Neural Metabolism In Vivo


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

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.




Biochemical Factors Concerned in the Functional Activity of the Nervous System


Book Description

Biochemical Factors Concerned in the Functional Activity of the Nervous System presents the biological aspects concerned in the functional activity of the nervous system. This book covers several interesting topics concerning the central nervous system, including phospholipids, RNA synthesis, nerve impulse flow, and nerve growth factor. Comprised of 213 chapters, this book begins with an overview of the electron micrographs of calcium–ATP–phospholipid complexes. This text then examines the biochemical and histochemical studies on sectioned rat spinal cords, which demonstrated two types of monoamine-reducing drugs. Other chapters consider the diversity of antagonistic relations between the thiamine derivatives and vitamin B6, which is manifested by changes in the glutamate–GABA, histidine–histamine, tryptophan–serotonin, and tyrosine–noradrenaline systems. This book discusses as well the influence of a conditioned avoidance training experience on the incorporation of radioactive uridine into the RNA of mouse brain. The final chapter deals with the amino acid-incorporating activity of cerebral polyribosomes. This book is a valuable resource for biochemists, neurologists, pharmacologists, and biophysicists.




The Cerebral Circulation


Book Description

This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.




Neuron Signaling in Metabolic Regulation


Book Description

This book focuses on neuron signaling in the regulation of metabolism and body weight, and especially on methods used in these studies. Obesity and related metabolic syndromes have reached epidemic status, but still are no effective strategies for prevention and treatment. Body weight homeostasis is maintained by balanced food intake and energy expenditure, both of which are under the control of brain neurons. In the recent years, significant progress has been made in identifying specific neurons, neural pathways, and non-neuron cells in feeding regulation, as well as in delineating autonomic nervous systems targeting peripheral metabolic tissues in the regulation of energy expenditure and metabolism. This book reviews recent progress on important neuron signaling for body weight and metabolic regulation and the state-of-the-art methods that has been applied in this field, ranging from animal models with neuron-specific manipulations, pharmacology, optogenetics, in vivo Ca2+ imaging, and viral tracing. Readers will be exposed to latest research frontiers on neuron regulation of metabolism. Key Features Explores the role signaling between neurons plays with respect to metabolism Documents how neurotransmitters affect the regulation of feeding Describes various methods and technologies used to study the neuronal control of metabolism Includes contributions from an international team of leading researchers.
