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.

Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Book Description
Magnetic Resonance Spectroscopy: Tools for Neuroscience Research and Emerging Clinical Applications is the first comprehensive book for non-physicists that addresses the emerging and exciting technique of magnetic resonance spectroscopy. Divided into three sections, this book provides coverage of the key areas of concern for researchers. The first, on how MRS is acquired, provides a comprehensive overview of the techniques, analysis, and pitfalls encountered in MRS; the second, on what can be seen by MRS, provides essential background physiology and biochemistry on the major metabolites studied; the final sections, on why MRS is used, constitutes a detailed guide to the major clinical and scientific uses of MRS, the current state of teh art, and recent innovations. Magnetic Resonance Spectroscopy will become the essential guide for people new to the technique and give those more familiar with MRS a new perspective. - Chapters written by world-leading experts in the field - Fully illustrated - Covers both proton and non-proton MRS - Includes the background to novel MRS imaging approaches

Book Description
Until recently, monitoring of cerebral blood flow and metabolism was an unattained goal. Determination of cerebral blood flow was limited to intermittent measurements and particularly difficult to perform in critically ill patients. Meanwhile there are techniques available, however, to monitor cerebral blood flow and cerebral oxygenation, both globally and regionally. Therefore we thought it worthwhile to discuss these new continuous techniques and to compare them with well-known techniques which discontinuously measure CBF. For that purpose, an international workshop with some leading experts in the field was held in October 1992 in Berlin. The workshop consisted of about 20 lectures, either reviews on a special topic, or latest results. These contributions were given by invitation and were extensively discussed. Unfortunately it is impossible to reproduce the discussions. On the other hand, all speakers delivered a manuscript promptly after the meeting so that we were able to edit them within a short time. Since monitoring of cerebral blood flow in intensive care is a rapidly growing and changing topic, the written contributions should be quickly available. Authors, editors and publishers have tried to come close to this ideal. As editors we would like to thank the authors and the publishers who enabled us to come out with this volume of the proceedings as early as possible.

Book Description
The story of one man's evolution from naive and ambitious young intern to world-class neurosurgeon. With poignant insight and humor, Frank Vertosick Jr., MD, describes some of the greatest challenges of his career, including a six-week-old infant with a tumor in her brain, a young man struck down in his prime by paraplegia, and a minister with a .22-caliber bullet lodged in his skull. Told through intimate portraits of Vertosick’s patients and unsparing yet fascinatingly detailed descriptions of surgical procedures, When the Air Hits Your Brain—the culmination of decades spent struggling to learn an unforgiving craft—illuminates both the mysteries of the mind and the realities of the operating room.

Book Description
Cutting-edge research on hyperbaric oxygen therapy (HBOT) as a gene therapy to treat traumatic brain injuries, degenerative neurological diseases, and other disorders Hyperbaric oxygen therapy (HBOT) is based on a simple idea—that oxygen can be used therapeutically for a wide range of conditions where tissues have been damaged by oxygen deprivation. Inspiring and informative, The Oxygen Revolution, Third Edition is the comprehensive, definitive guide to the miracle of hyperbaric oxygen therapy. HBOT directly affects the body at the genetic level, affecting over 8,000 individual genes—those responsible for healing, growth, and anti-inflammation. Dr. Paul G. Harch’s research and clinical practice has shown that this noninvasive and painless treatment can help those suffering from brain injury or such diseases as: • Stroke • Autism and other learning disabilities • Cerebral palsy and other birth injuries • Alzheimer’s, Parkinson’s, multiple sclerosis, and other degenerative neurological diseases • Emergency situations requiring resuscitation, such as cardiac arrest, carbon monoxide poisoning, or near drowning For those affected by these seemingly “hopeless” diseases, there is finally hope in a proven solution: HBOT.
