50多年的研究已经使人们普遍认为海马体有助于记忆，但这段时间以来，海马体功能的理论一直存在重大分歧。一些研究人员认为海马体在情景和陈述性记忆中起着广泛的作用，而另一些人则认为海马体在空间认知地图和导航的创造中起着特定的作用。虽然这两种观点都有其优点，但都不能完全解释海马的功能。在最近试图在这些观点之间建立桥梁的综述的指导下，我们建议通过从托尔曼（1948）的认知地图的原始概念的角度探索海马体功能来实现调和，认知地图是在所有认知领域组织经验和指导行为。我们强调最近对动物和人类的研究表明，海马体网络支持广泛的认知地图领域，这些网络在情境相关的地图中组织特定的经历，网络活动模式反映了通过认知地图引导的行为。这些结果与将海马体概念化为在空间、时间和关联背景的多维认知地图中组织传入信息的海马体功能理论的框架是一致的。
More than 50 years of research have led to the general agreement that the hippocampus contributes to memory, but there has been a major schism among theories of hippocampal function over this time. Some researchers argue that the hippocampus plays a broad role in episodic and declarative memory, whereas others argue for a specific role in the creation of spatial cognitive maps and navigation. Although both views have merit, neither provides a complete account of hippocampal function. Guided by recent reviews that attempt to bridge between these views, here we suggest that reconciliation can be accomplished by exploring hippocampal function from the perspective of Tolman's (1948) original conception of a cognitive map as organizing experience and guiding behavior across all domains of cognition. We emphasize recent studies in animals and humans showing that hippocampal networks support a broad range of domains of cognitive maps, that these networks organize specific experiences within the contextually relevant map, and that network activity patterns reflect behavior guided through cognitive maps. These results are consistent with a framework that bridges theories of hippocampal function by conceptualizing the hippocampus as organizing incoming information within the context of a multidimensional cognitive map of spatial, temporal, and associational context.
