Figure 7

Testing for scaling symmetry. Spatial profiles of displacement magnitude (A–C) and phase (D–F) for three different stimulus levels (40, 60, and 80 dB SPL) from one representative mouse. The stimulus frequencies were 6 kHz (A and D), 7 kHz (B and E), and 9 kHz (C and F). The thin black curves are the actual in vivo measurements from multiple points. The thick gray curves represent scaling symmetry extrapolations based on single-point measurements, made at the sites of the red vertical lines. (G and H) Tuning curve magnitudes (G) and phases (H) for 46 different longitudinal locations along the BM. Stimulation is 60 dB SPL for (G–L) and frequencies in the x axes are normalized to the BF of each tuning curve. (I and J) The coefficient of variation (CV) of the normalized tuning curves. (K and L) Averaged CV (n = 5) for displacement (K) and phase (L) against normalized frequency. Error bars are the mean ± SE. To see this figure in color, go online.
