Book Description
The brain is an extremely energy consuming part of the body, which makes it dangerously vulnerable to metabolic stress. It’s no wonder then that abnormalities of brain energy metabolism are becoming the usual suspects and a hallmark of many neurodegenerative diseases. The socioeconomic burden of these alone begs for urgent measures to be taken for better understanding both fundamental and applied problems of neuroenergetics and neuroprotection. For instance, brain imaging reveals that the diseased brains of Alzheimer’s patients cannot efficiently utilize the vital brain fuel, glucose. The resulting energy deficit causes neuronal hyperactivity, seizures and cognitive impairments. Administration of native energy substrates complementary to glucose is a logical (and attractive in its simplicity) approach in fighting the energy crisis in the brain*. The two closely related aspects of brain activity -- neuronal and metabolic – are currently considered to be of utmost importance in both fundamental and applied neuroscience. Although recently the studies of both brain activity and metabolism in normal conditions, under metabolic stress, and in neurodegenerative diseases have experienced significant progress, their overlapping areas deserve further clarification by joint efforts from experts in such fields as (1) energy demands, supplies, and efficiency at the cellular level: in neurons, glial elements, micro-vessels and in the process of their coordinated interactions; (2) specific roles of energy substrates in fine-tuning of the demand-supply mechanism in the condition of metabolic stress; and (3) the macro-level of energy homeostasis and dietary manipulations possible beneficial for neurodegenerative diseases. The result of combining into a coherent whole the recent findings in these fields will hopefully bring forward a broader view and better understanding of the knowledge continuum, which is under the threat of further fragmentation due to the unavoidable process of specialization in neuroscience. Current issue covers the three major groups of topics: 1. The Pros and Cons of studies of neuronal activity using brain slice preparations 2. The role of particular energy substrates in metabolic support of neuronal activity 3. The macro-level of energy homeostasis and the dietary manipulations that seem promising in prevention and correction of the diseases of brain energy metabolism.

Book Description
Brain Energy Metabolism addresses its challenging subject by presenting diverse technologies allowing for the investigation of brain energy metabolism on different levels of complexity. Model systems are discussed, starting from the reductionist approach like primary cell cultures which allow assessing of the properties and functions of a single brain cell type with many different types of analysis, however, at the expense of neglecting the interaction between cell types in the brain. On the other end, analysis in animals and humans in vivo is discussed, maintaining the full complexity of the tissue and the organism but making high demands on the methods of analysis. Written for the popular Neuromethods series, chapters include the kind of detailed description and key implementation advice that aims to support reproducible results in the lab. Meticulous and authoritative, Brain Energy Metabolism provides an ideal guide for researchers interested in brain energy metabolism with the hope of stimulating more research in this exciting and very important field.

Book Description
From the preface: “Neural Metabolism In Vivo aims to provide a comprehensive overview of neurobiology by presenting the basic principles of up-to-date and cutting-edge technology, as well as their application in assessing the functional, morphological and metabolic aspects of the brain. Investigation of neural activity of the living brain via neurovascular coupling using multimodal imaging techniques extended our understanding of fundamental neurophysiological mechanisms, regulation of cerebral blood flow in connection to neural activity and the interplay between neurons, astrocytes and blood vessels. Constant delivery of glucose and oxygen for energy metabolism is vital for brain function, and the physiological basis of neural activity can be assessed through measurements of cerebral blood flow and consumption of glucose and oxygen.... This book presents the complex physiological and neurochemical processes of neural metabolism and function in response to various physiological conditions and pharmacological stimulations. Neurochemical detection technologies and quantitative aspects of monitoring cerebral energy substrates and other metabolites in the living brain are described under the “Cerebral metabolism of antioxidants, osmolytes and others in vivo” section. Altogether, the advent of new in vivo tools has transformed neuroscience and neurobiology research, and demands interdisciplinary approaches as each technology could only approximate a very small fraction of the true complexity of the underlying biological processes. However, translational values of the emerging in vivo methods to the application of preclinical to clinical studies cannot be emphasized enough. Thus, it is our hope that advances in our understanding of biochemical, molecular, functional and physiological processes of the brain could eventually help people with neurological problems, which are still dominated by the unknowns.” -- In-Young Choi and Rolf Gruetter

Book Description
The second volume of the Handbook does not parallel any volume of the first edition; it is one more sign, or reflection, of the expansion of the field. By emphasizing the experimental approach, it illustrates the tools that have re cently become available for investigating the nervous system. Also, perhaps even more than other volumes, it illustrates the multidisciplinary nature of the field, requiring multidisciplinary methodology. It is now recognized that the availability of methodology is often the rate-limiting determinant of studies and that improvements or innovations in instrumentation can open up new avenues. A new improved method, although opening up new possibilities and being crucial to making advances, is only a tool whose use will determine its use fulness. If we do not recognize its possibilities, its use will be limited; if we do not recognize its limitations, it will mislead us. It is the possibilities and limitations and the results obtained that are illustrated here.

Book Description
This book is based on an international symposium titled "Cytochrome oxidase in energy metabolism and Alzheimer's disease," held as a satellite to the 27th meeting of the Society for Neuroscience, New Orleans, 1997. The symposium was dedicated in honor of Dr. Margaret T. T. Wong-Riley because, in our opinion, the cytochrome oxidase histo chemical method introduced by Dr. Wong-Riley in 1979 was the most significant break through to map energy metabolism in the entire brain since the 2-deoxyglucose method introduced by Dr. Louis Sokoloff and colleagues in 1977. Both of these metabolic map ping techniques have made monumental contributions to brain research by allowing an integral view of brain activity. They have also developed into various specialized tech niques, including applications to the human brain. One of these new applications, which is described in detail in this book, is the quantitative cytochrome oxidase cytochemical method used to study Alzheimer's disease. The objective of this book is to describe the role of cytochrome oxidase in neuronal metabolism and Alzheimer's disease. Whether genetic or environmental, the pathogenesis of Alzheimer's disease involves a cascade of multiple intracellular events, eventually re sulting in failure of oxidative energy metabolism. Could impairment of cytochrome oxi dase in energy metabolism initiate the degenerative process? Cytochrome oxidase function and dysfunction are discussed in relationship to neuronal energy metabolism, neurodegen eration, and Alzheimer's disease. The book is made up of 10 chapters, divided into three major parts.
