Functional Manifestations of Pressure Changes in the Middle Ear System

Completed · Not applicable

Conditions studied: Middle-ear Function

In brief

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.
