Project Details

The inner ear houses the delicate sensory hair cells and auditory neurons that transduce sound into an electrical signal, and relay this information to the brain.  This structure is highly vulnerable to conditions such as ischaemia, excessive noise exposure, and inflammation that can lead to acidification. In this project we explore the ion channels that are sensitive to changes in pH and their role in hearing loss. We use a range of experimental models together with electrophysiological tests, immunohistochemistry and imaging techniques.
