I could not have done this without the sweat and immense effort driven by a whole team of people. @assiachericoni.bsky.social in particular.

I would like to highlight a somewhat tangential finding here: We found clear evidence for clusters in the encoding geometry of natural images and a decision making task (in mice and monkeys). I think this speaks in favor of modular brains in both species.

most people aren’t defining their subspaces. Take the issue of PCA. If experiment cond A pushes a latent to have higher variance than condition B, comparing the two artificially thru alignment artificially inflates “orthogonaliy”. Better to define geometry based on variables and decompose.

A lot of musing about how manifolds replace tuning. But I’d like to argue this is slight misdirection. You don’t get manifolds absent tuning/connectictivity/neuromodulation. Manifolds not in lieu of tuning, but they are independent in so far multiple tunings can render isomorphic manifolds.

I’m happy someone said this. I saw a few packs that had people on it, that don’t even do that research (but I do). But I also suck at self-promoting. Maybe gotta find the bravery to ask for a seat at the proverbial table.

Random opinion: stochastic optimal control theory is underrated in NeuroAI and theoretical neuro. It's one of the most general and useful frameworks out there. Lots of beautiful math and solid proofs. More people should apply it to neuroscience... 🧠🤖

Semi-orthogonal subspaces for value mediate a binding and generalization trade-off - Nature Neuroscience
This study shows that the brain can link action to value through neural population subspaces, balancing reliable binding of action to value and generalization to novel stimuli.

Many researchers in cognitive neuroscience and deep learning seem to assume that inference in the brain is hierarchical.  Our new Nature Reviews Neuroscience paper questions this assumption and proposes the shallow brain hypothesis. #neuroskyence #brain www.nature.com/articles/s41...

Can someone with expertise in navigation neuro (place, grid etc) help me out. What’s the difference between goal distance coding and reward proximity? Is it just you could be close to a rewarding object, but it isn’t necessarily your goal? An exemplar difference/paper would be great.

Can learning occur offline w asyncrhonous inputs? Yes, in systems alignment entire embeddings (e.g., visual and linguistic) are mapped in an unsupervised manner. Systems alignment can support children's word learning. IMO, this is an important form of learning neglected in psych, neuro, and ML.

The problem with effort discounting studies is the reward. It’s not “what would you do for [insert random fruit]”. “It’s what would you do for a Klondike bar?!” Do better psychologists.

This is the right advice. I worked too many weekends in grad school. In hindsight, it was a net loss in mental sanity and life enjoyment. Also, anime recs. are welcomed.
