- Reverse nerve signals from the brain to the ear may play a key role in causing tinnitus.
- When hearing is damaged, the brain boosts these signals to “amplify” sound, which can lead to ringing or hissing in the ears.
- Using advanced imaging, researchers watched this feedback system in action inside the cochlea of live mice.
- By blocking these backward signals, they believe tinnitus and related conditions like hyperacusis could be reduced.
- The treatment is still in early animal testing, and future drug development will aim to carefully balance signal reduction without harming hearing.
