The present study assessed the relationship between stimulus-induced electroencephalographic (EEG) theta activity (4-7 Hz) and the endogenous component P300 of auditory event-related potentials (ERPs) using a developmental model. ERPs were recorded from 50 children (6-11 years old) for oddball target and frequent non-target stimuli and analysed in the time and frequency domains. The latency of the maximal theta response of the digitally filtered (4-7 Hz) ERPs was evaluated with respect to age and scalp topography effects. The maximal theta response latency at Cz and Pz decreased with increasing age and entirely predicted the developmental latency reduction of the parietal P400-700 (P3b) component in children.
本研究使用一种发育模型评估了刺激诱发的脑电图（EEG）θ波活动（4 - 7赫兹）与听觉事件相关电位（ERP）的内源性成分P300之间的关系。记录了50名儿童（6 - 11岁）对奇偶数目标刺激和频繁出现的非目标刺激的ERP，并在时域和频域进行分析。针对年龄和头皮地形图效应，评估了数字滤波（4 - 7赫兹）ERP的最大θ波反应潜伏期。Cz和Pz处的最大θ波反应潜伏期随年龄增长而缩短，并且完全预测了儿童顶叶P400 - 700（P3b）成分发育过程中的潜伏期缩短情况。
