Download or read book Noise Induced Hearing Loss written by Colleen G. Le Prell and published by Springer Science & Business Media. This book was released on 2011-10-30 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exposure to loud noise continues to be the largest cause of hearing loss in the adult population. The problem of NIHL impacts a number of disciplines. US standards for permissible noise exposure were originally published in 1968 and remain largely unchanged today. Indeed, permissible noise exposure for US personnel is significantly greater than that allowed in numerous other countries, including for example, Canada, China, Brazil, Mexico, and the European Union. However, there have been a number of discoveries and advances that have increased our understanding of the mechanisms of NIHL. These advances have the potential to impact how NIHL can be prevented and how our noise standards can be made more appropriate.
Download or read book Magnesium in the Central Nervous System written by Robert Vink and published by University of Adelaide Press. This book was released on 2011 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.
Download or read book Noise and the Brain written by Jos J. Eggermont and published by Academic Press. This book was released on 2013-09-12 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: In our industrialized world, we are surrounded by occupational, recreational, and environmental noise. Very loud noise damages the inner-ear receptors and results in hearing loss, subsequent problems with communication in the presence of background noise, and, potentially, social isolation. There is much less public knowledge about the noise exposure that produces only temporary hearing loss but that in the long term results in hearing problems due to the damage of high-threshold auditory nerve fibers. Early exposures of this kind, such as in neonatal intensive care units, manifest themselves at a later age, sometimes as hearing loss but more often as an auditory processing disorder. There is even less awareness about changes in the auditory brain caused by repetitive daily exposure to the same type of low-level occupational or musical sound. This low-level, but continuous, environmental noise exposure is well known to affect speech understanding, produce non-auditory problems ranging from annoyance and depression to hypertension, and to cause cognitive difficulties. Additionally, internal noise, such as tinnitus, has effects on the brain similar to low-level external noise.Noise and the Brain discusses and provides a synthesis of hte underlying brain mechanisms as well as potential ways to prvent or alleviate these aberrant brain changes caused by noise exposure. - Authored by one of the preeminent leaders in the field of hearing research - Emphasizes direct and indirect changes in brain function as a result of noise exposure - Provides a comprehensive and evidence-based approach - Addresses both developmental and adult plasticity - Includes coverage of epidemiology, etiology, and genetics of hearing problems; effects of non-damaging sound on both the developing and adult brain; non-auditory effects of noise; noise and the aging brain; and more

Download or read book Towards an Understanding of Tinnitus Heterogeneity written by Christopher Cederroth and published by Frontiers Media SA. This book was released on 2019-07-19 with total page 832 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tinnitus is the perception of a sound when no external sound is present. The severity of tinnitus varies but it can be debilitating for many patients. With more than 100 million people with chronic tinnitus worldwide, tinnitus is a disorder of high prevalence. The increased knowledge in the neuroscience of tinnitus has led to the emergence of promising treatment approaches, but no uniformly effective treatment for tinnitus has been identified. The large patient heterogeneity is considered to be the major obstacle for the development of effective treatment strategies against tinnitus. This eBook provides an inter- and multi-disciplinary collection of tinnitus research with the aim to better understand tinnitus heterogeneity and improve therapeutic outcomes.
Download or read book Plasticity and Signal Representation in the Auditory System written by Josef Syka and published by Springer Science & Business Media. This book was released on 2006-11-22 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The symposium that has provided the basis for this book, "Plasticity of the Central Auditory System and Processing of Complex Acoustic Signals" was held in Prague on July 7-10, 2003. This is the fourth in a series of seminal meetings summarizing the state of development of auditory system neuroscience that has been organized in that great world city. Books that have resulted from these meetings represent important benchmarks for auditory neuroscience over the past 25 years. A 1980 meeting, "Neuronal Mechanisms of Hearing" hosted the most distinguished hearing researchers focusing on underlying brain processes from this era. It resulted in a highly influential and widely subscribed and cited proceedings co-edited by professor Lindsay Aitkin. The subject of the 1987 meeting was the "Auditory Pathway - Structure and Function". It again resulted in another important update of hearing science research in a widely referenced book - edited by the late Bruce Masterton. While the original plan was to hold a meeting summarizing the state of auditory system neuroscience every 7 years, historical events connected with the disintegration of the Soviet Empire and return of freedom to Czechoslovakia resulted in an unavoidable delay of what was planned to be a 1994 meeting. It wasn't until 1996 that we were able to meet for the third time in Prague, at that time to review "Acoustical Signal Processing in the Central Auditory System".
Download or read book Aging neurogenesis and neuroinflammation in hearing loss and protection written by Marta Magariños and published by Frontiers Media SA. This book was released on 2015-09-29 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Worldwide, 278 million people are estimated to have moderate to profound hearing loss. Age-related hearing loss, also known as presbyacusis, affects approximately half of the population over 60 years old, making it the second most common cause of disability in older people. Hearing loss occurs when the sensory cells and neurons of the cochlea degenerate and die. The vestibular system, which holds the sense of balance, shares a common embryonic origin with the cochlea and together conform the inner ear. Balance problems are a trait of ageing to the point that balance ability is considered a sensor of physical decline and vestibular degeneration is the most common cause of falls in the elderly. Still the molecular bases of ageing in the vestibular system have not been studied in detail. Genetic and environmental factors contribute to the progression of age-related hearing loss (ARHL). Being noise the main environmental noxious agent for human hearing in the industrialized societies. There is no restorative treatment for deafness but functional replacement by means of prosthesis. Therefore, prevention and treatment of hearing loss is an unmet medical need. To develop innovative medical strategies against hearing loss, it is critical to understand the causes of ARHL and the essential pathways responsible for the manifestation of this complex disease. In this research topic, experts will discuss the stages and molecular elements of the damage and repair processes involved in ARHL, from cellular processes to molecules involved in aging. Oxidative stress takes a central stage as an essential element in the progression of injury and cell loss, and a target for cell protection strategies. Finally, the mechanisms of action and the potential of novel therapies for hair cell repair and protection will be discussed along with drug delivery strategies.

Download or read book New Advances in Electrocochleography for Clinical and Basic Investigation written by Jeffery T. Lichtenhan and published by Frontiers Media SA. This book was released on 2018-07-09 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrocochleography (ECochG) is an approach for objective measurements of physiologic responses from the inner ear. Measurements have classically been made from electrodes placed in the outer ear canal, on the tympanic membrane, the round window niche, or inside the cochlea. Recent innovations have led to ECochG being used for exciting new purposes that drive clinical practice and contribute to the basic understanding of inner ear physiology. Cochlear implant recording electrodes can monitor the preservation of residual, low-frequency acoustic hearing, both in the operating room and post-operatively. ECochG measurements can quantify differential effects of inner ear surgery or other manipulations on vestibular and auditory physiology simultaneously. Various attributes of cognitive neuroscience can be addressed with ECochG measurements from the auditory periphery. These advances in ECochG provide a way to understand a variety of inner ear diseases and are likely to be of value to many groups in their own clinical and basic research.
Download or read book Ringing ears the neuroscience of tinnitus written by Jos J. Eggermont and published by Frontiers E-books. This book was released on with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tinnitus (ringing in the ears) is a prevalent and often debilitating disorder with approximately 10% of people (incorporating ages from children to the elderly) perceiving it continuously, and in 1-3% of the population it seriously affects the quality of life. The most common cause of tinnitus is hearing loss, and its prevalence has surged as a result from the various large-scale military actions in the Middle East in the last decade. Recent advances have been made in the area of behavioral animal models, in the understanding of human brain imaging aspects of tinnitus, and in addressing the long-range changes in human brain connectivity. Furthermore continued exploration of the three major animal models of tinnitus: salicylate-induced, noise trauma induced, and resulting from somatic interactions with the auditory system has further delineated the relative roles of cochlear activity vs. central auditory system changes. Evidence for the role of neural synchrony changes in tinnitus originates both from human EEG and MEG studies as well as from neuron pair-correlation studies in animals.
