中文摘要：

光学耳蜗利用激光脉冲作为激励源触发听觉神经产生听觉，与传统电子耳蜗相比，在触发精度和抗干扰等方面具有独特优势。尽管光学耳蜗动物实验取得了大量有价值的研究结果，但是激光触发听觉的机制仍在探索当中，需要开展更深入的研究。本文首先对近几年国内外学者在该领域的新成果做了简要概述，探讨了几种可能的激光触发机制，然后针对目前研究中存在的问题提出了几种新的研究方案，这些新方案可能有助于进一步揭示激光触发的机制。

英文摘要：

Optical cochlear implant has been occuring as a new cochlear implant which utilizes laser pulses to stimulate heating. Compared to electronic cochlear implant, it has demonstrated higher spatial selectivity and less radiation scattering, which could lead to higher fidelity cochlear prostheses. At present, most investigations have focused on experiments in vivo. Although a lot of exciting results have been obtained, the mechanisms of laser stimulation is still open. In this paper, a brief review on the recent new findings of optical cochlear implant is given, and possible mechanisms are discussed. In the end, new experimental proposals are suggested which could help to explore the mechanisms of laser-cochlea stimulation.
