摘要： 综述近60 a来有关脑对双耳听觉信息整合的神经机制的研究进展.首先介绍了脑处理双耳信息的神经解剖学基础，双耳神经元的分类及其生理特性，以及双耳神经元在听觉系统的拓扑学分布研究；然后对脑处理双耳听觉信息研究的热点领域进行了重点探讨，综述了上橄榄复合体、下丘和听皮层双耳神经元对双耳时间差和双耳强度差的编码方式，以及脑通过对这些参数的编码来分析声源方位的神经生理学研究进展；最后对该领域未来研究方向作展望.

关键词: 双耳时间差, 双耳强度差, 橄榄复合体, 下丘, 听皮层

Abstract: In natural environments,human and animals percept auditory signal or sound environment by analyzing and integrating binaural sound information through the auditory system and then make their decisions. The present paper reviewed the research progress regarding the neural mechanism of binaural information integration in the brain within the last 60 years. The anatomical basis of binaural information processing,the classification and response properties of binaural neurons,and the topographic distribution of binaural neurons in the central auditory system were reviewed. Research progress and several models regarding the mechanism of binaural information processing,including the neural coding for binaural time difference and binaural level difference in the superior olive complex,inferior colliculus and auditory cortex were discussed.Future study directions on the binaural processing mechanism were also suggested.

Key words: binaural time difference, binaural level difference, superior olivary complex, inferior colliculus, auditory cortex
