Fig. 4.

The ratio of hair cell height to width as a function of normalized distance from the neural papillar edge, for nine different positions along the papilla, as indicated (A–I). The dashed line at a ratio of 1 indicates the commonly used criterion for distinguishing tall and short hair cells (tall above and short below). J Percentage of tall (dark graybar) and short (light graybar) hair cells as a function of normalized distance from the apical end of the papilla. THC tall hair cell; SHC short hair cell.
