Keypoints

  1. 1.

    Different methods have successfully been used for detecting tinnitus-related changes in the brain; chief among them are neuroimaging, electroencephalography and magnetoencephalography.

     
  2. 2.

    These methods make it possible to detect noninvasively neuronal activity in the human brain and determine the anatomical location of the activity.

     
  3. 3.

    Findings from neuroimaging have already contributed to a better understanding of the pathophysiological changes underlying the different forms of tinnitus

     
  4. 4.

    The different neuroimaging methods hold the potential to be further developed as methods for diagnosis, outcome assessment, and outcome prediction.

     
  5. 5.

    Replication of studies with larger sample sizes and clinically well-characterized individuals with tinnitus­ is needed.
