Examples of diverse responses to HCTs by non-HTNs. (A–D) Four examples of non-HTNs. (Lower Left) Spectral components of HCTs (y axis: $f_0$; x axis: frequency of individual harmonics), (Lower Center) raster plot of responses to HCTs in Lower Left, and (Lower Right) averaged firing rates at different $f_0$ derived from the raster plot. In the HCT spectra plots, each row represents an HCT, with a dot representing a harmonic in the stimulus. The black dashed lines indicate BF, corresponding to the frequency with the maximal firing rate in the pure tone tuning (Upper). Error bars represent SD of the mean firing rate.
