We develop a geometric theory of how neural populations support generalization across many tasks.

Interesting convergence:

The trick that made predictive self-supervised vision models work seems to be what the brain was doing all along

w/ @predictivebrain.bsky.social: visual cortex is most sensitive to high-level prediction errors -- even in V1

Really thrilled that this paper led by @neurozz.bsky.social is now published in its final version in @elife.bsky.social!!

This is a memory-focused (as opposed to RL-focused) account of the detailed characteristics of forward and backward awake and sleep replay!

“Uruguay did what most nations still call impossible: it built a power grid that runs almost entirely on renewables—at half the cost of fossil fuels. The physicist who led that transformation says the same playbook could work anywhere—if governments have the courage to change the rules.”

With some trepidation, I'm putting this out into the world:

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.

This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

There's been a cluster of recent work on these sort of flow based or trajectory based world models, including nova flow and amplify (amplify a past episode of ours). These are super exciting because they reduce requirements for really accurate action labels imo

Using brain lesions and DNN models, this article suggests that human visual perception is modulated by language.
Combined evidence from artificial neural networks and human brain-lesion models reveals that language modulates vision in human perception - Nature Human Behaviour
Vision–language deep neural network models better explain human visual cortex activity than vision-only models. Damaging brain connections between visual and language areas reverses this pattern, suggesting that human visual perception is modulated by language.

Dimensionality reduction may be the wrong approach to understanding neural representations. Our new paper shows that across human visual cortex, dimensionality is unbounded and scales with dataset size—we show this across nearly four orders of magnitude. journals.plos.org/ploscompbiol...

I am very excited and grateful to have been awarded a Consolidator grant by @erc.europa.eu. We will use it to investigate the role of memory in perception, focused on the hippocampus. Thank you to all the colleagues in my team and the department for their support in making this possible!
