Optical cochlear implant in the cochlea of a gerbil

Optical cochlear implant in the cochlea of a gerbil: The Reconstruction of the spiral-shaped cochlea of a gerbil (grey) was generated by X-ray tomography images at the Institute for X-ray Physics (Prof. Dr. Tim Salditt) at the University of Göttingen. The spiral ganglion with the auditory nerve cells is shown in purple. The optical cochlear implant is shown in blue, the μLEDs are visible as blue dots.
