In this study, differences between electrically evoked whole-nerve action potential (EAP) and electrically evoked auditory brainstem response (EABR) measurements within Nucleus CI24R cochlear implant recipients were evaluated. Precurved modiolus-hugging internal electrode arrays, such as the CI24R, are designed to provide more direct stimulation of neural elements of the modiolus. If the electrode array is closer to the modiolus, electrically evoked and behavioral levels might be lower than were previously recorded for the straight electrode array, the CI24M. EAP and EABR growth functions and behavioral levels were obtained for 10 postlingually deafened adults. Results revealed no significant differences between EAP and EABR threshold levels, and these levels were not significantly lower than those obtained using the CI24M.
在本研究中，对Nucleus CI24R人工耳蜗植入受者的电诱发全神经动作电位（EAP）和电诱发听性脑干反应（EABR）测量之间的差异进行了评估。预弯的蜗轴环抱式内部电极阵列，如CI24R，旨在更直接地刺激蜗轴的神经元件。如果电极阵列更靠近蜗轴，电诱发水平和行为水平可能低于先前使用直电极阵列CI24M所记录的水平。对10名语后聋成年人获得了EAP和EABR的增长函数以及行为水平。结果显示，EAP和EABR阈值水平之间无显著差异，且这些水平并不显著低于使用CI24M所获得的水平。
