Figure 14.

Procedures for virtually dissecting a three-dimensional basilar membrane (a; steps 1-4) then plotting the location of hair cells (steps 5 and 6). The top left image in b shows the upper two turns of the cochlea as looking down through the apex, the lower left image is after rotation away from apex. Boxed areas are shown to the right. Here note that from an apex down view, the orientation of outer hair cells obscure accurate identification of individual cells, while after rotation individual cells can be recognized. Dashed line marks the same location in both images. IHC, inner hair cells; OHC, outer hair cells.
