Binaural interaction (BI) in brainstem-auditory-evoked responses (BSERs) was defined as any deviation from the predictions of a model that assumes two independent monaural BSER generators whose outputs are additive. Brainstem-auditory-evoked responses were recorded in response to right (R) monaural, left (L) monaural, and binaural click stimuli. The monaural BSERs were added to give the model's prediction (P) of binaurally evoked BSER (P = L + R), and this trace was then subtracted from the actual binaurally evoked response (B). The resultant difference trace (d = b - p) represents the derived BI. In each of ten guinea pigs, a strong BI was present in the peak IV region (latency = 3.5 to 4.0 ms). This interaction is probably present with interaural intensity differences of up to 40 dB and interaural time differences of up to 3 ms. Preliminary studies suggest the presence of a similar phenomenon in human BSERs.
脑干听觉诱发电位（BSERs）中的双耳相互作用（BI）被定义为与一个模型预测的任何偏差，该模型假定有两个独立的单耳BSER发生器，其输出是相加的。记录脑干听觉诱发电位以响应右（R）单耳、左（L）单耳和双耳点击刺激。将单耳BSERs相加得到模型对双耳诱发BSER的预测（P）（P = L + R），然后从实际的双耳诱发反应（B）中减去该轨迹。得到的差异轨迹（d = b - p）代表推导的BI。在十只豚鼠的每一只中，在峰IV区域（潜伏期 = 3.5至4.0毫秒）存在强烈的BI。这种相互作用可能在高达40分贝的耳间强度差异和高达3毫秒的耳间时间差异时出现。初步研究表明人类BSERs中存在类似现象。
