摘要： 人和动物对声源方位的感知和心理确定建立在神经生理基础之上, 得到了大量来自神经细胞电生理研究证据的支持。听中枢神经元可通过比较到达两耳声信号的不同特征和参量来体现其精确的声源定位能力。研究表明, 声源定位过程是听觉系统复杂综合作用的结果, 听觉中脑核团-下丘在这一过程中起着重要作用, 下丘中大量双耳听觉反应神经元可编码声音(源)方位信息, 甚至双侧下丘间的联合投射也有可能参与双耳听觉反应的调制。

Abstract: The neural basis of locating and psychologically determining sound source has been demonstrated by a lot of neural electrophysiological studies. Sound source location has resulted from the complicated integration in auditory system. The great ability of auditory central neuron in sound location is achieved by comparing the difference in characters of sound signals arrived at two ears. The auditory midbrain nucleus, inferior colliculus (IC), plays an important role in processing the information of sound location. Many binaural response neurons in one IC may decode the sound location information, moreover interactions between two ICs are likely to modulate the binaural auditory responses.

Key words: auditory midbrain, sound localization, neural modulation
