It has recently been observed that the brain network supporting recall of episodic memories shares much in common with other cognitive functions such as episodic future thinking, navigation and theory of mind. It has been speculated that 'self-projection' is the key common process. However, in this Opinion article, we note that other functions (e.g. imagining fictitious experiences) not explicitly connected to either the self or a subjective sense of time, activate a similar brain network. Hence, we argue that the process of 'scene construction' is better able to account for the commonalities in the brain areas engaged by an extended range of disparate functions. In light of this, we re-evaluate our understanding of episodic memory, the processes underpinning it and other related cognitive functions.
最近有研究发现，支持情景记忆回忆的大脑网络与其他认知功能有许多共同之处，如情景未来思维、导航和心理理论。有人推测，“自我投射”是关键的共同过程。然而，在这篇观点文章中，我们注意到其他功能（如想象虚构经历）与自我或主观时间感并无明确关联，却激活了类似的大脑网络。因此，我们认为“场景构建”过程更能解释一系列不同功能所涉及的大脑区域的共性。据此，我们重新评估了对情景记忆、其背后的过程以及其他相关认知功能的理解。
