How do we update our predictions when our environment changes?

The hippocampus rapidly integrates previously distinct sequences to support updated predictions.

The Hippocampus Rapidly Integrates Sequence Representations During Novel Multistep Predictions

Memories for temporally extended sequences can be used adaptively to predict future events on multiple timescales, a function that relies on the hippocampus. For such predictions to be useful, they sh...

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.

Fresh results now in bioRxiv! 🎉 We know about the function of NREM sleep for overnight memory consolidation. But what about REM sleep? We found that in aging, slow delta waves can intrude phasic REM periods, and this, is associated with worse overnight consolidation 🧠 (1/5) doi.org/10.1101/2025...

New paper with @mujianing.bsky.social & @prestonlab.bsky.social! We propose a simple model for human memory of narratives: we uniformly sample incoming information at a constant rate. This explains behavioral data much better than variable-rate sampling triggered by event segmentation or surprisal.

Are the brain's representational formats predetermined by its intrinsic architecture, or are they efficiently tuned to the statistical structure of the visual world? In our new study, we test these possibilities.

So proud of this fantastic and inspiring work, led by @jazzmaniatico.bsky.social.

Pablo Marcos-Manchón @jazzmaniatico.bsky.social · Jul 25

🧠🚨 How does the brain represent what we see? Is visual input transformed to form these representations in similar ways across people and even AI models like DNNs?

We explore these questions using fMRI and large-scale representational alignment analyses.

However, patients with damage to subcallosal vmPFC fail to show a well-known Intention Superiority Effect, which indexes an automatic privileged access to cognitive processing of environmental cues that are associated with an intention to perform a future action.

Asaf Gilboa @agilboa.bsky.social · Jul 17

Patients with vmPFC damage are relatively intact on prospective memory tasks that require conscious monitoring and detection of cues that should trigger a future action. They are able to disengage from an ongoing task to perform the prospective intention.

As mentioned above, perplexity is much better. It makes errors too, but it provides the specific references so you can directly check the answers and follow up to correct those.
