休息时大脑的连通性可以反映个体差异并影响行为结果，包括记忆。本研究调查了文化如何影响内侧颞叶区域的功能连接。在这项研究中，46 名美国人和 59 名东亚人在对物体图片进行编码后完成了静息状态扫描。为了研究静息状态功能连接的跨文化差异，选择左侧海马旁回（前区和后区）和左侧海马作为种子区域。选择这些区域是因为它们之前参与了成功编码详细记忆过程中的文化差异的研究。结果显示，与美国人相比，东亚人的左后海马旁回与颞枕区的连通性更强，与东亚人相比，美国人的左后海马旁回与顶枕区的连通性更强。东亚人的左前海马旁回与颞区的连通性比美国人更强，美国人的左前海马旁回与额叶区的连通性比东亚人更强。尽管连通性与记忆表现无关，但模式确实与文化价值观有关。独立自我构念的程度和传统的主观价值与涉及左前海马旁回的功能连接相关。研究结果是根据记忆巩固或更普遍的特征或基于状态的过程（例如整体处理与分析处理）的潜在文化差异进行讨论的。
Connectivity of the brain at rest can reflect individual differences and impact behavioral outcomes, including memory. The present study investigated how culture influences functional connectivity with regions of the medial temporal lobe. In this study, 46 Americans and 59 East Asians completed a resting state scan after encoding pictures of objects. To investigate cross-cultural differences in resting state functional connectivity, left parahippocampal gyrus (anterior and posterior regions) and left hippocampus were selected as seed regions. These regions were selected, because they were previously implicated in a study of cultural differences during the successful encoding of detailed memories. Results revealed that left posterior parahippocampal gyrus had stronger connectivity with temporo-occipital regions for East Asians compared with Americans and stronger connectivity with parieto-occipital regions for Americans compared with East Asians. Left anterior parahippocampal gyrus had stronger connectivity with temporal regions for East Asians than Americans and stronger connectivity with frontal regions for Americans than East Asians. Although connectivity did not relate to memory performance, patterns did relate to cultural values. The degree of independent self-construal and subjective value of tradition were associated with functional connectivity involving left anterior parahippocampal gyrus. Findings are discussed in terms of potential cultural differences in memory consolidation or more general trait or state-based processes, such as holistic versus analytic processing.
