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.

📣 Helpful thread about a great paper alert!

Okay - I am biased, but I am super proud of this paper and @dkvarga.bsky.social has done a truly awesome job of running this project (3 separate fMRI studies!). Thanks also to our amazing colleagues for their support.

Dominika Varga @dkvarga.bsky.social · Sep 4

So happy to share our paper on the role of the hippocampus as a mismatch detector:
doi.org/10.1073/pnas...

We show that the hippocampus detects mismatches between ongoing experiences and episodic memories but not generalised schematic knowledge.

See 🧵for how we got here:

We make predictions based on general knowledge and/or specific memories. Different brain areas are active when these distinct predictions are violated – and hippocampus selectively responds to prediction errors based on episodic memory.

New preprint! How do we integrate new information into prior knowledge? We find that existing knowledge enables rapid new learning but that interleaved replay during sleep promotes integration of new and old information. Modeling suggests a sleep context suppression mechanism.
