The hippocampal complex and neocortex are both integrally important in memory function, in particular as regards memory for episodes and knowledge about the world that is derived from them. It is traditionally assumed that the role of the hippocampus is time-limited, after which retrieval of episodic memory depends only upon neocortical stores. A number of lines of evidence indicate that this traditional view is incorrect. We propose that the hippocampal complex is always necessary for retrieval of episodes and their contextual frame, and that hippocampal-neocortical interactions contribute instead to the extraction of semantic information to be stored in the neocortex.
海马复合体和新皮层在记忆功能中都起着不可或缺的重要作用，特别是在情景记忆以及从中衍生出的关于世界的知识方面。传统观点认为，海马体的作用是有时间限制的，在此之后，情景记忆的提取仅依赖于新皮层的存储。然而，大量证据表明这一传统观点是错误的。我们认为，海马复合体对于情景及其背景框架的提取始终是必要的，而海马体与新皮层之间的相互作用则有助于提取要存储在新皮层中的语义信息。
