Neuromodulatory Function In Auditory Processing

Neuromodulatory Function in Auditory Processing

The Oxford Handbook of the Auditory Brainstem

The Oxford Handbook of The Auditory Brainstem provides an introduction as well as an in-depth reference to the organization and function of ascending and descending auditory pathways in the mammalian brainstem. Individual chapters are organized along the auditory pathway beginning with the cochlea and ending with the auditory midbrain. Each chapter provides an introduction to the respective area, and summarizes our current knowledge before discussing disputes and challenges the field currently faces. A major emphasis throughout this book is on the numerous forms of plasticity that are increasingly observed in many areas of the auditory brainstem. Several chapters focus on neuronal modulation of function and synaptic, neuronal, and circuit plasticity, especially under circumstances when they occur most prominently: during development, aging, and following peripheral hearing loss. In addition, the book addresses the role of trauma-induced maladaptive plasticity with respect to its contribution in generating central hearing dysfunction such as hyperacusis and tinnitus. The book is intended for students and postdocs starting in the auditory field, and researchers of related fields who wish to get an authoritative and up-to-date summary of the current state of auditory brainstem research. For clinical practitioners in audiology, otolaryngology, and neurology, the book is a valuable resource of information about the neuronal mechanisms that are major candidates for the generation of central hearing dysfunction.

The Mammalian Auditory Pathways

The auditory system is a complex neural system composed of many types of neurons connected into networks. One feature that sets the auditory system apart from other sensory systems, such as somatosensory or visual systems, is the many stages of neural processing that occur between the ear in the periphery and the cerebral cortex. Each stage is composed of specialized types of neurons connected in specific microcircuits that perform computations on the information about sound. To understand this processing, all the tools of neuroscience must be employed. The proposed text integrates cell biology, synaptic physiology, and electrophysiology to fully develop the topic, presenting an overview of the functional anatomy of the central auditory system. It is organized based on the neuronal connectivity of the central auditory system, which emphasizes the neurons, their synaptic organization, and their formation of functional pathways and microcircuits. The goal of the book is to stimulate research into the cell biology of the central auditory system and the characteristics of the specific neurons and connections that are necessary for normal hearing. Future research on the development of the central auditory including that employing stem cells will require such information in order to engineer appropriate therapeutic approaches. ​
