Moller's book in press at Springer, which typically have a strong clinical flavor, the present volume focuses on neural mechanisms of tinnitus and its behavioral consequences.

Chapter 2 overviews tinnitus prevalence and etiologies to set the tone for significance and complexity of this neurological disorder spectrum. Chapters 3-8 cover neuroscience of tinnitus in animal models from molecular mechanisms to cortical manifestation. Chapters 9-12 cover human brain responses to tinnitus
