FIGURE 13.

Peak-to-peak radial (solid symbols) and longitudinal (open symbols) displacements as a function of depth relative to the RL, for four radial locations. All responses are from the apical turn region (CF ∼0.4 kHz) from the same animal (exp. 325). The stimulus frequency was 30 Hz. For this experiment, γ_R = 73° and γ_L = 95°. Zero-degrees phase indicates motion toward the spiral ligament in the radial direction and toward the base in the longitudinal direction. (A and E) Magnitude and phase of OPC region displacements, with RL defined as the top of the OPC. (B and F) Magnitude and phase of OHC1 region displacements, with RL defined as the top of the OHC1 hair bundles. (C and G) Magnitude and phase of OHC3 region displacement, with RL defined as the top of the OHC3 hair bundles. (D and H) Magnitude and phase of HC region displacement, with RL defined as the top of OHC3 hair bundles.
