A number of electrical potentials can be recorded from the human scalp following acoustic stimulation. The potentials which occur within 10 msec of the stimulus onset have been termed the brain stem auditory evoked potentials (BAEPs). Latency appears to be the most stable measure and in consequence knowledge of the exact limits of normal latency of each wave is important. In this study the effects of ipsilateral and contralateral stimulation on BAEP latencies have been investigated in 23 normal subjects. The exact limits of normal latency of each wave have been established. It has been shown that significant latency differences exist between ipsilateral and contralateral stimulation. Possible hypotheses are put forward to explain the findings which demonstrate that different neural pathways are followed by ipsilateral and contralateral stimuli and that their respective responses can be investigated separately in man using BAEP recordings.
在声音刺激后，可以从人类头皮记录到多种电位。在刺激开始后10毫秒内出现的电位被称为脑干听觉诱发电位（BAEP）。潜伏期似乎是最稳定的测量指标，因此了解每个波正常潜伏期的确切范围很重要。在这项研究中，对23名正常受试者进行了同侧和对侧刺激对BAEP潜伏期影响的研究。已经确定了每个波正常潜伏期的确切范围。结果表明，同侧和对侧刺激之间存在显著的潜伏期差异。提出了可能的假设来解释这些发现，这些发现表明同侧和对侧刺激遵循不同的神经通路，并且可以在人体中使用BAEP记录分别研究它们各自的反应。
