工作记忆与情景记忆中脑区的重合与分离——从脑区定位看两者关系

Familiarity and Difference between Working Memory and Episodic Memory: To Explore Their Relationship from Brain Regions

尽管近期的研究结果认为前额叶在工作记忆和情景记忆任务中均被激活,但是仍然不清楚是否有特定的区域对两种记忆起着不同作用。对于工作记忆和情景记忆在脑区上的重合,研究者们做出了不同的解释。某些研究者认为脑区的重合反映了包含于情景记忆中的工作记忆的作用,另一些研究者则认为这种重合反映的是与工作记忆和情景记忆都有关的反省过程的性质。对此,作者提出了相应的讨论意见。

Although recent findings converge on the idea that prefrontal regions (PFC) was engaged during the working memory task and episodic long-term memory task, it remains unclear whether different regions play roles specific to working memory or episodic long-term memory. Researchers argued about the relationship between working memory and episodic long-term memory and supported different views. Some researchers support the view that prefrontal activation during episodic memory reflects the recruitment of specific working memory processes in the service of episodic memory. The others raise the possible that the same prefrontal regions implement reflective processes that support both working memory and episodic long-term memory. The present article supports the discussion to the questions above.
