Book Description
Leading researchers offer cutting-edge information on glutamate metabolism in the brain, examining the role of glutamate transporters and the involvement of glutamate receptors in the pathogenesis of acute neural trauma and neurodegenerative diseases. In addition, the authors discuss the treatment of these diseases with endogenous and exogenous antioxidants and glutamate receptor antagonists.

Book Description
Collectively, neurodegenerative diseases are characterized by chronic and progressive loss of neurons in discrete areas of the brain, producing debilitating symptoms such as dementia, loss of memory, loss of sensory or motor capability, decreased overall quality of life eventually leading to premature death. Two types of cell death are known to occur during neurodegeneration: (a) apoptosis and (b) necrosis. The necrosis is characterized by the passive cell swelling, intense mitochondrial damage with rapid loss of ATP, alterations in neural membrane permeability, high calcium influx, and disruption of ion homeostasis. This type of cell death leads to membrane lysis and release of intracellular components that induce inflammatory reactions. Necrotic cell death normally occurs at the core of injury site. In contrast, apoptosis is an active process in which caspases (a group of endoproteases with specificity for aspartate residues in protein) are stimulated. Apoptotic cell death is accompanied by cell shrinkage, dynamic membrane blebbing, chromatin condensation, DNA laddering, loss of phospholipids asymmetry, low ATP levels, and mild calcium overload. This type of cell death normally occurs in penumbral region at the ischemic injury site and in different regions in various neurodegenerative diseases.

Book Description
Traumatic brain injury (TBI) remains a significant source of death and permanent disability, contributing to nearly one-third of all injury related deaths in the United States and exacting a profound personal and economic toll. Despite the increased resources that have recently been brought to bear to improve our understanding of TBI, the developme

Book Description
Glutamate is the most pervasive neurotransmitter in the central nervous system (CNS). Despite this fact, no validated biological markers, or biomarkers, currently exist for measuring glutamate pathology in CNS disorders or injuries. Glutamate dysfunction has been associated with an extensive range of nervous system diseases and disorders. Problems with how the neurotransmitter glutamate functions in the brain have been linked to a wide variety of disorders, including schizophrenia, Alzheimer's, substance abuse, and traumatic brain injury. These conditions are widespread, affecting a large portion of the United States population, and remain difficult to treat. Efforts to understand, treat, and prevent glutamate-related disorders can be aided by the identification of valid biomarkers. The Institute of Medicine's Forum on Neuroscience and Nervous System Disorders held a workshop on June 21-22, 2010, to explore ways to accelerate the development, validation, and implementation of such biomarkers. Glutamate-Related Biomarkers in Drug Development for Disorders of the Nervous System: Workshop Summary investigates promising current and emerging technologies, and outlines strategies to procure resources and tools to advance drug development for associated nervous system disorders. Moreover, this report highlights presentations by expert panelists, and the open panel discussions that occurred during the workshop.

Book Description
The book is intended both for scientists already involved in the field, who may want a broader knowledge of all the aspects related to this complex mechanism, as well as for PhD or MD students, residents and neurologists wishing to learn more about a common mechanism involved in neuronal damage, driven by scientific curiosity or by the need to understand how new drugs, already on the market, may or may not work in various neurological disorders. With this aim, the book is basically divided into two parts, designed to be mutually integrated: - The first part covers all basic mechanisms of excitotoxicity, from glutamate metabolism, release, activity on various pre- and post-synaptic receptors, reuptake and their regulations, - The second part focuses on each neurologic disorder where this mechanism seems to play a major role, by examining in details pre-clinical and clinical evidences as well as treatment strategies in animal models and in patients. - To accomplish this complex task, world leaders in various fields, who did major contributions to define the problem and to open new avenues and are also actively working at present, agreed to put their expertise to launch the first complete and advanced level book on the role of excitotoxicity in neurologic diseases.

Book Description
The NMDA receptor plays a critical role in the development of the central nervous system and in adult neuroplasticity, learning, and memory. Therefore, it is not surprising that this receptor has been widely studied. However, despite the importance of rhythms for the sustenance of life, this aspect of NMDAR function remains poorly studied. Written

Book Description
What is schizophrenia? This is one of the most controversial questions in psychiatry and mental health research; however, in the last twenty years, there have been significant advances in our understanding of the topic. This book provides a balanced, comprehensive and up-to-date overview of the neuropathology of schizophrenia and its interpretation, covering the latest evidence derived from all fields of research, from brain scans to microscopy. The authors include many of the foremost international authorities in this rapidly developing field.
