@pixeltracker I've had that happen before when clicking publishers' doi links, maybe the doi organization takes a little longer to push changes than large journals like Cell.
This paper is really cool though. A nonlinear model of how the cortex and hippocampus continuously interact to co-create and reinstate memories helps flesh out some of my understanding on how perception-memory-cognition is a dynamic interdependent network.
I wish the state space idea was more detailed as a model though, like mathematically. That could be done in "further research" I'm sure. Also I want to go through @adredish 's 1999 book "Beyond the Cognitive Map" http://redishlab.neuroscience.umn.edu/Papers/1999%20ByCM.pdf again with this paper by AJ Horner, because in it he lays out theoretical frameworks for hippocampal place cells like switching between multiple cognitive maps and attractor networks, then mentions near the end how episodic memory could use similar mechanisms
@axoaxonic @adredish Fully agree 👍 Horner's framework really begs for a formal dynamical model: defining trajectories, #attractors, and #manifolds within that 3D space. Something that could turn his conceptual #StateSpace into a genuine #computational theory of #memory dynamics.
I didn’t know Redish's book ("Beyond the Cognitive Map") before your comment! Sounds highly relevant and I’ll definitely put it on my reading list 👌
🧠 New paper by Aidan J. Horner (2025, Trends in Cognitive Sciences) introduces a 3D neural #StateSpace for #episodic memories. It replaces linear #SystemsConsolidation models with a dynamic framework where #hippocampal, #neocortical, and episodic specificity dimensions evolve independently and non-linearly, allowing memories to shift, reverse, or re-engage hippocampal circuits.

University of New Mexico #scientist is revealing what might be one of the most overlooked causes of #dementia — damage in the #brain tiny #bloodvessels. Dr. Elaine Bearer has created a new way to classify these changes, showing that many people diagnosed with #Alzheimers also suffer from #vascular damage that quietly destroys #brain tissue. Even more surprising, she’s finding #microplastics inside the brain that appear linked to #inflammation & #memory loss. https://www.sciencedaily.com/releases/2025/10/251005085637.htm #healthcare

Does human episodic memory 🧠 depend on context-invariant or conjunctive coding of single neurons in the human hippocampus?
A recent TiCS (https://www.cell.com/trends/cognitive-sciences/fulltext/S1364-6613(25)00031-2) paper stimulated a very interesting debate about the nature of hippocampal coding in human episodic memory that i found very insightful.
The discussion centers around context-invariant coding of concept neurons (CN) vs. conjunctive coding of episode-specific neurons (ESN) in the hippocampus, both following different lines of thinking about the HCs involvement in episodic memory.
