BAERs from 16 subjects during 3 sessions varied in the latency or amplitude of some components depending upon level of arousal as indicated by EEG patterns. There was a general tendency for activation to produce the fastest responses with the largest amplitudes and for drowsiness to produce the slowest responses with the smallest amplitudes. The latency of P2 was significantly prolonged during drowsiness, relative to those during relaxation or activation. For right-ear stimulation, P5 latency was longest during drowsiness, and shortest during activation while for left-ear stimulation the shortest latency occurred during relaxation. The amplitudes of Wave II and Wave VII were significantly smaller during drowsiness than during activation. Although the differences were below the level of clinical significance, the data indicate a modification in the characteristics of brainstem transmission as a function of concurrent activity in other brain areas.
16名受试者在3个阶段的脑干听觉诱发电位（BAERs）中，某些成分的潜伏期或波幅会因脑电图模式所显示的觉醒水平而有所不同。一般趋势是，激活状态下会产生最快的反应且波幅最大，而困倦状态下会产生最慢的反应且波幅最小。与放松或激活状态相比，困倦状态下P2的潜伏期显著延长。对于右耳刺激，P5潜伏期在困倦状态下最长，在激活状态下最短；而对于左耳刺激，最短潜伏期出现在放松状态。与激活状态相比，困倦状态下波II和波VII的波幅显著更小。尽管这些差异低于临床意义水平，但数据表明脑干传导特征会因其他脑区的并发活动而发生改变。
