sustaining the hypothesis that neuralgia (understood as being a shooting/shock-like paroxysmal pain) is a clinical expression of a transcriptional channelopathy. Other chapters in this book review the underlying mechanisms and the anatomical loci/shared circuits between epilepsy and memory, along with the relationship of various neurotransmitters involved. The morphological and functional characteristics of hereditary choroidal dystrophies are also examined, as well as the potential implications of neuroplasticity in dorsal vagal complex (DVC) in the adaptation of gastrointestinal functions.

Book SynopsisIntellectual disabilities have been related to the dysfunction of the prefrontal cortex. The prefrontal cortex is located on the anterior part of the frontal lobes of the brain, lying in front of the motor and premotor areas. This brain region has been implicated in planning complex cognitive behaviours, personality expression, and moderating correct social behaviour. This book presents a review of present day evidence of the reduction of the prefrontal cortex; links between abnormalities and functional or clinical features of intellectual disabilities such as schizophrenia. The book presents the latest research from around the world in this field.

Book SynopsisOur intelligent life deeply depends on the highly evolved nervous system of the brain, and the brain is one of most exciting themes in science. The authors have studied the control mechanism of the central nervous system in masticatory movements using electromyograms (EMG), electroencephalograms (EEG), and magnetoencephalograms (MEG). Much of the volume of this book is made up of descriptions of common established knowledge in neurophysiology, whereas short columns, entitled "A Different Angle", are interspersed here and there in each chapter. "A Different Angle" columns were based on students'' questions. Many readers of this book may have had questions like those described in "A Different Angle" at an early stage of their study of neuroscience, but which may have been forgotten. Everybody, including specialists in neuroscience, will be able to read and use this book to gain a better understanding of the field.

Book SynopsisBehavioural interventions for Autistic Spectrum Disorders (ASD) are among the most widely used approaches, and have proved both extremely popular with parents, and controversial with professionals. These behavioural techniques are some of the few practical applications of psychology in this area to be scientifically evaluated and validated, and this availability of evidence allows both their strengths and weaknesses to be debated. Much of this debate has focused on the initial claims made about these behavioural approaches two decades ago, and the scientific evidence following these initial claims often does not enter into the debate. However, there have been enormous developments and diversifications in the approaches offered by behavioural psychologists to the treatment of ASD, and this text now brings together new evidence regarding these contemporary developments in one place, offering an essential handbook of contemporary behavioural practice for ASD, provided by the key researchers in the field. This book provides detailed empirically-based reviews of many of the behavioural interventions that are used to help children and adults with ASD, and these chapters are organised into three sections for easy reference.

Book SynopsisNeuroanatomy is the study of the anatomical organisation of the brain. Reciprocal communication between the brain and the cardiovascular system is important in sustaining neurobehavioral states that allow organisms to cope with their environment. Furthermore, in vertebrate animals, the routes that the myriad nerves take from the brain to the rest of the body, and the internal structure of the brain in particular, are both extremely elaborate. As a result, the study of neuroanatomy has developed into a discipline in itself, although it also represents a specialisation within neuroscience. This book briefly covers the neuroanatomy of the vagal circuit, the functional significance of tonic cardiac vagal function and ways of quantifying this measure for research purposes. Also examined are the fibre composition and functional topography of peripheral nerves, and innovative methodologies that facilitate measurements of nerve fibres. This book contributes new insights to the controversial discussion about neurotrophin effects on different cell populations and at different time points in retinal programmed cell death (PCD). Other chapters in this book provide a comparative overview of the distribution of orexin cells and fibres across the brains of vertebrates in relation to function, the neuroanatomical structures and autonomic nerves involved in headaches and a re-evaluation of the structure of the human anterior olfactory nucleus, with an updated description of this structure in the normal human.

Book SynopsisThis book aims at providing an overview and in depth analysis of recent developments in stem cell research and therapy. It is composed of recently published review articles that went through peer-review process. Stem cells are the building blocks of the body. They can develop into any of the cells that make up our bodies. Stem cells hold a great deal of hope for the treatment of a broad range of diseases and injuries, spanning from cancers, diabetes, genetic diseases, graft-versus-host disease, eye, heart and liver diseases, inflammatory and autoimmune disorders, to neurological diseases and injuries, particularly neurodegenerative diseases. These include Alzheimer''s and Parkinson''s diseases, cerebral strokes, and traumatic brain and spinal cord injuries. Therefore, Stem cell research is as important for the understanding of the physio- and pathology of the body, as well as for the development and therapy, including the nervous system. Volume IV provides an overview and in depth analysis of recent developments on the role and functions of newly generated neuronal cells of the adult brain in the physio- and pathology of the nervous system. It further emphasises the tremendous potential of adult neural stem cells, as a promising model, for cellular therapy and regenerative medicine.

Book SynopsisIntracranial hypertension (ICH) is the most common cause of clinical deterioration and death for neurological and neurosurgical patients. There are a lot of causes of raised intracranial pressure (ICP) and increased ICP can produce intracranial hypertension syndromes. Monitoring of intracranial pressure and advances in investigations of the central nervous system have led to new concepts and systemisations in intracranial hypertension.The descriptive classification of the intracranial hypertension has been replaced by an etio-pathogenic classification with four main groups: 1. Parenchymatous Intracranial Hypertension, in the extending intracranial processes (cerebral tumours, intracranial haematoma, cerebral abscesses, etc.), in traumatic brain edema, in hypotoxic brain edema, in general intoxications with neurotoxins (endogenous or exogenous), etc.; 2.Vascular Intracranial Hypertension, caused by the disorders of cerebral blood circulation and then the brain edema or / and brain swelling appears. The vascular intracranial hypertension occurs in : I. -- vascular cerebral diseases : cerebral venous thrombosis or in in cerebral ischaemic stroke and in II. -- extracerebral vascular diseases as hypertensive encephalopathies; 3. Intracranial Hypertension caused by the Disorders of the CSF dynamics ( hydrocephalus etc); 4.Idiopathic Intracranial Hypertension. The treatment of intracranial hypertension depends on the type of intracranial hypertension and on the stage of the illness.

Book SynopsisAlzheimer''s disease (AD), the most common form of neurodegenerative disorder in the elderly, is characterised pathologically by extracellular amyloid plaques and intracellular neurofibrillary tangles, pathophysiologically by synaptic dysfunction, and clinically by a progressive decline in cognition. Currently, AD has no cure and its prevalence is predicted to triple by 2050 with the rapid increase in the ageing population, unless more effective prevention/treatments are developed. Since the publication of the third book volume, the rapid progress in the research fields of AD and dementia continues through the intensive efforts of research scientists world-wide. This fourth book volume contains 12 chapters, bringing together a presentation of scientific frontiers in current AD/dementia research. The topics include emotional memory in AD, amyloid-B clearance, synaptic transmission-mediated regulation of amyloid-B dynamics, anti-AD immunotherapy, clinical trials of AD therapeutics using AD transgenic mouse models, roles of apolipoprotein E, chronic inflammation, cathepsins, and gelsolin in AD pathogenesis and as anti-AD therapeutic targets/agents, declarative memory impairment and hippocampal atrophy in Parkinson''s disease, fronto-temporal dementia, and cognitive impairment in schizophrenia. These chapters cover current advances in our understanding of the pathogenic mechanisms underlying AD and dementia, in the diagnosis of early AD and dementia, and in the development of therapeutic agents that target memory-relevant AD pathogenesis. The book will be highly valuable to students and scientists world-wide who are interested in the scientific research progress in AD and memory disorders.

Book SynopsisMild cognitive impairment, also known as incipient dementia, or isolated memory impairment, is a diagnosis given to individuals who have cognitive impairments beyond that expected for their age and education, but that do not interfere significantly with their daily activities. It is considered to be the boundary or transitional stage between normal ageing and dementia. Although MCI can present with a variety of symptoms, when memory loss is the predominant symptom it is termed "amnestic MCI" and is frequently seen as a risk factor for Alzheimer''s disease. Studies suggest that these individuals tend to progress to probable Alzheimer''s disease at a rate of approximately 10% to 15% per year. Additionally, when individuals have impairments in domains other than memory it is classified as non-amnestic single- or multiple-domain MCI and these individuals are believed to be more likely to convert to other dementias. This book gathers the latest research from around the globe in this field and highlights related topics such as: cognitive aspects in epilepsy, cognitive impairment in children with ADHD, therapies for Alzheimer''s disease, foetal alcohol spectrum disorders, and others.

Book SynopsisA peculiar feature of the mammalian hippocampus is that it maintains the ability to generate new neurons throughout adult life while most other areas of the brain do not. In this book, we outline evidence for the functional consequences of adult neurogenesis in the dentate gyrus highlighting a possible role in learning and memory and depression. Presynaptic modulation at the MF synapse is also described with respect to its involvement in the activity-dependent nature of the MF synapse and contribution to physiological functions of MFs. In addition, the hippocampus is one of the first and most affected brain regions impacted by both Alzheimer''s disease and mild cognitive impairment. This book discusses such negative consequences of aging and diseases which may be prevented or reversed by physical exercise, which has been associated with improved hippocampul-dependent learning and memory and executive functioning. The functional status of hippocampal cholinergic terminals was also assessed in order to determine if an early beginning of ethanol consumption at moderate doses disrupts acetylcholine release in animals non selected by ethanol preference.

Book SynopsisThis book reviews behavioural and neuroimaging evidence that has revealed effects of emotion on memory and attention in individuals with and without post-traumatic stress disorder (PTSD). The authors also review the historical development of memory reconsolidation, discuss some of the important behavioural characteristics and potential mechanisms of memory reconsolidation, and consider the possible implications of this research for treatment of psychiatric conditions such as PTSD, phobias and drug addiction. Moreover, assessment of cognitive, motor, sensory and communicative functions in children with profound intellectual and multiple disabilities (PIMD) is still in its infancy. The characteristics of children PIMD are described in this book. The importance of alertness in assessment, both as a mean and as an objective, is then explained. The implications of such a complex pattern of disabilities for assessment of alertness is considered as well. In this book, the authors also examine the effects of age and knowledge of memory ageing on subjective appraisals of memory in forgetful others using a person perception paradigm. The social/communication features that differentiate intellectual disabilities of three different aetiologies: Low Functioning Autism, Down Syndrome and Idiopathic Intellectual Disability are explored as well. Other chapters review evidence about laboratory-based and environment-based research on spatial memory, the influence of music on various forms of memory, and evidence from literature that working memory is a major component of successful performance on an IQ test. Impairment is discussed in working memory in ID, which could also affect problem solving abilities on a non-verbally based measure, such as the Raven''s Coloured Progressive Matrices (RCPM).
