Functional Neuroimaging

Keypoints

  1. 1.

    Different functional imaging methods, such as SPECT, PET, and fMRI, have been used for investigating tinnitus.

     
  2. 2.

    Neuroimaging methods have provided windows to the brain that allow detection of the localization of tinnitus-related changes in the brain.

     
  3. 3.

    Such studies have shown signs of abnormalities in many parts of the brain, including auditory brain regions but also nonauditory brain areas involved in sensory integration, in attention, or in emotional evaluation.

     
  4. 4.

    New treatment strategies have evolved from fMRI and PET findings of abnormal neuronal activity in the auditory cortex.
