Quantitative Analysis Linking Inner Hair Cell Voltage Changes and Postsynaptic Conductance Change: A Modelling Study

Figure 17

The effects of varying intensity (in dB SPL) of an input acoustic wave are investigated. Sound snippets, 200 ms in duration, were generated. Their frequencies varied: 100 Hz, 200 Hz, 300 Hz, 400 Hz, 1 kHz, and 8 kHz, all recorded at the corresponding best frequency position on the basilar membrane. The intensity of each sound snippet was increased in gradual steps of 10 dB SPL from 0 dB SPL to 140 dB SPL. Note that a “best fit” line is drawn for the 8 kHz plot because of the great variance in the model outputs.
