研究人员检查了成功记忆检索过程中意识意识的神经相关性。在认知测试中，受试者表明他们是否有意识地回忆了之前出现过某个单词的事件（记住），或者他们是否根据在没有回忆的情况下熟悉该单词的情况来识别它（知道）。早期脑电图θ带的同步预示着认知，而后来的记忆则预示着。此外，还发现早期和晚期事件相关电位分别可以预测认知和记忆。结果表明，θ 同步的时间动态与记忆检索相关的特定意识体验有关。 (C) 2001 Elsevier Science B.V. 保留所有权利。
The neural correlates of conscious awareness during successful memory retrieval were examined. In a recognition test, subjects indicated whether they consciously recollected the event in which a word was earlier presented (Remembering), or whether they recognized it on the basis that it was familiar in the absence of recollection (Knowing). An early EEG synchronization in the theta band predicted knowing, and a later remembering. Moreover, early and late event-related potentials were also found to predict knowing and remembering, respectively. The results indicate that the temporal dynamics of theta synchronization are related to the particular conscious experiences associated with memory retrieval. (C) 2001 Elsevier Science B.V.
