Study Summary
This study is looking at whether functional magnetic resonance imaging (fMRI) can see if and when the brain responds to pressure stimulations of the eardrum. The study requires 2 visits, 1 for screening to determine eligibility and 1 for the fMRI. This study will help to understand how the middle ear system is controlled, which may have an impact on how people with middle ear disease are treated.
Primary Outcome
Subjects will have fMRIs while pressure is varied in the right ear (+/-40 decapascals). Changes in brain activation during pressure changes will be measured by fMRI during approximately 1 hour scanning time.
