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.

概念形成是一个计算性认知过程。

海马和内嗅皮层形成认知图，它们代表多维空间内记忆之间的关系。尽管长期以来已提出这些关系图有助于情节记忆，但最近的工作表明它们也通过表示用于区分相关概念的相关特征来支持概念形成。可以通过内侧前额叶皮层来完善认知图，内侧前额叶皮层根据其行为相关性选择要表示的维度。海马模式的完成，这对于恢复情节性记忆至关重要，也可能有助于将现有概念推广到新的样本中。在海马认知图中的导航（由内嗅皮层中的网格编码指导）可能通过事件元素或概念特征的重组而有助于想象。
