Abstract

Tinnitus is a symptom characterized by the perception of a sound without an exter- nal stimulus. Although the pathophysiology of tinnitus initially involves an alteration of the inner ear function, the perception of it and the degree of distress associated with it depends on changes in cognitive and emotional brain networks. In this article, we review the changes that exist at the cochlea, brainstem, thalamus and a widespread cerebral networks that account for tinnitus, discussing how this new conceptualization has significant clinical implications and allows a better understanding of the symptoms associated with tinnitus, its co-morbidities, and how this view has allowed the develop- ment of new therapies.
