Figure 8. Estimates of resonant frequency match characteristic frequency according to tonotopic location.

The resonant frequency for a hair cell expressing only those channels found in the inside-out patch was estimated using data collected from turtle hair cells (Art & Fettiplace, 1987; Wu et al. 1995) and corrected for effects of temperature. The characteristic frequency for the tonotopic position of the hair cell from which the patch was taken was calculated from the map of Jones & Jones (1995). Matched resonant and characteristic frequencies would fall along a line of identity (dotted line). A least-squares, linear regression fit to the data (dashed line) gave a slope of 0.52.
