Book Description
A number of first and second order neurons of the guinea pig auditory system were studied extensively in an attempt to determine the method by which information is conveyed. Single neuron electrophysiological techniques with anatomical controls were used in the study and in response to several different stimuli, various response patterns were observed. Statistical methods of analysis, using a digital computer, were employed. Each fiber in the auditory nerve appears to convey only fragmentary information; therefore, the information carried by a number of fibers is required to extract all the information about a single signal. The data suggest that a pulse density modulation system of encoding is used, in which the 'carrier' appears to be the irregular spontaneous background activity, the pulse density of which is actively increased and decreased to convey information about both pitch and loudness. The system appears to be much more sensitive to sound changes than to absolute values. For example, pulse density correlated far better with rate-of-change of stimulus intensity than with absolute levels of intensity. In addition to frequency and amplitude, the interval between successive stimuli may be an important parameter of stimulation.

Book Description
Efficient auditory processing requires the rapid integration of transient sensory inputs. This is exemplified in human speech perception, in which long stretches of a complex acoustic signal are typically processed accurately and essentially in real-time. Spoken language thus presents listeners’ auditory systems with a considerable challenge even when acoustic input is clear. However, auditory processing ability is frequently compromised due to congenital or acquired hearing loss, or altered through background noise or assistive devices such as cochlear implants. How does loss of sensory fidelity impact neural processing, efficiency, and health? How does this ultimately influence behavior? This Research Topic explores the neural consequences of hearing loss, including basic processing carried out in the auditory periphery, computations in subcortical nuclei and primary auditory cortex, and higher-level cognitive processes such as those involved in human speech perception. By pulling together data from a variety of disciplines and perspectives, we gain a more complete picture of the acute and chronic consequences of hearing loss for neural functioning.

Book Description
Hearing: Anatomy, Physiology and Disorders of the Auditory System provides detailed information about the anatomy and physiology of the entire auditory system and it describes important aspects of disorders of the middle ear, the cochlea, and the nervous system in a comprehensive manner. Most other textbooks on Hearing are focused on either the periphery or the central nervous system and rarely integrate anatomy and physiology with clinical issues. In the past years, it has become apparent that pathologies of the peripheral parts of the auditory system affect the function of the nervous system, and vice versa. It is thus more and more important to view the peripheral and central parts of the auditory system in an integrative way. This book integrates descriptions of disorders of the ear and the nervous system and provides a comprehensive coverage of anatomy and physiology of the entire auditory system. The book introduces the role of neural plasticity in the symptoms of disorders such as tinnitus, hyperacusis and phonophobia. A separate chapter discusses cochlear and auditory brainstem implants. · This book provides a thorough understanding of the anatomy and function of the auditory system · Provides thorough information on the peripheral nervous system and auditory organs as well as the central nervous system· As valuable for students of and reasearchers in basic sciences (biology, psychology, neuroscience, audiology etc) as for clinicians· Offers an introduction into psychoacoustics and physical acoustics· Presents information on important disorders of the auditory system (including Tinnitus, · Includes chapter on cochlear and auditory brainstem implants· Fully illustrated with carefully selected images

Book Description
Hearing Science and Hearing Disorders focuses on the nature of the processes in the inner ear and the nervous system that mediate hearing. Organized into eight chapters, this book first discusses the nature of speech communication, the extent of hearing problems, and the pathophysiology of hearing. Four core chapters follow, in which four areas of central importance to understanding hearing disorders and their effects are covered. These areas are assessment of auditory function, the scope for technological solutions, the nature of audio-visual speech perception, and the effects of deafness upon speech production. This book will be valuable to students; to academic and professional workers concerned with hearing, speech, and their disorders; and to scientifically or medically literate people in general.
