FIG. 4.
The firing patterns of ANF G237u5-3 (also shown in Figure 3). A Threshold FTC. B Interspike interval (ISI) histogram of the neural responses aggregated within the tip region, from the CF of 6.34 kHz to 10.16 kHz. C ISI histogram of the neural responses aggregated within the plateau region, from 10.87 kHz to 21.36 kHz. D–F ISI histogram, period histogram and raster plot at the CF and two plateau frequencies. In the raster plots, the stimulus waveform (arbitrary magnitude) and duration are depicted in red on the bottom of the raster plots to provide a visual reference to when the stimulus tone was turned on and off. There were five repetitions at every stimulus level.
