在人类中，情节记忆最常见的定义是回忆的主观体验，这对动物的情节记忆识别提出了重大挑战。在这里，我们认为情节记忆还有其他几个独特的特性，可以在动物和人类身上进行客观评估，对这些特性的研究为深入了解情节记忆的潜在机制提供了洞察力。我们重点关注最近在这个实验室积累的证据表明，大鼠的识别涉及一个阈值提取过程，类似于在人类情景回忆中观察到的过程。此外，老鼠还能记住独特事件的时间顺序，这是人类生动情节记忆的特征。此外，老鼠结合了“何时”和“何处”事件发生的元素，以及记忆中事件的流动，以区分具有重叠特征的记忆，这也是人类情节记忆的特征。最后，所有这些能力都依赖于海马体，海马体在人类情节记忆中也发挥着关键作用。这一发现的结合有力地表明，动物具有与人类情节回忆相同的基本信息处理功能。(C)2005 Elsevier Inc.保留所有权利。
In humans, episodic memory is most commonly defined as the subjective experience of recollection, presenting a major challenge to the identification of episodic memory in animals. Here we take the position that episodic memory also has several other distinctive qualities that can be assessed objectively in animals, as well as humans, and the examination of these properties provides insights into underlying mechanisms of episodic memory. We focus on recent evidence accumulated in this laboratory indicating that recognition in rats involves a threshold retrieval process, similar to that observed in human episodic recall. Also, rats can remember the temporal order of unique events, characteristic of the replay of vivid episodic memories in humans. Furthermore, rats combine elements of '' when '' and '' where '' events occur, as well as the flow of events within a memory, to distinguish memories that share overlapping features, also characteristic of human episodic memory. Finally, all of these capacities are dependent on the hippocampus, which also plays a critical role in human episodic memory. This combination of findings strongly suggests that animals have the same fundamental information processing functions that underlie episodic recall in humans. (c) 2005 Elsevier Inc.
