对人类言语记忆功能的行为学研究导致了情景记忆和语义记忆的初步定义。情节记忆的神经机制的完整模型必须包括对人类能从经验中回忆起的一切进行编码和心理重建的能力。本文提出了在更广泛的认知背景下解决情景记忆编码和回忆的复杂性所必需的新模型特征，以及可能有助于这种更广泛记忆范围的神经元的功能特性。许多情节记忆模型用一系列向量代表世界的单个快照，但完整的模型必须代表复杂的功能，编码和检索多个刺激特征之间的关系，跨越空间和时间在多个层次尺度上。情节记忆不仅涉及个体在情节中经历事件的空间和时间，还包括神经生理学数据中显示的特征，如速度、方向、边界和物体的编码。情节记忆不仅包括单个智能体的时空轨迹，还包括环境中遇到的其他智能体和物体的时空轨迹片段，这些片段与编码物体和边界的感觉特征的位置和角度的数据一致。我们将讨论海马体和内嗅皮层中情景记忆回路与分布的新皮质回路的潜在相互作用，这些回路必须代表人类认知的所有特征。
Behavioral research in human verbal memory function led to the initial definition of episodic memory and semantic memory. A complete model of the neural mechanisms of episodic memory must include the capacity to encode and mentally reconstruct everything that humans can recall from their experience. This article proposes new model features necessary to address the complexity of episodic memory encoding and recall in the context of broader cognition and the functional properties of neurons that could contribute to this broader scope of memory. Many episodic memory models represent individual snapshots of the world with a sequence of vectors, but a full model must represent complex functions encoding and retrieving the relations between multiple stimulus features across space and time on multiple hierarchical scales. Episodic memory involves not only the space and time of an agent experiencing events within an episode but also features shown in neurophysiological data such as coding of speed, direction, boundaries, and objects. Episodic memory includes not only a spatio-temporal trajectory of a single agent but also segments of spatio-temporal trajectories for other agents and objects encountered in the environment consistent with data on encoding the position and angle of sensory features of objects and boundaries. We will discuss potential interactions of episodic memory circuits in the hippocampus and entorhinal cortex with distributed neocortical circuits that must represent all features of human cognition.
