Cochlea (gray) of a Mongolian gerbil with optical cochlea implant. Its LEDs (green) are oriented towards the Rosenthal canal (dark blue), which houses the cell bodies of spral ganglion neurons, whose processes collectively form the auditory nerve. The illustration shows the nerve signals to stimulation with the LEDs. The different colors in the Rosenthal canal illustrate the spatial distribution and intensity of the generated nerve signal.

For an improved listening experience – optical cochlear implants generate more precise nerve signals than electrical models

-esearchers at the University Medical Center Göttingen (UMG) have demonstrated in an animal model that optical cochlear implants generate nerve signals that are more easily distinguishable than those produced by conventional electrical implants. Nerve signals transmit auditory information — such as sound waves, pitch, and volume — to the brain,

For better hearing restoration – optical cochlear implants generate more precise neural activation than electrical models

Researchers at the University Medical Center Göttingen (UMG) have demonstrated in an animal model that optical cochlear implants generate nerve signals that are more distinguishable than those produced by conventional electrical implants.
