The objective of the study was to investigate the potential for clinical application of neural response imaging (NRI) cochlear mapping. Cochlear mapping was performed at each fitting session up to at least six months following initial fitting. Stimulation was delivered to one electrode site. NRI was recorded from each of the remaining sites. The procedure was repeated for apical, medial and basal stimulation sites, stimulating at subjective threshold and most comfortable levels. Responses were obtained in five out of six subjects and are discussed in terms of: reproducibility, quality, changes over time. Cochlear mapping provided repeatable data that gave interesting insights into the implanted cochlea. Further work is required to determine whether this approach could contribute to programme optimisation.
该研究的目的是调查神经反应成像（NRI）耳蜗图谱的临床应用潜力。在初次调试后的每次调试过程中进行耳蜗图谱绘制，至少持续六个月。刺激施加于一个电极位点，从其余每个位点记录NRI。对尖部、中部和基部刺激位点重复该过程，分别在主观阈值和最舒适水平进行刺激。六名受试者中有五名获得了反应，并从可重复性、质量、随时间的变化等方面进行了讨论。耳蜗图谱提供了可重复的数据，为植入的耳蜗提供了有趣的见解。还需要进一步开展工作，以确定这种方法是否有助于优化编程。
