The brain represents the world around us as a series of neural states - stable patterns of activity that change as we move from one event to the next.

New paper by @selmalugtmeijer.bsky.social showing that neural states get longer as people age. #PsychSciSky

Temporal dedifferentiation of neural states with age during naturalistic viewing - Communications Biology

Movie fMRI data reveals age-related lengthening of neural states in visual and prefrontal regions, reflecting reduced temporal differentiation while preserved alignment with perceived events suggests stable coarse event segmentation.

How might stories shed light on brain function? Check out this opinion piece by @alexbarnett.bsky.social and I about the DMN and "situation models" -- our understanding of the current "state of affairs" in a story (or even experience).

On the left: an illustration from Brooke's 1904 rendition of Goldilocks and the Three Bears, where Little bear discovers their favourite chair is broken 😲. On the right, a sketch of what a corresponding "situation model" might contain.

How does the brain🧠 make causal inferences and use memories to understand narratives🎬?

We built an RNN🤖 with key-value episodic memory that learns causal relationships between events and retrieves memories like humans do!

A neural network with episodic memory learns causal relationships between narrative events

Humans reflect on past memories to make sense of an ongoing event. Past work has shown that people retrieve causally related past events during comprehension, but the exact process by which this causa...

1/ 🚨 Preprint alert!
How does the brain make sense of continuous experience?
We find that continuous experiences can be compressed using a subset of key moments that dominate comprehension and recall.

How do the brain’s event representations change as we gain familiarity with an experience?

Brain regions’ representations can become coarser or finer as event familiarity increases. Fine-tuning predicts memory recall.

Is the hippocampus best understood in term of discrete subfields or functional gradients?

Functional gradients are recapitulated within each hippocampal subfield, supporting a role for both discrete & continuously changing computations.

Neat work by Bouffard, @barense.bsky.social, & Moscovitch!
