This talk is part of the Department of Psychology (Durham University) seminar series.

Cognitive models addressing human long-term event memory have posited that our experience is segmented into discrete units (e.g., Radvansky & Zacks, 2014). We have recently argued on the basis of evolutionarily conserved neurobiological mechanisms that mammals (and likely other animals) similarly segment their experience (Ross & Easton, 2022). Here, I will present behavioural evidence that rats can use different mnemonic strategies to remember events, which I will interpret in relation to event segmentation. I will also present human behavioural evidence that simple spatial context can modulate event segmentation and memory, and that such spatial context has been seen to modulate single cell activity in the rat hippocampal formation (HF). Finally, I will discuss preliminary electrophysiology data in mice, which aims to investigate how the activity of single cells in the HF can support the construction and segmentation of experience for subsequent long-term memory in a context-dependent manner. In summary, this work aims to better bridge the human and non-human animal literature to enhance our understanding of event segmentation, memory and learning.
