The ear switches from place to temporal pitch coding when harmonics stop being resolved

Evidence

The Matlab code in Section 13.6.1 produces the outputs plotted in Figure 13.12, demonstrating the effects of the different processing steps. Figure 13.12a shows the waveform of the vowel signal, and the outputs of the filter bank are shown in Figure 13.12b. The latter plot is often referred to as a cochleogram. In addition, the signals following the hair-cell processing are shown in Figure 13.12c, while the correlogram and the summary autocorrelation function are illustrated in Figure 13.12d. The last of the graphs shows a clear peak at 9 ms that corresponds to the fundamental frequency of 110 Hz of the vowel input. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1655 (#corroborates, via linked claim)
