Spatial navigation and memory are often seen as heavily intertwined at the cognitive and neural levels of analysis. We review models that hypothesize a central role for the medial temporal lobes, including the hippocampus, in both navigation and aspects of memory, particularly allocentric navigation and episodic memory. While these models have explanatory power in instances in which they overlap, they are limited in explaining functional and neuroanatomical differences. Focusing on human cognition, we explore the idea of navigation as a dynamically acquired skill and memory as an internally driven process, which may better account for the differences between the two. We also review network models of navigation and memory, which place a greater emphasis on connections rather than the functions of focal brain regions. These models, in turn, may have greater explanatory power for the differences between navigation and memory and the differing effects of brain lesions and age.
空间导航和记忆在认知和神经分析层面上通常被视为紧密交织在一起的。我们回顾了一些假设内侧颞叶（包括海马体）在导航和记忆方面（特别是非定域导航和情景记忆）中起核心作用的模型。虽然这些模型在重叠的情况下具有解释力，但它们在解释功能和神经解剖学差异方面存在局限性。我们专注于人类认知，探讨将导航视为一种动态习得的技能和记忆作为一种内在驱动的过程的观点，这可能更好地解释两者之间的差异。我们还回顾了导航和记忆的网络模型，这些模型更加强调连接而不是焦点脑区的功能。这些模型反过来可能对导航和记忆之间的差异以及大脑损伤和年龄的不同影响具有更大的解释力。
