在本文中，我们提出了一种机制，新皮层可以用来存储序列的模式。存储和调用序列对于进行预测、识别基于时间的模式和生成行为是必要的。由于这些任务是新皮质的主要功能，因此存储和回忆基于时间的序列的能力可能是许多（如果不是全部）皮质区域的关键属性。在此之前，我们已经提出新皮层可以被建模为一个记忆区域的层次结构，每个区域都学习和回忆序列。本文提出了新皮层的每个区域如何学习这个理论所必需的序列。该提议的基础是，皮层列中的所有细胞都具有自下而上的感受野特性，但列中的单个细胞学会在不同序列中代表自下而上的感受野特性的独特发生率。我们讨论的建议，生物的限制，导致它和一些结果建模。
In this paper, we propose a mechanism which the neocortex may use to store sequences of patterns. Storing and recalling sequences are necessary for making predictions, recognizing time-based patterns and generating behaviour. Since these tasks are major functions of the neocortex, the ability to store and recall time-based sequences is probably a key attribute of many, if not all, cortical areas. Previously, we have proposed that the neocortex can be modelled as a hierarchy of memory regions, each of which learns and recalls sequences. This paper proposes how each region of neocortex might learn the sequences necessary for this theory. The basis of the proposal is that all the cells in a cortical column share bottom-up receptive field properties, but individual cells in a column learn to represent unique incidences of the bottom-up receptive field property within different sequences. We discuss the proposal, the biological constraints that led to it and some results modelling it.
