20例正常新生儿记录同侧和对侧中间成分AERs(8~90ms)。在10、30和50dBHL时，分别用500-HZ或3000-HZ的单频短音诱发AERS。在无声控制条件下，也获得了AERS。总体而言，潜伏期随刺激水平的增加而缩短，波幅随刺激水平的增加而增加。对500赫兹短音的反应大于对3000赫兹的反应。这一结果与从成年人身上获得的结果相似。然而，新生儿的中间成分与成人的不同之处在于超过60ms的脑电活动的贡献很小，以及同侧和对侧AERs之间的不对称性。
Ipsilateral and contralateral middle-component AERs (8-90 ms) were recorded from 20 normal neonates. AERs were elicited with either 500-Hz or 3000-Hz tone-pips presented monotically at 10, 30, and 50 dB HL. AERs also were obtained for silent control conditions. In general, latencies decreased and amplitudes increased with increasing stimulus level. Responses to 500-Hz tone-pips were larger than those for 3000 Hz. The results are similar to those obtained from adults. The neonates' middle-components, however, differ from those of adults in terms of the small contribution of the electroencephalic activity beyond 60 ms, and in the asymmetry between the ipsilateral and contralateral AERs.
