作者：Wernick，JS; Starr，A|摘要：副核，或称上级橄榄复合体的内侧核，是经典上行听觉通路中接收双侧输入的第一个核团。副核的解剖结构和电生理反应均表明它是双耳信号处理的部位。副核的细胞已经被证明对双耳呈现的咔嗒声的耳间时间和强度差异（5，6）以及双耳呈现的音调的耳间相位关系（11）做出反应。由短声和纯音刺激诱发的副核的场电位与双耳突触输入的解剖分布相关（3，5，17）。Rosenzweig和Amon（13）发现了上级橄榄复合体对双耳呈现的滴答声的慢波反应中双耳相互作用的证据。本研究通过分析双耳纯音诱发的上级橄榄复合体的场电位，进一步阐明双耳交互作用的机制。
Author(s): Wernick, JS; Starr, A | Abstract: THE ACCESSORY, or medial nucleus of the superior olivary complex is the first nucleus in the classical ascending auditory pathway that receives bilateral input. Both the anatomical structure and electrophysiological responses of the accessory nucleus suggest that it is a locus of binaural signal processing. The cells of the accessory nucleus have been shown to be responsive to interaural time and intensity disparities of binaurally presented clicks (5, 6) and to the interaural phase relations of binaurally presented tones (11). The field potentials of the accessory nucleus evoked by click and pure-tone stimuli have been correlated with the anatomical distribution of synaptic input from the two ears (3, 5, 17). Evidence of binaural interaction in the slowwave responses of the superior olivary complex to binaurally presented clicks was found by Rosenzweig and Amon (13). In the present study the field potentials of the superior olivary complex evoked by binaurally presented pure tones were analyzed to define further the mechanisms of binaural interaction.
