| The temperature sensitivity of weak periodic signal detection has been studied via numerical simulations for bushy cells in auditory midbrain. The dependence of the spiking threshold of the signal upon its frequency and temperature could account for the temperature sensitivity. In the presence of the effect of frequency and temperature on the spiking threshold of the signal, our analyses reveal that there exists a temperature sensitivity range, and as the frequency of the signal decreasing, the sensitivity range is wider. These findings imply that there is a physiological temperature range which is benefit for the information processing in auditory system, and it processes the signal at lower frequency well in a wider temperature range than at higher frequency. |
