The video illustrates the concept of new optogenetic cochlear implants: sound from the piano is picked up by a microphone and transmitted to a processor which translates the sound into optical stimulation patterns via LEDs placed within the cochlea. This material relates to a paper that appeared in the 11 July, issue of Science Translational Medicine, published by AAAS. The paper, by C. Wrobel at University Medical Center Göttingen in Göttingen, Germany; and colleagues was titled, 'Optogenetic stimulation of cochlear neurons activates the auditory pathway and restores auditory-driven behavior in deaf adult gerbils.'
