🧠🚨 How does the hippocampus transform the visual similarity space to resolve memory interference?

In this new preprint, we found that the hippocampus sequentially inverts the behaviorally relevant dimensions of similarity 🧵

Hippocampal transformations occur along dimensions of memory interference

The role of the hippocampus in resolving memory interference has been greatly elucidated by considering the relationship between the similarity of visual stimuli (input) and corresponding similarity o...

Memory might depend on when you look, not just what you see

Happy to share a new preprint from my postdoctoral work with Jed Meltzer, @drjenryan.bsky.social, and @rosannaolsen.bsky.social

Paper: doi.org/10.1101/2025...

Phase-locking saccades to posterior alpha oscillations improves the neural representation of visual objects during memory formation

Visual memory formation begins with the intake and neural processing of discrete samples provided by gaze fixations and saccades. Past research has highlighted a functional relationship between the ti...

Why do we remember emotional events so vividly? Our new paper @nathumbehav.nature.com suggests that emotional arousal enhances memory by strengthening integration across large-scale brain networks! Led by the amazing @jadynpark.bsky.social & @ycleong.bsky.social! doi.org/10.1038/s415...

Out now in @nathumbehav.nature.com! We applied graph theoretic analyses to fMRI data of participants watching movies/listening to stories. Integration across large-scale functional networks mediates arousal-dependent enhancement of narrative memories. Open access link: rdcu.be/eKKAw

In this article, @jadynpark.bsky.social et al find that emotionally arousing moments during a narrative are associated with heightened integration across functional brain networks, which in turn predict how well those moments are then remembered.

This is one of those papers that just deserves a post every now and then. Half a century old, with a message still relevant today: Cognition won't be understood one variable at the time.

Creative experiences and brain clocks - Nature Communications

Creative experiences such as dance, music, drawing, and strategy video games might preserve brain health. The authors show that regular practice or short training in these activities is linked to brains that look younger and work more efficiently.

Sometimes I think about how from 1935-1975ish, Bell Labs produced an insane amount of revolutionary science and technology, including 11 Nobel Prizes, the transistor, UNIX, C, the laser, the solar cell, information theory, etc. The secret? Provide scientists with ample, steady, no-strings funding.

Imagine an apple 🍎. Is your mental image more like a picture or more like a thought? In a new preprint led by Morgan McCarty—our lab's wonderful RA—we develop a new approach to this old cognitive science question and find that LLMs excel at tasks thought to be solvable only via visual imagery. 🧵

When a typo in your Google search leads to new and exciting philosophical positions

AI Overview: "Dental realism"refers to the philosophical debate about whether teeth exist independently of human perception, a concept rooted in metaphysical realism. While realism asserts an objective reality for teeth, idealist philosophies contend that teeth's existence is tied to our consciousness and perception. Philosophers use this idea, for example, to discuss the ethics of tooth extraction, examining whether a procedure impacts a real entity or merely a subjective experience.

Data only shows associations. Turning those into claims about mechanism or causation? That requires a Rosetta Stone of prior knowledge + theory. Resting-state fMRI is purely observational; correlation is its currency. From this, plenty of "theoretical toys" about brain function can be built...
