本研究的目的是确定神经适应对Nucleus 24人工耳蜗植入者的时间整合行为测量的影响。由于听觉神经是中央时间整合器的输入，因此，很大程度的听觉神经适应将减少时间整合的量。神经适应性通过跟踪响应于不同持续时间的1000-pps双相脉冲串的电诱发复合动作电位（ECAP）的幅度变化来测量。在阈上和阈下水平的自适应程序测量时间整合。虽然不同程度的神经适应和时间整合的个体之间观察到，这项调查的结果显示，神经适应和心理物理措施的时间整合的程度之间没有相关性。(c)2005年美国声学学会。
The objective of this study was to determine the impact that auditory-nerve adaptation has on behavioral measures of temporal integration in Nucleus 24 cochlear implant recipients. It was expected that, because the auditory nerve serves as the input to central temporal integrator, a large degree of auditory-nerve adaptation would reduce the amount of temporal integration. Neural adaptation was measured by tracking amplitude changes of the electrically evoked compound action potential (ECAP) in response to 1000-pps biphasic pulse trains of varying durations. Temporal integration was measured at both suprathreshold and threshold levels by an adaptive procedure. Although varying degrees of neural adaptation and temporal integration were observed across individuals, results of this investigation revealed no correlation between the degree of neural adaptation and psychophysical measures of temporal integration.
