It has been shown that a new light-based cochlear implant restores the auditory responses of one type of rodent, which could serve as a basis for a new generation Transmitting implants sound more precisely than traditional devices.
The study provides a proof of concept (which serves to verify that a theory can be usefully exploited) that the combination of optical stimulation and genetic manipulation can restore the perception of sound.
By Christian Wroberl of the German University of Göttingen, he used optogenetics, a method that combines optical and genetic methods, to carry out his experiment published by Science Translational Medicine.
Worldwide, about 360 million people have hearing loss and traditional cochlear implants can recover the hearing ability of many of them, stimulating ear cells with electrical signals.
