NIH-funded research P01 program project

Understanding how aging affects hearing at the cellular level

Official title: Age-dependent plasticity of central auditory synapses

Funded at University of Arizona · NIH-10910246 · Data updated 2026-11-12

This study is looking at how getting older affects a part of your inner ear that helps you hear, to better understand why some people experience hearing loss as they age, and it could help find new ways to treat it in the future.

Who could benefit from this research

Could help

Ideal candidates for this research are elderly individuals experiencing early signs of hearing loss.

Less likely to help

Patients with hearing loss due to non-age-related factors, such as noise exposure or genetic conditions, may not benefit from this research.

What this research studies

This research investigates how age-related changes in the cochlea, a part of the inner ear, affect the central auditory system, which is responsible for processing sound. By examining specific types of auditory nerve synapses and their connections in the cochlear nucleus, the study aims to uncover the mechanisms behind age-related hearing loss. The researchers will use advanced techniques like electrophysiology and immunohistochemistry to analyze these changes. This work could lead to a better understanding of how hearing loss develops with age and potentially inform future treatments.

Why it matters

Potential benefit: If successful, this research could lead to improved strategies for preventing or treating age-related hearing loss.

How similar studies have gone: Previous research has shown promising results in understanding auditory processing changes with age, suggesting that this approach could yield valuable insights.
