Figure 4: (a) Representative photomigrographs showing radial section of the organ of Corti (OC) from basal turn. Compared to noise and RX90 groups, RX180 group exhibits relatively preserved outer hair cells (OHCs). Note the decreased height (from reticular lamina to basilar membrane) of the OC due to pillar buckling (arrowheads) in the noise group. (b) Grading scores for the degeneration of OC are compared across groups. I = Inner hair cell; O1, O2, O3 = Three OHC rows; IT = Inner tunnel of Corti
