Fig. 1.
Orientation of the optical fiber in the gerbil cochlea. This is a mid-modiolar cross-section of the gerbil cochlea. The arrow indicates the orientation and placement of the optical fiber with respect to the cochlea. The optical path length through the stimulated spiral ganglion cell population (circled) is approximately 250 μm. The calibration bar at the top left of the figure equals 500 μm.
