Efficient navigation from one place to another is facilitated by the ability to use spatial boundaries to segment routes into their component parts. Similarly, memory for individual episodes relies on the ability to use shifts in spatiotemporal contexts to segment the ongoing stream of experience. The segmentation of experiences in spatial and episodic domains may therefore share neural underpinnings, manifesting in similar behavioral phenomena and cognitive biases. Here, we review evidence for such shared mechanisms, focusing on the key role of boundaries in spatial and episodic memory. We propose that a fundamental event boundary detection mechanism enables navigation in both the spatial and episodic domains, and serves to form cohesive representations that can be used to predict and guide future behavior.
从一个地方到另一个地方的高效导航是通过使用空间边界将路线分割成其组成部分来实现的。同样，对单个事件的记忆依赖于使用时空背景的转变将正在进行的经验流分割成片段的能力。因此，空间和情景记忆中的经验分割可能具有共同的神经基础，表现出相似的行为现象和认知偏差。在这里，我们回顾了支持这种共享机制的证据，重点关注边界在空间和情景记忆中的关键作用。我们提出，一种基本的事件边界检测机制使在空间和情景领域中的导航成为可能，并形成具有凝聚力的表示，可用于预测和指导未来的行为。
