ABSTRACT

This review mainly explores less-reported neural markers to speech-evoked contrasts in children with cochlear implants (CI). Databases and electronic journals were searched with keywords of “mismatch responses” AND “positive mismatch response” (p-MMR) AND “late discriminate negativity” (LDN). P-MMR likely is as a measurement of brain immaturity in CI children while the developmental trajectories of LDN remain unexplained in older CI children. In CI children, there is a p-MMR-MMN-LDN sequence to speech stimuli developmentally. Whereas these aforementioned neural responses anticipate developmental changes in CI groups, it is still uncertain about the cutoff age for disappearance of p-MMR and LDN.

摘要

本综述主要探讨了较少报道的人工耳蜗植入 (CI) 儿童语音诱发对比的神经标记。用关键词“mismatch response”和“positive mismatch response”（p -MMR）和“late discriminate negativity”（LDN）搜索数据库和电子期刊。P -MMR 可能是 CI 儿童大脑不成熟的衡量标准，而 LDN 的发育轨迹在年龄较大的 CI 儿童中仍未得到解释。在 CI 儿童中，有一个p -MMR-MMN-LDN 序列可在发育过程中产生言语刺激。尽管上述这些神经反应预测了 CI 组的发育变化，但仍然不确定p -MMR 和 LDN 消失的截止年龄。
