To hear again: Birds regrow damaged inner ear cells. Why can’t we?

Hunkered over her computer, Amanda Janesick, PhD, a postdoctoral scholar studying the biology of hearing, points to a series of microscopic images on the screen. The time-lapsed cross sections of a chicken’s inner ear show multitudes of hearing cells dying off and multitudes of new ones replacing them.

Cochlear Trafficking Mechanisms

This animation describes Dr. Peter Steyger and his laboratory’s research on how antibiotic molecules move from blood vessels into cochlear hair cells. His research is key to finding ways to prevent drug-induced deafness that can be caused by extended antibiotic treatment in premature infants and patients with systemic inflammation.

Antibiotic Trans-barrier Mechanisms in the Cochlea

This animation showcases research on how antibiotic molecules (red) can cross the endothelial cell barrier in the inner ear. The original illustration was drawn by Dr. Peter Steyger at Oregon Health & Science University and I modified it to create this animation. (Based on research published in Koo et al., Science Translational Medicine).

Aspirin-like pain reliever diflunisal blocks hearing protein: Rice University study: Commonly prescribed analgesic suppresses inner-ear protein

Aspirin-like pain reliever diflunisal blocks hearing protein: Rice University study: Commonly prescribed analgesic suppresses inner-ear protein

A new study has found that the aspirin-like drug diflunisal blocks the action of prestin, a key protein that is required for hearing.

Hearing Help

Hearing Help

For decades, the only remedies for hearing loss were devices such as hearing aids or cochlear implants. Now, the first pharmaceutical treatments may be on the way.

The goal: Bring music to cochlear implantees

Born profoundly deaf, Joseph Heng remembers sitting down at the piano in his family’s Singapore living room one day when he was 13 and pressing the keys. Heng, now a sophomore studying biomedical engineering in the Whiting School of Engineering, could discern the sounds of various notes because he had just been surgically fitted with a cochlear implant, a device designed to process and deliver sounds to the auditory nerve, allowing deaf people to hear.

How do estrogen and environmental stress affect the cochlea

How do estrogen and environmental stress affect the cochlea

The results from this project will help us to understand why women lose their hearing later in life than men, which could help to develop treatments.

Understanding Music Heard Through Cochlear Implants

Understanding Music Heard Through Cochlear Implants

Music sounds very different to cochlear implant users. Researchers are trying to improve the experience.
