The brain-stem electric responses of the cat evoked by a short 4 kHz tone burst have been differentially recorded between vertex and both ipsilateral and contralateral ear electrodes. Six vertex-positive waves can be recognised in both recordings. Animals with hereditary unilateral anacusis were studied in order to avoid cross-stimulation of the opposite ear. The cochlear microphonic and summating potential can be readily recorded in young animals, occur simultaneously in both tracings, and show polarity inversion at the contralateral electrode. The later neural potentials have the same polarity and practically identical latencies in the ipsilateral and contralateral recordings, whilst the first three brain-stem waves show approximate polarity inversion and variable latency relationships in the two recording situations. It is concluded that none of the brain-stem waves represents electric activity from a discrete generator.
通过在猫的头顶以及同侧和对侧耳部电极之间进行差分记录，记录了由短4kHz纯音脉冲诱发的猫的脑干电反应。在两个记录中都可以识别出六个头顶正向波。为了避免对侧耳的交叉刺激，对患有遗传性单侧耳聋的动物进行了研究。耳蜗微音电位和总和电位在幼小动物中很容易记录到，在两个记录中同时出现，并且在对侧电极处显示极性反转。在同侧和对侧记录中，后期神经电位具有相同的极性和几乎相同的潜伏期，而在前三个脑干波中，在两种记录情况下显示出近似的极性反转和可变的潜伏期关系。得出的结论是，没有一个脑干波代表来自离散发生器的电活动。
