Discharge patterns from cochlear nerve fibers contain important information about acoustic stimuli and encoding schemes of the peripheral auditory system. Yet these patterns are distorted due to refractory or dead time effects. By modeling discharges from peripheral auditory nerves as a self-exciting Poisson process, the effects of dead time on a poststimulus time histogram can be determined, assuming the recovery time does not depend on acoustic stimuli. If the recovery function is known, a closed-form formula is available to remove the dead time distortions from the poststimulus time histogram.
耳蜗神经纤维的放电模式包含有关声学刺激和外周听觉系统编码方案的重要信息。然而,由于不应期或死区时间效应,这些模式会被扭曲。通过将外周听觉神经的放电建模为自激泊松过程,在假设恢复时间不依赖于声学刺激的情况下,可以确定死区时间对刺激后时间直方图的影响。如果恢复函数已知,则有一个封闭形式的公式可用于消除刺激后时间直方图中的死区时间失真。
