Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main fMRI study parameter is the number of active voxels in the auditory cortex and the inferior colliculus. The amount of active voxels is a measure for the amount of activation caused by the application of the stimuli. The number of voxels is determined by comparing both tinnitus matching and non-matching stimuli to the silence. | — |
Secondary
| Measure | Time frame |
|---|---|
| A secondary fMRI study parameter is the number of active voxels in other areas of the brain. The AC and IC are the most important, but not the only neural correlates of tinnitus. Activity found in other regions of the brain is also taken into account for further analysis. | — |
