早期（小于10毫秒的潜伏期）听觉诱发反应记录之间的顶点和中线项从人类和麻醉猫。对于单声道和双耳咔哒声，获得作为强度的函数的平均响应。然后将对每只耳朵的刺激的平均响应相加并与双耳响应进行比较。对于人类和猫，双耳响应的早期部分（通过第三个正峰）几乎与单耳响应的总和相同。与此相反，双耳响应的后期波与组合单耳响应中的那些波显著不同。这种差异，表明双耳互动，通常发现在所有的强度水平的反应，可以准确地测量。这些反应在人类和猫中的相似行为表明，这两个物种之间可能存在特定反应成分的对应关系，这可能有助于为研究人类的起源提供动物模型。
Early (less than 10 ms latency) auditory evoked responses were recorded between vertex and midline nape from humans and anesthetized cats. For both monaural and binaural clicks, averaged responses were obtained as a function of intensity. The averaged responses to stimulation of each ear were then summed and compared with the binaural response. For both humans and cats, the early portions of the binaural response (through the third positive peak) were nearly identical to those in the summed monaural responses. In contrast, the later waves of the binaural response differed significantly from those in the combined monaural responses. This difference, indicating binaural interaction, was usually found at all intensity levels for which the responses could be accurately measured. The similar behavior of these responses in both humans and cats suggests a possible correspondence of specific response components between these two species which may prove useful in providing an animal model for studying the origins ...
