以往的研究表明，电极配置对耳蜗植入患者的语音识别评分有很大影响。关于这些效应机制的不同假设都涉及到诱发神经活动的空间模式。人类听觉皮层水平的PET成像将用于确定不同配置的激活空间模式，并将这些模式与正常听力受试者对声刺激的反应进行比较。
英文摘要
Previous studies have shown that electrode configuration has a large effect on speech recognition scores of deaf patients with cochlear implants (auditory prostheses). Different hypotheses about the mechanisms of these effects all refer to the spatial pattern of evoked neural activity. PET imaging at the level of human auditory cortex will be used to determine the spatial pattern of activation for the different configurations and to compare these patterns with those found in response to acoustic stimulation in normal hearing subjects.
