New U of M Study Offers Promise in Developing Therapy for Tinnitus

Written by AudioNotch Team on January 07, 2014


Fascinating research from the University of Michigan has illuminated some amazing new results:
She explains that in tinnitus, some of the input to the brain from the ear’s cochlea is reduced, while signals from the somatosensory nerves of the face and neck, related to touch, are excessively amplified.

“It’s as if the signals are compensating for the lost auditory input, but they overcompensate and end up making everything noisy,” says Shore.

The new findings illuminate the relationship between tinnitus, hearing loss and sensory input and help explain why many tinnitus sufferers can change the volume and pitch of … Continue Reading

Cool Paper: “Homeostatic plasticity drives tinnitus perception in an animal model.”

Another cool paper has come out presenting animal research on the patho-physiology (abnormal physiology) that produces tinnitus. The abstract reads fairly easily:
Hearing loss often results in tinnitus and auditory cortical map changes, leading to the prevailing view that the phantom perception is associated with cortical reorganization.However, we show here that tinnitus is mediated by a cortical area lacking map reorganization.

High-frequency hearing loss results in two distinct cortical regions: a sensory-deprived region characterized by a decrease in inhibitory synaptic transmission and a normal hearing region showing increases in inhibitory and excitatory transmission and map reorganization.
The region deprived of … Continue Reading
