Abstract

We examined habituation and dishabituation of evoked K-complexes (equivalent to auditory event-related potentials) during sleep. Habituation is investigated by presenting trains of stimuli with a 5 sec inter-stimulus interval and a 4 min inter-train interval. Habituation is complete by the third identical stimulus in a train and dishabituation occurs after deviant stimuli and after the inter-train interval. Although there are morphological differences between K-complexes in sleep and auditory event-related potentials in wakefulness, they share the phenomenon of habituation to repetitive events.

摘要

我们研究了睡眠期间诱发的K复合波（等同于听觉事件相关电位）的习惯化和去习惯化。通过以5秒的刺激间隔和4分钟的组间间隔呈现一连串刺激来研究习惯化。在一组刺激中的第三个相同刺激时习惯化完成，并且在异常刺激后以及组间间隔后出现去习惯化。尽管睡眠中的K复合波与清醒时的听觉事件相关电位在形态上存在差异，但它们都具有对重复事件的习惯化现象。
