越来越多的证据表明，当该事件后来被记住时，参与编码事件的大脑区域会部分重新激活。也就是说，记住一个情节的过程实际上涉及返回该情节期间存在的大脑状态。本文回顾了情景记忆和联想记忆的研究，这些研究为编码区域在后续检索过程中重新激活的主张提供了支持。在第一部分中，回顾了中性刺激与不同形式的感觉刺激或不同价态的情感刺激相关的研究。当中性刺激随后被用作检索线索时，相关的感觉和情绪处理区域被重新激活。在第二部分中，回顾了参与者采用不同策略来编码刺激的研究。当稍后检索刺激时，与不同编码策略相关的区域被重新激活。总之，这些研究表明，编码经验不仅决定了后续检索过程中哪些区域被激活，而且在编码和检索过程中相同的区域也被激活。在最后一节中，提出并讨论了有关检索期间编码区域重新激活的相关问题。
There is growing evidence that the brain regions involved in encoding an episode are partially reactivated when that episode is later remembered. That is, the process of remembering an episode involves literally returning to the brain state that was present during that episode. This paper reviews studies of episodic and associative memory that provide support for the assertion that encoding regions are reactivated during subsequent retrieval. In the first section, studies are reviewed in which neutral stimuli are associated with different modalities of sensory stimuli or different valences of emotional stimuli. When the neutral stimuli are later used as retrieval cues, relevant sensory and emotion processing regions are reactivated. In the second section, studies are reviewed in which participants employ different strategies for encoding stimuli. When the stimuli are later retrieved, regions associated with the different encoding strategies are reactivated. Together, these studies demonstrate not only that the encoding experience determines which regions are activated during subsequent retrieval, but also that the same regions are activated during encoding and retrieval. In the final section, relevant questions are posed and discussed regarding the reactivation of encoding regions during retrieval.
