Tinnitus Neuroimaging

noninvasive neuromodulation of tinnitus with transcranial current stimulation techniques with insight into neurobiology and neuroimaging

background and aim: tinnitus is an auditory phantom percept in the absence of any objective physical sound source. although advances have been made in its treatment, there is very low percent of patients that report an elimination of their tinnitus. a novel approach using noninv­asive neuromodulation has emerged as an inter­esting and promising modality for tinnitus relief. our aim in this revi...

Tinnitus Neural Mechanisms and Structural Changes in the Brain: The Contribution of Neuroimaging Research

Introduction Tinnitus is an abnormal perception of sound in the absence of an external stimulus. Chronic tinnitus usually has a high impact in many aspects of patients' lives, such as emotional stress, sleep disturbance, concentration difficulties, and so on. These strong reactions are usually attributed to central nervous system involvement. Neuroimaging has revealed the implication of brain s...

Neuroimaging and Neuromodulation: Complementary Approaches for Identifying the Neuronal Correlates of Tinnitus

An inherent limitation of functional imaging studies is their correlational approach. More information about critical contributions of specific brain regions can be gained by focal transient perturbation of neural activity in specific regions with non-invasive focal brain stimulation methods. Functional imaging studies have revealed that tinnitus is related to alterations in neuronal activity o...

P28: Neuroimaging in Anxiety Disorders

In recent years, the development of neuroimaging techniques such as high-resolution magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), positron emission tomography (PET), or single photon emission tomography (SPECT) has promoted the identification of structural and functional characteristics underlying mental disorders to a great extent. In anxiety disorders, recent...
