Download or read book The Human Brainstem written by Hannsjörg Schröder and published by Springer Nature. This book was released on 2023-09-09 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human brainstem has long been a neglected area in clinical medicine. This is shown by the fact that there is no introductory book on the neuroanatomy and pathology of this region. This book is intended to introduce the reader to the neuroanatomy of the human brainstem and combines an atlas with detailed information on the individual structures. The atlas features a state-of-the-art magnetic resonance imaging series, histological specimens (Darrow Red and Campbell staining) and a plastinate-based topographical part, which allows direct comparison of histological and topographical findings with neuroimaging. In addition, the reader is guided along the brainstem neuromer model through the human brainstem and learns about the functional properties of the individual structures of the brainstem. Where appropriate, peripheral targets of brainstem structures are illustrated and explained. Furthermore, each chapter covers the most important neurological disorders affecting the brainstem. This book aims to demonstrate that sound anatomical knowledge is required to understand brainstem pathology. It will particularly help those new to the field to better understand the complex anatomy of the human brainstem and will be useful to basic and clinical neuroscientists alike.

Download or read book Discovering the Brain written by National Academy of Sciences and published by National Academies Press. This book was released on 1992-01-01 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."

Download or read book Human Brainstem Vessels written by Henri M. Duvernoy and published by Springer Science & Business Media. This book was released on 2013-11-22 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: I am greatly pleased and honoured to have been invited by Professor HENRI DUVERNOY to contribute a foreword to this book, especially since I became aware of the magnitude of his researches upon the cerebral vessels only a few years ago. These researches have, in fact, been pursued for almost two decades, beginning with a study of the hypophyseal vessels in 1958. More recently he has published a monograph entitled "The Superficial Veins of the Human Brain", and those who know this book will have noted the succinct clarity of the descriptive text and the superb quality ofthe photographs with which this chef-d'oeuvre is illustrated. This outstanding contribution to intimate detail of the superficial vascularization of the brainstem is now complemented by a second volume on internal angio-architec ture. As before, the emphasis is upon direct photographic evidence, and again the photographs are of a quality which must be almost unsurpassable. Those who are familiar with the technique of vascular injection of the brain and of the diffi culties of micro-anatomical identification, will applaud the excellence of Professor DUVERNOY' s preparations. Even the smallest named nuclei and fasciculi of nerve fibres are displayed most effectively. From study of these details, in conjunction with other descriptions of brain stern vessels (to which Professor DUVERNOY has hirnself contributed much), the vascular supply and drainage of all the recognised entities in the brain stern can be deduced.

Download or read book The Human Brain Stem and Cerebellum written by Henri M. Duvernoy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study of the brain stem and the cerebellum is the sequel to a previous study of the brain (cerebral hemispheres and diencephalon) [82]. The brain stem and cerebellum are dealt with here for the same purpose as was the brain in the previous work, i.e., to reach, step by step, knowledge that is comprehensive enough for an understanding of an atlas of sections and its clinical use. Following a brief survey of the methods used, the first chapter describes the brain stem and cerebellum surfaces as well as their location in the posterior cranial fossa. The second and the third chapter, respectively, describe the brain stem and cerebellum structures followed by brief surveys of their functions, enabling the reader to obtain an introductory view of the role of both the nuclei and fasciculi. The fourth chapter studies the brain stem vascular network in detail. Thus, this chapter sums up the results of research on brainstem superficial blood vessels and their intra nervous territories that were already presented in two previous works [79, 80]. By contrast, presentation of the cerebellar vascularization follows the previous literature.

Download or read book The Upper Brainstem in the Human written by B. Schlesinger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was when the author of this book was working in the Department of Human Anatomy at Oxford University that Prof. W.E. Le Gros Clark encouraged him to study the vascularization of the brain. Le Gros Clark, who has an international reputation for his research on the diencephalon, may thus be regarded as one of the initiators of this investigation. The prese!1t work is born of the happy coinicidence of a number of circumstances, namely, the author's possessing detailed anatomic knowledge and suitable techniques of carrying on research, and present the results, great patience, inventiveness and a special talent for dealing with highly complex material. It is necessary to know all this in order to understand how the author of this monograph was in the position to do such painstakingly detailed research on a subject of extreme complexity and to present it here in graphic and written form. The atlas fills a long felt want among neurosurgeons and researches in neuroana tomy as regards both the form and position of the nuclei and fiber tracts of the upper brain stem and the type and arrangement of its finer vascularization.

Download or read book The Cerebral Circulation written by Marilyn J. Cipolla and published by Biota Publishing. This book was released on 2016-07-28 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Brainstem Disorders written by Peter P. Urban and published by Springer Science & Business Media. This book was released on 2011-06-24 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The topography of the brainstem is complex, and even experienced neurologists find it challenging to localize brainstem lesions and diagnose brainstem disorders. This richly illustrated book provides a comprehensive review of brainstem disorders and presents the clinical knowledge necessary for diagnosis. The opening sections document the brainstem neuroanatomy and discuss current diagnostic methods. The entire spectrum of clinical findings in brainstem disorders is then described, and topodiagnostic aspects of the neurological findings are explained in detail. The descriptions of brain stem disorders are consistently structured and are supported by many MR images and short case reports. In addition to primary brainstem lesions, such as vascular brainstem syndromes, other disorders are considered that do not exclusively show brainstem symptoms or signs, e.g., multiple sclerosis. This book will serve as an invaluable reference work for neurologists in clinical practice or further education.

Download or read book Magnetic Resonance of Myelin Myelination and Myelin Disorders written by Jacob Valk and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 734 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic resonance imaging (MRI) is now considered the imaging modality of choice for the majority of disorders affecting the central nervous system. This is particularly true for gray and white matter disorders, thanks to the superb soft tis sue contrast in MRI which allows gray matter, unmyelinated, and myelinated white matter to be distinguished and their respective disorders identified. The pre sent book is devoted to the disorders of myelin and myelination. A growing amount of detailed in vivo information about myelin, myelination, and myelin dis orders has been derived both from MRI and from MR spectroscopy (MRS). This prompted us to review the clinical, laboratory, biochemical, and pathological data on this subject in order to integrate all available information and to provide im proved insights into normal and disordered myelin and myelination. We will show how the synthesis of all available information contributes to the interpretation of MR images. After a brief historical review about the increasing knowledge on myelin and my elin disorders, we propose a new classification of myelin disorders based on the subcellular localization of the enzymatic defects as far as the inborn errors of me tabolism are concerned. This classification serves as a guide throughout the book. All items of the classification will be discussed and, whenever relevant and possi ble, be illustrated by MR images.

Download or read book Cochlear and Brainstem Implants written by Aage R. Møller and published by Karger Medical and Scientific Publishers. This book was released on 2006-01-01 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today cochlear implants are the most successful of all prostheses of the nervous system. They are used in individuals who are deaf or suffer from a severe hearing deficiency caused by loss of cochlear hair cells. Auditory brainstem implants provide stimulation of the cochlear nucleus and are used in patients with an auditory nerve dysfunction, a deformed cochlea which does not allow cochlear implantation, or traumatic auditory nerve injury. In this volume different aspects of cochlear implantation such as the role of neural plasticity, the interaction with the development of the auditory system, and the optimal time of implantation in children (sensitive periods) are discussed in detail. Further, the processors and the algorithms used in modern cochlear implants are described The second part is devoted to auditory brainstem implants. It describes surgical techniques, methods for intraoperative testing as well as speech processing. It also deals with electrical stimulation of neural tissue and the neurophysiologic basis for cochlear and brainstem implants. The publication provides the latest scientific and clinical knowledge on cochlear and brainstem implants and is highly recommended to audiologists, otolaryngologists and also neurosurgeons.

Download or read book Brain Stem Localization and Function written by Louis R. Caplan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The localization of small vascular lesions within the brain-stem is the focal point of this volume which correlates clinical examination, evoked potentials, brain-stem reflexes and imaging techniques in one overview. For the first time, a group of experts has been brought together to summarize the various methods for detecting functional disturbances of specialized structures, to correlate these findings with morphologic criteria (MRI) and, finally, to elaborate patterns of abnormal findings which are characteristic of small brain-stem lesions. You are thus informed about neuro-physiological techniques which are superior to imaging techniques in local brain-stem pathology.

Download or read book Motor Function of the Pharynx Esophagus and Its Sphincters written by Ravinder Mittal and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deglutition or a swallow begins as a voluntary act in the oral cavity but proceeds autonomously in the pharynx and esophagus. Bilateral sequenced activation and inhibition of more than 25 pairs of muscles of mouth, pharynx, larynx, and esophagus is required during a swallow. A single swallow elicits peristalsis in the pharynx and esophagus along with relaxation of upper and lower esophageal sphincters. Multiple swallows, at closely spaced time intervals, demonstrate deglutitive inhibition; sphincters remain relaxed during the entire period, but only the last swallow elicits peristalsis. Laryngeal inlet closure or airway protection is very important during swallow. Upper part of the esophagus that includes upper esophageal sphincter is composed of skeletal muscles, middle esophagus is composed of a mixture of skeletal and smooth muscles, and lower esophagus, including lower esophageal sphincter, is composed of smooth muscles. Peristalsis progresses in seamless fashion, despite separate control mechanism, from the skeletal to smooth muscle esophagus. The esophagus's circular and longitudinal muscle layers contract synchronously during peristalsis. Sphincters maintain continuous tone; neuromuscular mechanisms for tonic closure in the upper and lower esophageal sphincters are different. Lower esophageal sphincter transient relaxation, belching mechanism, regurgitation, vomiting, and reflux are mediated via the brain stem.

Download or read book Investigating the human brainstem with structural and functional MRI written by Florian Beissner and published by Frontiers E-books. This book was released on 2014-07-30 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brainstem is one of the least understood parts of the human brain despite its prime importance for the maintenance of basic vital functions. Owing to its role as a relay station between spinal cord, cerebellum and neocortex, the brainstem contains vital nodes of all functional systems in the central nervous system, including the visual, auditory, gustatory, vestibular, somatic and visceral senses, and the somatomotor as well as autonomic nervous systems. While the brainstem has been extensively studied in animals using invasive methods, human studies remain scarce. Magnetic resonance imaging (MRI) as a non-invasive and widely available method is one possibility to access the brainstem in humans and measure its structure as well as function. The close vicinity of the brainstem to large arteries and ventricles and the small size of the anatomical structures, however, place high demands on imaging as well as data analysis methods. Nevertheless, the field of brainstem-(f)MRI has significantly advanced in the past few years, largely due to the development of several new tools that facilitate studying this critical part of the human brain. Within this scope, the goal of this Research Topic is to compile work representing the state of the art in functional and structural MRI of the human brainstem.
