通过对平均诱发反应使用单极记录，警戒任务中的检测信号与未检测信号以及非信号所不存在的晚期正分量相关联。双极记录掩盖了与检测到的信号相关联的晚期正分量。数据表明，晚期的积极成分代表了与评估不可预测的刺激变化相关的大脑过程。
With the use of monopolar recordings for averaged evoked responses, detected signals in a vigilance task are associated with a late positive component which is absent for undetected signals as well as nonsignals. Bipolar recordings obscure the late positive component associated with detected signals. The data suggest that the late positive component represents cerebral processes associated with evaluation of unpredictable changes in stimulation.
