编码和检索过程之间重叠的概念是情景记忆认知理论的核心，但迄今为止，大多数功能神经影像研究都强调这些过程之间的差异。在本研究中，通过分析不同类型事件信息的编码和检索的正电子发射断层扫描（PET）研究的数据，研究了编码和检索过程之间的重叠。使用联合分析，我们的具体目标是识别激活模式的重叠，以编码和检索三类事件信息：项目、时间和空间。研究发现，空间信息的编码和检索都会激活双侧后顶叶区域。此外，项目编码和检索与右颞极的活动增加相关，而时间编码和检索与左下额叶和左下颞区的活动增加相关。这些发现表明，当从记忆中检索特定的情景信息时，参与编码相同信息的区域就会参与进来。显微镜。资源。技术。 51:39–44, 2000。© 2000 Wiley-Liss, Inc.
The notion of overlap between encoding and retrieval processes is central in cognitive theories of episodic memory, but to date most functional neuroimaging studies have emphasized differences between these processes. In the present study, overlap between encoding and retrieval processes was investigated by analyzing data from a positron emission tomography (PET) study of encoding and retrieval of different kinds of event information. Using a conjunction analysis, we specifically aimed at identifying overlap in activation patterns for encoding and retrieval of three classes of event information: item, temporal, and spatial. It was found that both encoding and retrieval of spatial information activated posterior parietal areas bilaterally. In addition, item encoding and retrieval were associated with increased activity in the right temporal pole, and temporal encoding and retrieval with left inferior frontal and left inferior temporal regions. These findings suggest that when specific episodic information is retrieved from memory, regions involved in encoding of the same information are engaged. Microsc. Res.
