The hippocampus has frequently been viewed as a core long-term memory structure, separate from brain structures mediating other cognitive functions such as working memory and perception. Much the same is true of other medial temporal lobe (MTL) structures such as the parahippocampal gyrus and the perirhinal cortex. Recent evidence suggests, instead, that these latter structures are also important for certain perceptual functions, leading many to propose a representational account of MTL that defines its functions in terms of what is being represented, rather than how long this representation lasts, or which psychological function is being invoked. We discuss a common framework within which perception and memory are seen as involving many, if not most, of the structures in the ventral representational stream, critically dependent on extensive feedforward and feedback processes. A variety of perceptual and memorial phenomena are discussed within this framework, and it is concluded that the hippocampus is in many ways like its neighbors in the MTL, yet has some distinct properties that account for its unique role in episodic memory.
海马体通常被视为核心的长期记忆结构，与介导其他认知功能（如工作记忆和感知）的大脑结构分离。其他内侧颞叶（MTL）结构，如旁海马回和梨状皮层，情况大致相同。最近的证据表明，这些结构对于某些感知功能也很重要，这导致许多人提出了一个关于 MTL 的代表性解释，该解释根据正在表示的内容而不是表示的持续时间或正在调用的心理功能来定义其功能。我们讨论了一个共同的框架，在这个框架中，感知和记忆被认为涉及到腹侧表示流中的许多（如果不是大多数）结构，这些结构严重依赖于广泛的前馈和反馈过程。在这个框架内讨论了各种感知和记忆现象，结论是海马体在许多方面与其在 MTL 中的邻居相似，但具有一些独特的属性，这些属性解释了其在情景记忆中的独特作用。
