Cognitive neuroscience in tinnitus research: a current review.

Advances in methods of examining the human brain have led to a dramatic increase in specific knowledge about the origins of tinnitus. Neural modeling, behavioral measurements of hearing performance and psychological state, neuro-morphology, metabolic measurements of neural activity, electromagnetic recordings of synaptic potentials, and optical measurements of action potentials are all modalities that have provided insights or the promise of new information about the pathophysiology of tinnitus. This review examines these techniques and their contributions to knowledge about tinnitus.
