New preprint by @sarahehenderson.bsky.social. The *real* blood, sweat, and tears of her PhD - trying to develop an intervention to improve episodic memory in older adults under naturalistic conditions.

"Event tagging" is simple, but holds real promise. #PsychSciSky #memory

Our new paper in @sfnjournals.bsky.social shows different neural systems for integrating views into places--PPA integrates views *of* a location (e.g., views of a landmark), while RSC integrates views *from* a location (e.g., views of a panorama). Work by the bluesky-less Linfeng Tony Han.
#JNeurosci: Using fMRI, Han and Epstein explored how people integrate different kinds of views to form mental maps of places, revealing two sets of brain regions involved in integrating views of landmarks into existing mental maps of a virtual city.

With some trepidation, I'm putting this out into the world:

It's a textbook called Computational Foundations of Cognitive Neuroscience, which I wrote for my class.

My hope is that this will be a living document, continuously improved as I get feedback.

A neural state space for episodic memories
Episodic memories are highly dynamic and change in nonlinear ways over time. This dynamism is not captured by existing systems consolidation theories …

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

📣 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.
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.
