In the clinic at Giessen during the last few years there has been an extensive programme of research into the various aspects of lesions of the diencephalon and brain stem and the associated autonomic and metabolic disturbances. As a continuation of this research programme Ernst Grote has investigated the central neuronal and hormonal factors acting on the peripheral regulation of glucose metabolism and their diverse inter-relationships. This research was made possible not only by the availability of well-documented clinical and experi mental material with primary and secondary lesions of the hypo thalamus and brain stem, but also by the advances in clinical endo crinology and the development of radio-immuno-assays. By continuous systematic investigation of the basic values and their reaction to stress-tests, as well as to trauma and operation, he has elucidated the basic facts of the central and peripheral mechanisms which are concerned in the regulation of glucose, and also their disturbances. Of particular significance are his descriptions and interpretations of the characteristic hypothalamic syndromes, as combinations of hyperglycaemia, hyperinsulinaemia and hyperglucagonaemia; dif ferent syndromes are produced by lesions at various levels of the brain stem and in central brain death. From this starting point it was possible to develop a rational treatment of this hormonal dys regulation by means of somatostatin.

Most tissues and organs, such as the brain, need glucose constantly, as an important source of energy. The low blood concentrations of glucose (hypoglycemia) can cause seizures, loss of consciousness, and death. On the other hand, long lasting elevation of blood glucose concentrations (hyperglycemia) can result in blindness, renal failure, cardiac and peripheral vascular disease, and neuropathy. Therefore, blood glucose concentrations need to be maintained within narrow limits. The process of maintaining blood glucose at a steady-state level is called glucose homeostasis. This is accomplished by the finely hormone regulation of peripheral glucose uptake (glucose utilization), hepatic glucose production and glucose uptake during carbohydrates ingestion.

This book has a dual purpose, to review in depth the control of fuel homeostasis in the brain and the role of the nervous system in the control of fuel deposition in the body. From the methodological point of view the emphasis is on the application of advanced technologies to assess fuel transport and brain metabolism, the role of peptides in the neuroendocrine system and the response of the brain to hypoglycemia. These technologies include positron emmission tomography, nuclear magnetic resonance, immunocytochemistry, molecular biology, autoradiography. To study fuel homeostasis in the body advanced tracer methods that include modelling are set out. From the pathophysiological point of view the emphasis is on abnormalities in stress, brain metabolism in diabetes, eating and degenerative disorders. This book contains contributions from endocrinologists, physiologists, neurologists, psychoneuroendocrinOlogists, biophysicists, biochemists and experts in nutrition. This authorship represents a unique diversity of researchers who, for the first time, cover comprehensively the interaction between the nervous system and fuel homeostasis, both in health and disease. We hope this book will be an important source of information for both researchers and practicing clinicians. Mladen Vranic Suad Efendic Charles Hollenberg v ACKNOWLEDGEMENTS The Symposium from which this volume arose (University of Toronto, June 27-28, 1990) was the first Toronto-Stockholm symposium on Perspectives in Diabetes Research.

This book systemically describes the mechanisms underlying the neural regulation of metabolism. Metabolic diseases, including obesity and its associated conditions, currently affect more than 500 million people worldwide. Recent research has shown that the neural regulation of metabolism is a central mechanism that controls metabolic status physiologically and pathophysiologically. The book first introduces the latest studies on the neural and cellular mechanisms of hypothalamic neurons, hypothalamic glial cells, neural circuitries, cellular signaling pathways, and synaptic plasticity in the control of appetite, body weight, feeding-related behaviors and metabolic disorders. It then summarizes the humoral mechanisms by which critical adipocyte-derived hormones and lipoprotein lipase regulate lipid and glucose metabolism, and examines the role of the hypothalamus-sympathetic nerve, a critical nerve pathway from CNS to peripheral nervous system (PNS), in the regulation of metabolism in multiple tissues/organs. Furthermore, the book discusses the functions of adipose tissue in energy metabolism. Lastly, it explores dietary interventions to treat neural diseases and some of the emerging technologies used to study the neural regulation of metabolism. Presenting cutting-edge developments in the neural regulation of metabolism, the book is a valuable reference resource for graduate students and researchers in the field of neuroscience and metabolism.

This excellent book describes the roles of the suprachiasmatic nucleus (SCN) of the hypothalamus as a regulatory center of homeostatic mechanism and a circadian oscillator in mammals, including humans. The authors emphasize two important points based on their findings: 1) SCN plays a critical role in central regulation of energy metabolism through which a constant supply of glucose to the central nervous system (CNS) is well maintained; and 2) neurons responsible for the regulation of energy metabolism are located in the ventrolateral part of the SCN and receive retinal neural inputs through both the retinohypothalamic tract and the geniculohypothalamic tract. The authors then discuss the evolutionary importance of these points to the survival of mammals on earth. Other topics examined include the involvement of light in the regulation of neural activity of the autonomic nervous system through the retina and SCN, in addition to the relation of the SCN with regulations of other autonomic nerve functions, such as blood pressure and body temperature. Central Regulation of Energy Metabolism with Special Reference to Circadian Rhythm is important reading for researchers and students in neuroendocrinologists, neurobiologists, biochemists, endocrinologists, physiologists, chronobiologists, psychologists, pharmacologists, and others interested in the topic.

Gluconeogenesis, the metabolic process through which glucose or glycogen is synthesized from noncarbohydrate substrates, is critical for maintaining the plasma glucose level within a narrow range either in the fed or fasting (nutritional deprivation) state. Dysregulation of this pathway usually causes severe or even fatal outcomes. This book discusses a series of up-to-date topics about this critical process, including the fundamental biochemical reactions of glucose metabolism, the glucogenesis process in eukaryotic cells using the Dictyostelium discoideum as a model, the role of "gut-brain-liver axis" in the control of glucose homeostasis, and the new mathematic model for the monitoring and prediction of blood glucose. This book is written by international scientists with expertise in the study of gluconeogenesis. By presenting a clear and succinct review of the fundamentals of gluconeogenesis, it is expected to draw more attentions and stimulate more scientists to dedicate their researches in revealing the mechanism and its application of gluconeogenesis.
