Hearing disorders of many types begin in the inner ear, but they have long-term effects in the brain. The Hearing Research Group at NEOMED is a diverse group of scientists interested in how the central nervous system functions in association with hearing and vocal communication, how it is affected by hearing disorders, and how interventions of the peripheral and central nervous systems may ameliorate hearing disorders.
NEOMED researchers study several hearing and communication health issues:
- Age-related hearing loss
- Noise-induced hearing loss
- Hearing loss during development
- Auditory processing disorder
- Emotional disorders in speech communication
Of American adults (37.5 million) report some trouble with hearing.
1 in 12
Nearly 1 in 12 U.S. children ages 3-17 has had a disorder related to voice, speech, language or swallowing in the past 12 months.
Over 50 million Americans experience some form of tinnitus (ringing in the ears).
Potential molecular targets for noise-induced hearing loss in spiral ganglion neurons
We discovered circuits (red fibers contacting the blue and green nerve cell) that may allow us to tune in to sounds that are interesting and tune out sounds that are distracting. Dysfunction in these circuits may relate to the difficulties in hearing that often accompany aging.
