Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and invaluable, Huntington's Disease aims to help scientists to significantly extend the breadth and quality of research in laboratories dedicated to mastering and controlling this devastating human condition.

This well-written text thoroughly addresses two quality of life issues in patients with a variety of neurological disorders: sexual and reproductive function. The de vasta stating effects of a variety of neurological diseases are well known to both the lay and medical communitIes, and are treated in numerous texts. However, as we continue to experience therapeutic breakthroughs in the tields of neurology and rehabilitation medicine, physicians and patients must become more aware of the issues discussed in this text. It is particularly important, as emphasized throughout the chapters, that the physician or therapist initiate conversations with the patients concerning both the possibility of parenting a child, as well as the ability of the patient to enhance his/her sexual functioning. Commonly in the patient who is otherwise perfectly normal, there is a reluctance to discuss these topics and couples often feel embarrassed to initiate a conversation with their physi cians. This reluctance to initiate a discussion is even more apparent in patients with a variety of neurological disorders, in which there are overriding fears concerning both function and survival, as well as deep concerns about their own attractiveness, and their sexual and repro ductive ability."

The discovery of adult neurogenesis caused a paradigm shift in the neurosciences. For more than 100 years, it was believed that adult neurons do not regenerate. Joseph Altman and Fernando Nottebohm found proof to the contrary and changed the course of history. Their research, included here, provides the foundations of the field. Today, adult neurogenesis is a rapidly expanding discipline applicable to the study of brain development and diseases, learning and memory, aging, and neuropsychiatric disorders. With multiple authors, the 27 chapters of this book contain the latest work in two volumes. The first presents the basic biology of adult neurogenesis in non-mammalian vertebrates and in the mammalian hippocampus and olfactory bulb, and the second discusses clinical implications and delves into adult neurogenesis and brain injury as well as neurodegenerative and neuropsychiatric pathologies. With details of the anatomy, physiology, and molecular biology of the two neurogenic brain regions, this book provides indispensable knowledge for many areas of neuroscience and for experimental and clinical applications of adult neurogenesis to brain therapy.

The symposium from which this book originates represents a sig nificant watershed in the field of intraoperative neural monitoring, since the participants concluded that electrophysiologic monitoring techniques should be considered a "standard of care" for surgical pro cedures that place the central nervous system (CNS) at risk for injury. Specifically, it was agreed that the somatosensory-evoked potential (SEP) is a remarkably reliable and sensitive indicator of several aspects of CNS function, and should be routinely employed as an intraopera tive monitor during many neurosurgical and orthopedic procedures. The significance of this conclusion cannot be overstated, for at the time of this writing, intraoperative monitoring methods based on evoked-potential analyses are still considered experimental and are not in routine use. The reasons for this are not clear, given the accu mulation of literature and expertise on this subject over the past five years. Granted, the cost of electrophysiological monitoring equip ment is high, but only initially. The benefits of injury prevention far outweigh these costs, from both medical and economic viewpoints. It is our sincere hope and goal that the medical community be made aware of the value of intraoperative neural monitoring."

INTEGRATED NEUROSCIENCES This textbook takes as a premise that, in order to make intelligent diagnosis and provide a rational treatment in disorders of the nervous system, it is necessary to develop the capacity to answer the basic questions of clinical neurology: (1) Where is the disease process located? (2) What is the nature of the disease process? The purpose of this textbook is to enable the medical student to acquire the basic information of the neurosciences and neurology and most importantly the ability to apply that information to the solution of clinical problems. The authors also suggest that hospital trips be a part of any Clinical Neurosciences Course so that the student can put into actual practice what he has learned in the classroom. We believe that this textbook will be of value to the student throughout the four years of the medical school curriculum. Medical, psychiatry and neurology residents may also find this text of value as an introduction or review. It is more true in neurology than in any other system of medicine that a firm knowledge of basic science material, that is, the anatomy, physiology and pathology of the nervous system, enables the student and physician to readily arrive at the diagnosis of where the disease process is located and the nature of the most likely pathology. Subsequently that knowledge may be applied to problem solving in clinical situations.

This volume focuses on the relationship between the nervous and the immune system with regard to the effects of drugs of abuse and infections, including infection caused by the immunodeficiency virus which causes AIDS, the number one health problem worldwide. Chapters focus on the brain-immune axis, detailing the effects of drugs of abuse. It is well known that recreational drugs of abuse such as morphine, cocaine, and marijuana, as well as other drugs, including the legal drugs alcohol and nicotine, are used by large numbers of individuals. Serious concerns have been raised about the consequences of using such drugs, especially in relation to their effects on normal physiological responses, including immune mechanisms. It is now widely recognized not only that many drugs of abuse have serious consequences on normal parameters of neurologic and neuroendocrine systems in general but also that effects on those systems, in turn, may affect indirectly immunity and also directly affect immune systems. Much data has now been accumulated showing that drugs of abuse markedly alter the immune response in human populations as well as in experimental animals, both in vivo and in vitro. Furthermore, studies on microbial infections have shown that many drugs of abuse are associated with increased susceptibility to infectious diseases, especially opportunistic intracellular microorganisms, including viruses such as HIV which causes AIDS. The mechanisms whereby drugs of abuse increase the likelihood of infections by opportunistic microorganisms in humans as well as in experimental animals are delineated. This volume will further the understanding of the impact of drugs of abuse on the brain-immuneaxis and its relationship to immunomodulation and infection, especially that caused by the AIDS virus.

This book is a rich source of information on biomarkers applicable to the pathology of neoplastic disorders of the brain. Thorough descriptions are provided of the techniques currently available for clinical and experimental evaluation of biomarkers in brain neoplasms, including in situ hybridization, array-based methods, methylation profiling, next-generation sequencing, and practical gene panels. Incorporation of multiple biomarkers in the development of molecular subgroups with biologic and therapeutic relevance is also discussed. A section on biobanking covers the equally important topic of optimal preservation of tissue and includes consideration of ethical considerations raised by the use of tissue obtained in clinical settings. The closing section discusses the major categories of neoplastic disorders involving the nervous system, with emphasis on diagnostic, prognostic, and predictive biomarkers used in the pathologic evaluation of different types of brain tumor.

The aim of this book is to publicise and bring to a wider audience the concept that the cause of two neurological diseases, namely multiple sclerosis (MS) and "mad cow disease" also known as "bovine spongiform encephalopathy" are related through exposure to a common microbe Acinetobacter which is found in human sinuses, on skin and in the soil. An infection is the cause of a neurological disease in man and in animals. Elevated levels of antibodies to Acinetobacter have been found in multiple sclerosis patients as well as in ruminants who have been described as suffering from "mad cow disease" following exposure to contaminated feed supplements. The overall objective and scope of this book is to inform the audience, the reader, that multiple sclerosis may be linked to a microbe Acinetobacter which carries molecular structures resembling myelin, the outer sheath covering of neurons.

Cognitive science is a multidisciplinary science concerned with understanding and utilizing models of cognition. It has spawned a great dealof research on applications such as expert systems and intelligent tutoring systems, and has interacted closely with psychological research. However, it is generally accepted that it is difficult to apply cognitive-scientific models to medical training and practice. This book is based on a NATO Advanced Research Workshop held in Italy in 1991, the purpose of which was to examine the impact ofmodels of cognition on medical training and practice and to outline future research programmes relating cognition and education, and in particular to consider the potential impact of cognitive science on medical training and practice. A major discovery presented in the book is that the research areas related to artificial intelligence, cognitive psychology, and medical decision making are considerably closer, both conceptually and theoretically, than many of the workshop participants originally thought.

The purpose of the book is to advance in the understanding of brain function by defining a general framework for representation based on category theory. The idea is to bring this mathematical formalism into the domain of neural representation of physical spaces, setting the basis for a theory of mental representation, able to relate empirical findings, uniting them into a sound theoretical corpus.

The innovative approach presented in the book provides a horizon of interdisciplinary collaboration that aims to set up a common agenda that synthesizes mathematical formalization and empirical procedures in a systemic way. Category theory has been successfully applied to qualitative analysis, mainly in theoretical computer science to deal with programming language semantics. Nevertheless, the potential of category theoretic tools for quantitative analysis of networks has not been tackled so far. Statistical methods to investigate graph structure typically rely on network parameters. Category theory can be seen as an abstraction of graph theory. Thus, new categorical properties can be added into network analysis and graph theoretic constructs can be accordingly extended in more fundamental basis. By generalizing networks using category theory we can address questions and elaborate answers in a more fundamental way without waiving graph theoretic tools. The vital issue is to establish a new framework for quantitative analysis of networks using the theory of categories, in which computational neuroscientists and network theorists may tackle in more efficient ways the dynamics of brain cognitive networks.

The intended audience of the book is researchers who wish to explore the validity of mathematical principles in the understanding of cognitive systems. All the actors in cognitive science: philosophers, engineers, neurobiologists, cognitive psychologists, computer scientists etc. are akin to discover along its pages new unforeseen connections through the development of concepts and formal theories described in the book. Practitioners of both pure and applied mathematics e.g., network theorists, will be delighted with the mapping of abstract mathematical concepts in the terra incognita of cognition.

How do you build a life when all that you know is changing?

How do you conceive of love when you can no longer recognise those who mean the most to you?

A phenomenal memoir - the first of its kind - Somebody I Used to Know is both a heart-rending tribute to the woman Wendy Mitchell once was, and a brave affirmation of the woman dementia has seen her become.

In Neuroprotective Signal Transduction prominent researchers and clinicians focus on how inter- and intracellular signaling mechanisms prevent the degeneration and death of neurons occurring in both acute and chronic neurodegenerative disorders. Authoritative contributions dissect the signaling pathways of an array of neuroprotective factors-ranging from neurotrophins (NGF, BDNF, NT-3, and NT-4/5), to growth factors (bFGF, IGF-1, GDNF), to cytokines (TNF, IL-1b, and TGFb), to secreted amyloid precursor proteins, to protease nexin-1. Also treated are cytoprotective signaling events that occur within injured neurons independently of intercellular signals. Neuroprotective Signal Transduction presents fundamental, cutting-edge treatment of the cellular and molecular signal transduction pathways found in human neurodegenerative conditions. The book's elucidation of the molecular cascades evolved by the nervous system to protect itself is now lead to effective strategies for preventing neuronal degeneration in such conditions as stroke, traumatic brain injury, Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis, and will form the basis for powerful new drug discovery and gene therapy strategies.

Understanding the biology of brain function is a great challenge and a major goal of modern science. The brain is one of the last great frontiers in science, and the unraveling of its mysteries is comparable in complexity to efforts in space exploration. A fundamental goal of neuroscience is to understand how neurons generate behavior and the pathophysiology of different mental and neurological diseases. The aim of this book is to describe recent discoveries about the basic operations of the brain and to provide an introduction to the adaptations for specific types of information processing.

This volume represents the proceedings of a NATO Advanced Study Institute (ASI) on the topic of "Motor Neuroscience" held at the Hotel San 15-24, 1990. The San Bastiano Hotel Bastiano, Calcatoggio (Corsica), September provided a beautiful setting for the ten day ASI in aresort on the west coast of Corsica, near the island's capital city of Ajaccio. The motivation of this ASI originated from the success of an ASI that we organized eleven years ago at Senanque Abbey in the south of France. Our earlier meeting was successful in providing some coherence to a widely scattered literature while providing up to date knowledge on motor control and learning. Our goal for the second ASI was essentially the same. We wanted to appraise the main theoretical ideas that currently characterize the field by bringing together many of the internationally known scientists who are doing much of the contemporary work. It is our hope that these proceedings will provide some conceptual unification to an expanding and diverse literature on motor control.

A "brain defibrillator" may be closer than we think. An epileptic seizure involves a paroxysmal change in the activity of millions of neurons. Feedback control of seizures would require an implantable device that could predict seizure occurrence and then deliver a stimulus to abort it. To examine the feasibility of building such a device, this text brings together experts in epilepsy, bio-engineering, and dynamical systems theory. Topics include the development of epileptic systems, seizure prediction, neural synchronization, wave phenomena in excitable media, and the control of complex neural dynamics using brief electrical stimuli.

Injury of the spinal cord has been known since antiquity. There is no cure for the injury and until modern times patients died rapidly from a combination of pressure sores and urinary tract infection. Treatment consists of preventing complications until the spine has stabilised and the patient can be rehabilitated to an independent life. "History of the Treatment of Spinal Injuries" explores how this treatment developed in the Ancient World, the Middle Ages, in Europe, Great Britain and latterly in the United States. It describes how these principles of treatment were recognised and explores the relationship and rivalry of the powerful personalities of the doctors who developed this treatment against the social background at different times.

Dr Daniel Gibbs is one of 50 million people worldwide with an Alzheimer's disease diagnosis. Unlike most patients with Alzheimer's, however, Dr Gibbs worked as a neurologist for twenty-five years, caring for patients with the very disease now affecting him. Also unusual is that Dr Gibbs had begun to suspect he had Alzheimer's several years before any official diagnosis could be made. Forewarned by genetic testing showing he carried alleles that increased the risk of developing the disease, he noticed symptoms of mild cognitive impairment long before any tests would have alerted him. In this highly personal account, Dr Gibbs documents the effect his diagnosis has had on his life and explains his advocacy for improving early recognition of Alzheimer's. Weaving clinical knowledge from decades caring for dementia patients with his personal experience of the disease, this is an optimistic tale of one man's journey with early-stage Alzheimer's disease.
