海马体和内嗅皮层形成了认知地图,代表了多维空间中记忆之间的关系。虽然这些关系图长期以来一直被认为有助于情景记忆,但最近的研究表明,它们也通过表示相关特征来区分相关概念,从而支持概念的形成。认知图可以通过内侧前额叶皮质进行细化,它根据行为相关性选择维度来表示。海马区模式的完成对于情节记忆的提取是至关重要的,也可能有助于将现有概念推广到新的样本。由内嗅皮层网格编码引导的海马区认知地图导航,可能通过事件元素或概念特征的重组来促进想象力。
Hippocampus and entorhinal cortex form cognitive maps that represent relations among memories within a multidimensional space. While these relational maps have long been proposed to contribute to episodic memory, recent work suggests that they also support concept formation by representing relevant features for discriminating among related concepts. Cognitive maps may be refined by medial prefrontal cortex, which selects dimensions to represent based on their behavioral relevance. Hippocampal pattern completion, which is critical for retrieval of episodic memories, may also contribute to generalization of existing concepts to new exemplars. Navigation within hippocampal cognitive maps, which is guided by grid coding in entorhinal cortex, may contribute to imagination through recombination of event elements or concept features.
