The Hippocampal Horizon: Constructing and Segmenting Experience for Episodic Memory

Ross, T.W. and Easton, A. (2022) 'The Hippocampal Horizon: Constructing and Segmenting Experience for Episodic Memory.', Neuroscience and biobehavioral reviews., 132 . pp. 181-196.

Abstract

How do we recollect specific events that have occurred during continuous ongoing experience? There is converging evidence from non-human animals that spatially modulated cellular activity of the hippocampal formation supports the construction of ongoing events. On the other hand, recent human oriented event cognition models have outlined that our experience is segmented into discrete units, and that such segmentation can operate on shorter or longer timescales. Here, we describe a unification of how these dynamic physiological mechanisms of the hippocampus relate to ongoing externally and internally driven event segmentation, facilitating the demarcation of specific moments during experience. Our cross-species interdisciplinary approach offers a novel perspective in the way we construct and remember specific events, leading to the generation of many new hypotheses for future research.
