All Three Rows of Outer Hair Cells Are Required for Cochlear Amplification

Figure 14

Block diagram of the OC. Force caused by sound stimulus is applied to the OC (i), and is then calculated (ii), leading to (iii). The forces generated by OHCs are determined by based on the force-displacement map, shown in Figure 6 (iv). OHC forces are applied to the OC in combination with (v), thus being known as a positive feedback system.
