This volume brings together various theories of how aberrations in mitochondrial function and morphology contribute to neurodegeneration in idiopathic and familial forms of Parkinson's disease. Moreover, it comprehensively reviews the current search for therapies, and proposes how molecules are involved in specific functions as attractive therapeutic targets. It is expected to facilitate critical thought and discussion about the fundamental aspects of neurodegeneration in Parkinson's disease and foster the development of therapeutic strategies among researchers and graduate students. Theories of idiopathic Parkinson's etiology support roles for chronic inflammation and exposure to heavy metals or pesticides. Interestingly, as this project proposes, a case can be made that abnormalities in mitochondrial morphology and function are at the core of each of these theories. In fact, the most common approach to the generation of animal and cell-culture models of idiopathic Parkinson's disease involves exposure to mitochondrial toxins. Even more compelling is the fact that most familial patients harbor genetic mutations that cause disruptions in normal mitochondrial morphology and function. While there remains to be no effective treatment for Parkinson's disease, efforts to postpone, prevent and "cure" onset mitochondrial aberrations and neurodegeneration associated with Parkinson's disease in various models are encouraging. While only about ten percent of Parkinson's patients inherit disease-causing mutations, discovering common mechanisms by which familial forms of Parkinson's disease manifest will likely shed light on the pathophysiology of the more common idiopathic form and provide insight to the general process of neurodegeneration, thus revealing therapeutic targets that will become more and more accessible as technology improves.
After a little more than 20 years since the original discovery of neuropeptide Y (NPY) by Tatemoto and colleagues, the field of NPY research has made remarkable progress and is coming of age.The present volume addresses all major topics in connection with NPY and related peptides by established leaders in their respective areas. Experienced NPY-aficionados will certainly find new and useful additional information in this volume and newcomers to the field will hopefully discover how much exciting research this still has to offer.
Well known experts in the field of Chronobiology from around the world, provide an integrative view of the state of the art of circadian biology. At present, genetic and epigenetic interaction of regulatory pathways among circadian oscillators, metabolic networks, cellular differentiation and neuronal communication are subject of intense scrutiny. The book is organized in three sections: The first includes selected examples of the circadian systems of crustaceans, insects, fish, birds and mammals. The second is a detailed view of the physiological mechanisms underlying the circadian clocks in mammals. Finally, in the third section some examples of the relevance of circadian biology and circadian misalignment to health and disease are provided including nutrition and metabolism, obesity, cancer, cardiovascular and pulmonary diseases, Huntington and affective diseases. This section concludes with a brief review on gene therapy and its potential use as a therapeutic tool to correct "clock genes" pathologies. This book is aimed at all those interested in contemporary aspects of physiology, biochemistry and molecular biology applied to the study and characterization of timing systems.. It could be used as an initial approach to this field, but it also provides updated information for those already familiar with the fascinating field of Chronobiology.
It can be reasonably anticipated that, over the next generations, the proportion of elderly people will remarkably increase and, with this, the number ofpersons suffering from acute (e.g. cerebral ischemia) or chronic neurodegenerative disorders. To date, approved drugs only alleviate the symptoms ofthese diseases (for instance, acetylcholinesterase inhibitors in Alzheimer disease and L-dopa and dopamine-agonists in Parkinson disease), while none seems to stop the progression of the degenerative processes underlying them. The development of effective preventive or protective therapies has been impeded by the limitations of our knowledge of the causes and the mechanisms by which neurons die in neurodegenerative disorders. Evidence accumulated in the past 20 years indicated that the major excitatory neurotransmitter glutamate may play a role as neurotoxin in several conditions. In particular, the glutamatergic system dysfunction seems to be an early event working as a common pathway in the pathogenesis ofa large number ofacute and chronic neurological disorders, in strict conjunction with other important mechanisms, such as oxidative stress and energetic failure, and probably triggered by different mechanisms in various diseases. In consideration of that, drug discovery efforts over the last decade have been focused on the search for drugs that either reduce glutamate synaptic levels or block its postsynaptic effects. Despite numerous reviews on basic mechanisms and clinical aspects ofthe excitotoxic phenomenon, so far no comprehensive book has covered the topic in all its complexity, starting from basic pharmacological mechanisms, to .animal models of diseases and finally to clinical pathogenic and therapeutic implications.
This collection of contributions on the subject of the neural mechanisms of sensorimotor control resulted from a conference held in Cairns, Australia, September 3-6, 2001. While the three of us were attending the International Union of Physiological Sciences (IUPS) Congress in St Petersburg, Russia, in 1997, we discussed the implications of the next Congress being awarded to New Zealand. We agreed to organise a satellite to this congress in an area of mutual interest -the neuroscience of movement and sensation. Australia has a long-standing and enviable reputation in the field of neural mechanisms of sensorimotor control. Arguably this reached its peak with the award of a Nobel Prize to Sir John Eccles in 1963 for his work on synaptic transmission in the central nervous system. Since that time, the subject of neuroscience has progressed considerably. One advance is the exploitation of knowledge acquired from animal experiments to studies on conscious human subjects. In this development, Australians have achieved international prominence, particularly in the areas of kinaesthesia and movement control. This bias is evident in the choice of subject matter for the conference and, subsequently, this book. It was also decided to assign a whole section to muscle mechanics, a subject that is often left out altogether from conferences on motor control. Cairns is a lovely city and September is a good time to visit it.
It is now widely recognised that biological psychiatry is rapidly
coming into its own. For over the last three decades dramatic
advances in this young discipline have been made, all of which
attest to the staying power of the experimental method. Those who
made this revolution in knowledge happen are a breed of
investigators availing themselves of the tools of molecular
biology, pharmacology, genetics, and perhaps, above all, the
technology of neuroimaging. The introduction of the
interdisciplinary method of approach to the study of
psychopathology had made it very clear that neuroimaging, as a set
of techniques, is unique in that it is gradually providing us with
evidence supporting Kraepelin's original view that mental illness
is closely associated with abnormal changes in the brain.
The idea of a disjunctive theory of visual experiences first found expression in J.M. Hinton's pioneering 1973 book Experiences. In the first monograph in this exciting area since then, William Fish develops a comprehensive disjunctive theory, incorporating detailed accounts of the three core kinds of visual experience--perception, hallucination, and illusion--and an explanation of how perception and hallucination could be indiscriminable from one another without having anything in common. In the veridical case, Fish contends that the perception of a particular state of affairs involves the subject's being acquainted with that state of affairs, and that it is the subject's standing in this acquaintance relation that makes the experience possess a phenomenal character. Fish argues that when we hallucinate, we are having an experience that, while lacking phenomenal character, is mistakenly supposed by the subject to possess it. Fish then shows how this approach to visual experience is compatible with empirical research into the workings of the brain and concludes by extending this treatment to cover the many different types of illusion that we can be subject to.
Nearly, 50 years ago, Karl Pribram in a discussion section accompanying MacLean's proposal of a limbic system, criticized the visceral or limbic brain concept as theoretically too vague and cumbersome. In a recent review of the limbic system, Swanson points to Brodal's criticism that the discovery of connections of limbic structures with virtually all parts of the nervous system render the concept of the limbic system useless, and better abandoned. Additional dissatisfaction surrounding the limbic brain concept stems from the feeling that it is historically inert (an antiquated 19th century construct). In our current age of neural networks, and parallel distributed process it is of little value, merely an historical curio. So why then this int- duction to limbic brain anatomy? We offer several interrelated rationales behind our labors. Recapitulation in the Service of Education: Although concepts had evolved in the second half of this century which effectively overthrew the idea of relatively isolated hemispheric districts (i. e. striatal, cortical, and limbic), parsing the hemisphere into these three districts was an important preliminary step achieved by our forebears in their efforts to understand the large scale structure of the higher mammalian cerebral hemisphere. An examination of how the limbic brain concept came to be provides an opp- tunity to recapitulate the process of exploration, discovery, and und- standing as it relates to one of these principle hemispheric domains.
Over the past decade, we have made great advances in the field of multiple sclerosis (MS) research, and this book focuses on those advances in MS pathogenesis and treatment. While some of these advances have been through new approaches and ideas that have emerged in the last decade such as the newly identified protective role that amyloid proteins may play in MS or the use of helminths to treat autoimmune diseases, others have evolved from previous theories and ideas that have only now gained momentum and a deeper understanding such as the role of HLA or gender in MS susceptibility. This book covers these emerging and evolving topics and highlights the substantial advancements made in elucidation of the factors regulating susceptibility or disease progression, identification of new ways to monitor or predict MS pathology, and development of new strategies for treating MS.
This volume is the second in the planned coverage of the
neurochemical circuitry of the primate central nervous system.
While this volume contains only two chapters, their topics and the
extraordinarily comprehensive coverage with which the authors have
dealt with their topics, will nevertheless contribute equal amounts
of knowledge, wisdom, and opportunities for future research
extensions as have every volume in this unique series. As such,
these chapters extend the goals of this primate series to develop a
broad coverage of human and non-human primate chemical
neuroanatomic details in a volume which makes clear the known and
desirable appreciation for differences between and among subsets of
primate brains.
The present work is the third in a series constituting an extension of my doctoral thesis done at Stanford in the early 1970s. Like the earlier works, The Reciprocal Modular Brain in Economics and Politics, Shaping the Rational and Moral Basis of Organization, Exchange, and Choice (Kluwer AcademicfPlenum Publishing, 1999) and Toward Consilience: The Bioneurological Basis of Behavior, Thought, Experience, and Language (Kluwer AcademicfPlenum Publishing, 2000), it may also be considered to respond to the call for consilience by Edward O. Wilson. I agree with Wilson that there is a pressing need in the sciences today for the unification of the social with the natural sciences. I consider the present work to proceed from the perspective of behavioral ecology, specifically a subfield which I choose to call interpersonal behavioral ecology. Ecology, as a general field, has emerged in the last quarter of the 20th century as a major theme of concern as we have become increasingly aware that we must preserve the planet whose limited resources we share with all other earthly creatures. Interpersonal behavioral ecology, however, focuses not on the physical environment, but upon our social environment. It concerns our interpersonal behavioral interactions at all levels, from simple dyadic one-to-one personal interactions to our larger, even global, social, economic, and political interactions.
When we began to organize the workshop "Calcium and Cellular Metabolism: Transport and Regulation" the goal we had in mind was to put together the knowledge of 2 several specialists on Ca + homeostasis, with various examples of cellular metabolisms 2 2 (such as protein synthesis), regulated by Ca + ions. Regarding the homeostasis of Ca + ions, we invited Ernesto Carafoli to write the first chapter as a general state-of-the-art introductory review. On the other hand, the other chapters are the contribution of different specialists on membrane calcium transport mechanisms, aiming to reunite at least in part the wide field of calcium homeostasis. We roughly try to group chapters that share similar subjects. The first group of chapters (Chapters 2 to 6), are mainly related to calcium channels. Thus, Chapter 2 by Rodolfo Llimis et a . describes a new concept related to the dimen sions of the calcium action domain at the inner mouth of calcium channels in the squid gi ant synapse and its relationship to neurotransmitter release. Chapter 3 by Martin Morad et a . informs us about new ways of identifying and measuring, by confocal microscopy, in dividual sites where calcium release occurs in ventricular myocytes. In the same group Osvaldo Uchitel and Eleonora Katz classify and evaluate the variety of calcium channels at the neuromuscular junction, in Chapter 4. Chapter 5 by Gustavo Brum et a ."
This introductory text lays particular emphasis on the relationship between development and behaviour. Indeed, the second part of the book is devoted to examining the role of factors present during development which influence the growth of the nervous system and subsequent behaviour. Throughout the subject matter is extensively illustrated in clear, colour diagrams, and each chapter ends with learning objectives and questions.
The ?eld of cellular responses to DNA damage has attained widespread recognition and interest in recent years commensurate with its fundamental role in the ma- tenance of genomic stability. These responses, which are essential to preventing cellular death or malignant transformation, are organized into a sophisticated s- tem designated the "DNA damage response". This system operates in all living organisms to maintain genomic stability in the face of constant attacks on the DNA from a variety of endogenous by-products of normal metabolism, as well as exogenous agents such as radiation and toxic chemicals in the environment. The response repairs DNA damage via an intricate cellular signal transduction network that coordinates with various processes such as regulation of DNA replication, tr- scriptional responses, and temporary cell cycle arrest to allow the repair to take place. Defects in this system result in severe genetic disorders involving tissue degeneration, sensitivity to speci?c damaging agents, immunode?ciency, genomic instability, cancer predisposition and premature aging. The ?nding that many of the crucial players involved in DNA damage response are structurally and functionally conserved in different species spurred discoveries of new players through similar analyses in yeast and mammals. We now understand the chain of events that leads to instantaneous activation of the massive cellular responses to DNA lesions. This book summarizes several new concepts in this rapidly evolving ?eld, and the advances in our understanding of the complex network of processes that respond to DNA damage.
Does the brain create the mind, or is some external entity
involved? In addressing this "hard problem" of consciousness, we
face a central human challenge: what do we really know and how do
we know it? Tentative answers in this book follow from a synthesis
of profound ideas, borrowed from philosophy, religion, politics,
economics, neuroscience, physics, mathematics, and cosmology, the
knowledge structures supporting our meager grasps of reality. This
search for new links in the web of human knowledge extends in many
directions: the "shadows" of our thought processes revealed by
brain imagining, brains treated as complex adaptive systems that
reveal fractal-like behavior in the brain's nested hierarchy,
resonant interactions facilitating functional connections in brain
tissue, probability and entropy as measures of human ignorance,
fundamental limits on human knowledge, and the central role played
by information in both brains and physical systems.
There are more than 100 billion brain cells in our heads, and every single one represents a fragment of thought and feeling. And yet each cell is a mystery of beauty, with branching, intricate patterns like shattered glass. Richard Wingate has been scrutinizing them for decades, yet he is still moved when he looks at one through a microscope and traces their shape by hand. With absorbing lyricism and clarity, Wingate shows how each type of cell possesses its own personality and history, illustrating a milestone of scientific discovery and exploring the stories of pioneering scientists like Ramon y Cajal and Francis Crick, and capturing their own fascinating shapes and patterns. Discover the ethereal world of the brain with this elegant little book - and find out how we all think and feel.
Gonadotropin-releasing hormone (GnRH) cells are the key regulators of reproductive function in all vertebrate organisms. The GnRH molecule is synthesized in a small number of neurons in rostral hypothalamic regions of the brain. In mammals, these neurons release the GnRH decapeptide into the portal capillary system leading to the anterior pituitary gland. There, GnRH causes the release of the gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn act upon the gonads to stimulate their maturation, and to cause synthesis of sex steroid hormones, estrogen, progesterone and testosterone. Although each of the levels of the hypothalamic-pituitary-gonadal axis is critical for reproductive function, GnRH neurons play the primary role in the control of reproductive maturation and adult reproductive function, and may even play a role in reproductive senescence. Since its discovery in 1970, there has been intense interest in GnRH-producing neurons, with more than 8000 papers and chapters in the last decade alone. Despite this activity of research in basic and clinical science, there has never been a book written specifically on GnRH neurons. GnRH: The Master Molecule of Reproduction aims to bring together the large and diverse literature of both laboratory and applied research that focuses on these unique cells. This book will provide basic background into reproductive neuroendocrinology, as well as specifics regarding the role of GnRH neurons in the control of reproduction. Students studying endocrinology, reproduction, neuroendocrinology or molecular endocrinology will benefit from this book. In addition, this book will take a multi-species approach which will be useful both to basic researchers as well as clinicians. Whenever possible, species differences and similarities will be presented, and if possible, studies on humans, or the clinical relevance of basic research findings to humans will be discussed (such as the treatment of reproductive disorders such as abnormalities in pubertal development, or infertility).
Neurotransmitter Methods is intended as a bench-side companion for researchers who seek to identify, locaHze, or measure neurotransmitters and/or to identify sites of neurotransmitter action. Each method is detailed in a user-friendly "recipe" format and the protocols are accompanied by extensive notes to high light and explain crucial steps. Approaches utilizing an incredibly diverse array of modem techniques are presented: methods including HPLC, histochemistry, immunocytochemistry, in situ hybridization, mass spectrometry, microdialysis, and electrochemistry all make at least one appearance. In addition, protocols for associated methodologies, including the production of brain slices, dissociated neurons, synaptosomes/synaptoneurosomes, and neuronal plasma membranes are presented. Methods applicable to most of the recognized chemical types of neu rotransmitter are to be found and, although you may find absent any mention of your favorite neurotransmitter, many of the protocols are sufficiently general to be adapted to alternative uses. So, how does this book contribute usefiilly to the horde of methods volumes stampeding across our bookshelves? 1 hope that the strength oiNeurotransmitter Methods lies in the variety of its content. The book provides in a single volume an array of techniques that could take a researcher from selection and preparation of a tissue source through to identification and measurement of neurotransmitter content and even onto characterization of neurotransmitter sites of action. Furthermore, the diversity of approaches presented reflects the need for today's bench neuroscientist to be a bit of a "jack (or a "jill" ) of all trades."
Brain Landscape: The Coexistence of Neuroscience and Architecture is the first book to serve as an intellectual bridge between architectural practice and neuroscience research. John P. Eberhard, founding President of the non-profit Academy of Neuroscience for Architecture, argues that increased funding, and the ability to think beyond the norm, will lead to a better understanding of how scientific research can change how we design, illuminate, and build spaces. Inversely, he posits that by better understanding the effects that buildings and places have on us, and our mental state, the better we may be able to understand how the human brain works. This book is devoted to describing architectural design criteria for schools, offices, laboratories, memorials, churches, and facilities for the aging, and then posing hypotheses about human experiences in such settings.
The Handbook of Neurolinguistics is a state-of-the-art reference
and resource book; it describes current research and theory in the
many subfields of neurolinguistics and its clinical application.
Thorough and clearly written, the Handbook provides an excellent
overview of the field of neurolinguistics and its
development.
Sensory substitution and augmentation devices are built to try to replace or enhance one sense by using another sense. For example, in tactile-vision, stimulation of the skin driven by input to a camera is used to replace the ordinary sense of vision that uses our eyes. The feelSpace belt aims to give people a magnetic sense of direction using vibrotactile stimulation driven by a digital compass. Fiona Macpherson brings together researchers -neuroscientists, psychologists and philosophers -who are developing these technologies, studying the minds and behaviour of subjects who use them. Sensory Substitution and Augmentation has three specific aims. The first is to present the latest empirical research on sensory substitution and augmentation. Second, philosophers and scientists who adopt a very different approach comment on the empirical work. Their commentaries are often critical of the assumptions of the work, but often they make and call for clarifications, suggest extensions to the work, or comment on features of the application of the work that the original authors do not. This is one reason why Sensory Substitution and Augmentation is more than simply a collection of papers on the same topic. Finally, philosophers look at the nature of sensory substitution and augmentation, tackling issues such as the nature and limitations of sensory substitution, the nature of the sensory experiences, theories of perception, and the potential for these devices to help those people with disabilities, in part due to future amendments of the devices that are suggested. Throughout, there is a particular focus on the nature of the perceptual experiences, the sensory interactions, and the changes that take place in the mind and brain over time that occur while using and training to use these technologies.
In this volume specific cognitive sub-functions are identified and indications of how basic vestibular input contributes to each are described. The broad range of these functions is consistent with the broad spread of vestibular projections throughout the cortex. Combining vestibular signals about the head's orientation relative to gravity with information about head position relative to the body provides sufficient information to map body position onto the ground surface and underlie the sense of spatial position. But vestibular signals are also fundamental to sensorimotor control and even to high-level bodily perception such as the sense of body ownership and the anchoring of perspective to the body. Clinical observations confirm the essential role of vestibular signals in maintaining a coherent self-representation and suggest some novel rehabilitation strategies. The chapters presented in this volume are previously published in a Special Issue of Multisensory Research, Volume 28, Issue 5-6 (2015). Contributors are: M. Barnett-Cowan, O. Blanke, J. Blouin, G. Bosco, G. Bottini, J.-P. Bresciani, J.C. Culham, C.L. Darlington, A.W. Ellis, E.R. Ferre, M. Gandola, L. Grabherr, S. Gravano, P. Grivaz, E. Guillaud, P. Haggard, L.R. Harris, A.E.N. Hoover, I. Indovina, K. Jauregu Renaud, M. Kaliuzhna, F. Lacquaniti, B. Lenggenhager, C. Lopez, G. Macauda, V. Maffei, F.W. Mast, B. La Scaleia, B.M. Seemungal, M. Simoneau, P.F. Smith, J.C. Snow, D. Vibert, M. Zago, and Y. Zheng.
Tinnitus and Hyperacusis: Facts, Theories, and Clinical Implications provides an overview on this burgeoning field, covering the underlying mechanisms and potential treatments for these disorders. The book begins with an overview of the etiology and genetics behind tinnitus and hyperacusis. The author then proposes two parallel neural pathways underlying these conditions and provides a basis for connecting animal to human research. Neurotransmitters, neuromodulators and immediate early genes are discussed, along with a detailed comparison of about a dozen models aimed at explaining tinnitus and hyperacusis, including the neurophysiological model, the neural synchrony model and the cortical map reorganization and filling-in model. Potential treatments of tinnitus and hyperacusis, from behavioral to non-invasive neuromodulation are also discussed. This book is written for clinical neuroscientists, audiologists, neuro-otologists, neurologists and clinical psychologists.
Birds and reptiles have long fascinated investigators studying hearing and the auditory system. The highly evolved auditory inner ear of birds and reptiles shares many characteristics with the ear of mammals. Thus, the two groups are essential in understanding the form and function of the vertebrate and mammalian auditory systems. Comparative Hearing: Birds and Reptiles covers the broad range of our knowledge of hearing and acoustic communication in both groups of vertebrates. This volume addresses the many similarities in their auditory systems, as well as the known significant differences about hearing in the two groups. |
