New paper that merits a read (Im totally unbiased...not). Simple, straightforward, impactful message. Prediction a la LLM is nice. Constituent-constrained prediction is nicer. @jiajiezou.bsky.social and Nai Ding show brain, behavioral, MEG, ECoG data.

How do RNNs learn abstract rules from sequences, independent of specific stimuli?

"From sequences to schemas: low-rank recurrent dynamics underlie abstract relational representations"

With some trepidation, I'm putting this out into the world:
gershmanlab.com/textbook.html
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.

🎉 Excited to share our publication in PNAS! 🎉
What happens when our stream of consciousness turns towards the body? Our fMRI study of 536 individuals finds that 'body-wandering' is associated with patterns of brain connectivity, physiology, affect, and mental health:

This is really cool!
Attention fluctuates over time and across contexts—how is this reflected in the brain?🧠 Fitting a dynamical systems model to fMRI data, we show that the geometry of neural dynamics along the attractor landscape reflects changes in attention. Out in @natcomms.nature.com

Thank you to the conference organizers @cogneuronews.bsky.social for the wonderful CNS2026 experience!
We were excited that @catalinayang.bsky.social and @matthewdougherty.bsky.social got to share their amazing work! Thank you to everyone who attended the sessions!

Scientists are always doing what's interesting to them, but I think that's the wrong approach. We should be going after all the stuff that bores us. Because it's actually not boring at all once you get into it, and it's precisely the things we think are going to be boring that open our minds.
🚨 New lab paper!🚨
A dream study of mine for nearly 20 yrs not possible until now thanks to NIH 🧠 funding & 1st-author lead @seeber.bsky.social
We tracked hippocampal activity as people walked memory-guided paths & imagined them again. Did brain patterns reappear?🧵👇

RIP redundancy reduction?
Beautiful work by Liu & colleagues showing that neural redundancy increases with learning, as predicted by a Bayesian model:

How does the brain generalize past experiences without confusing memories? 🧠
Our lab's newest preprint reveals a fundamental division of labor between the cortex and cerebellum that solves this problem. (Check out the cortex-cerebellum video below! 👇) 🧵

Delighted to share this paper led by @hannahmcdermott.bsky.social . We examined dynamics of prediction effects (sharpening vs dampening) and found they’re completely different across time scales!
Out now in #JNeurosci! We used direct recordings and stimulation in human pulvinar to probe its causal role during naming from pictures, and spoken and written descriptions. We found naming-selective responses and stim-induced pure anomia.

Super happy to share my very first first-author paper out in
@sfnjournals.bsky.social! We show content-specific predictions are represented in an alpha rhythm. It’s been a beautiful, inspiring, yet challenging journey.
Huge thanks to everyone, especially @peterkok.bsky.social @jhaarsma.bsky.social
Thanks buddy! Indefatigable! What a word! It’s been such a joy to share a journey in academia with you at multiple stops along the way. Let’s keep on persisting tirelessly!

As promised: a detailed figure-by-figure thread on our @pnas.org paper:
doi.org/10.1073/pnas...
We use signal correlations and noise correlations in chronic imaging data to show that representational drift is shaped by a balance between Hebbian and stochastic changes.
Let’s dive in 👇

Whether the system can be flexibly redirected to prioritize specific locations has been unclear. Using large-scale #Neuropixels recordings in freely behaving rats, we find that both sweeps – and the internal direction signals driving them – are dynamically modulated moment by moment. (4/6)

Theta/alpha oscillations can aid cortical information transfer in-silico - a mechanism in line with MEG network state transitions in several working memory tasks

How do we balance external attention to the outside world and internal attention to our thoughts & memories?
We review evidence that external and internal attention can compete, unfold concurrently, or cooperate!
Loved working on this with @samversc.bsky.social & @tobiasegner.bsky.social!
lol thanks buddy!!
Thanks Mariam!! I really appreciate the kind words :) it’s been quite a journey getting to the finish line! Excited for what is to come!
I am excited to share my first paper, showing that episodic memory formation is theta rhythmic, is now published in Nature Human Behavior! Check it out here: rdcu.be/e6pzS. Thanks to my PI, Katherine Duncan, and to my collaborators for their support on this journey! Stay tuned for iEEG follow up 🧠
