Tinnitus and Hyperacusis: Facts, Theories, and Clinical Implications provides a critical overview of the burgeoning field of research studying the underlying mechanisms and potential treatments for these two disorders. The book begins with an overview of the etiology and genetics behind tinnitus and hyperacusis. The author proposes two parallel neural pathways underlying these conditions and provides a basis for connecting animal research to human research. Neurotransmitters, neuromodulators and immediate early genes are discussed. The book also provides a detailed comparison of about a dozen models aiming at explaining tinnitus and hyperacusis, including the neurophysiological model, the neural synchrony model and the cortical map reorganization and filling-in model. Potential treatments of tinnitus and hyperacusis, from behavioral to non-invasive neuromodulation are discussed. This book is written for clinical neuroscientists, audiologists, neuro-otologists, neurologists and clinical psychologists.
