It has long been hypothesized that individual recollection fits collective memory. To look for a collective schema, we analysed the content of 30 years of media coverage of World War II on French national television. We recorded human brain activity using functional magnetic resonance imaging as participants recalled World War II displays at the Caen Memorial Museum following an initial tour. We focused on the medial prefrontal cortex, a key region for social cognition and memory schemas. The organization of individual memories captured using the distribution of the functional magnetic resonance imaging signal in the dorsal part of the medial prefrontal cortex was more accurately predicted by the structure of the collective schema than by various control models of contextual or semantic memory. Collective memory, which exists outside and beyond individuals, can also organize individual memories and constitutes a common mental model that connects people's memories across time and space.

集体记忆塑造了内侧前额叶皮层中单个记忆的组织。

长期以来一直有人认为个人回忆适合集体记忆。为了寻找一个集体模式，我们分析了法国国家电视台30年第二次世界大战媒体报道的内容。参与者在初次参观后回忆起第二次世界大战在卡昂纪念馆的展览时，我们使用功能磁共振成像记录了人类的大脑活动。我们专注于内侧前额叶皮层，这是社交认知和记忆模式的关键区域。使用功能性磁共振成像信号在内侧前额叶皮层背侧的分布所捕获的单个记忆的组织，通过集合模式的结构比通过上下文或语义记忆的各种控制模型可以更准确地预测。集体记忆
