Can AI help understand how the brain learns to see the world? Our latest study, led by @JRaugel from FAIR at @AIatMeta and @ENS_ULM, is now out! 📄 https://t.co/y2Y3GP3bI5 🧵 A thread:

#JNeurosci: Jiang, Cai, Santos-Pata, @kwokszechai et al. found that hippocampal theta oscillation in humans is modulated by repeated experiences, which in turn increases the efficacy of backward-cued memory retrieval of temporal order. @ZJU_China

https://t.co/rRs2Hfw7V1 cool paper! Egocentric value maps for near body environment - possibly complementing allocentric hippocampal maps. Extendible to abstract space I guess? More evidence for knowledge across reference frames!

Nature Neuroscience - Some neurons act like body-proximity sensors. The authors show that these neurons reflect the value of contacting or avoiding objects. Together, these neurons compose a...

This looks pretty interesting! There is a lot of information in eye movements!
Excited to share our paper w/ @Chris_I_Baker in @NatureComms linking active vision & memory! We provide evidence that gaze reinstatement & neural reactivation are deeply related phenomena that jointly reflect the experiences constructed during recall. https://t.co/WK18jVbiUu 1/9

The brain uses orthogonal sub-dimensions in neural space as communication channels. This is a great new paper using Neuropixels from ~6500 neurons on 8 cortical and deep regions in mice. Simplifying the space helps a lot to understand the idea. Here is my toy model and notes:

Also, maybe the time of AI may be way more extended than our time, and therefore lead to conscious behavior which might seem weird to us? @anilkseth - nice piece btw!

Why AI gets stuck in infinite loops — but conscious minds don’t https://t.co/HLkFc7QMNL - Wouldn't be rather simple (although maybe not advisable) to impose states of urgency on the algorithm?

Anil Seth suggests the difference is that living beings are rooted in time and entropy, a grounding that may be essential for consciousness.

A cognitive map for value-guided choice in the ventromedial prefrontal cortex: Cell https://t.co/rjy9J9YdLC - Very cool paper on hexadirectional coding in monkeys and its relation with theta and SWR.
cell.com
Value-based decision-making can be conceptualized as navigation within a cognitive map of choice values. During choice, the ventromedial prefrontal cortex (vmPFC) compositionally builds cognitive...

Comunque @BeppeSala può fare un gesto politico forte: concedere qui e ora una sede al Leoncavallo e spiegare che, pur con idee politiche evidentemente diverse su molti punti, l'antifascismo e la cultura sono terreno, anche fisico, non negoziabile. Tra l'altro lo considero un

very nice @StphTphsn1 !
In a classic study of "mental rotation", Shepard and Metzler (1971) found that the time to compare two 3D cube-made objects was proportional to their angular difference. But *what is going in the brain* during this process? 🔗 Metzler & Shepard (1971): https://t.co/fbtMnbPZR0

The brain’s map of the body is surprisingly stable — even after a limb is lost

Nature - Study challenges the textbook idea that the brain region that processes body sensations reorganizes itself after limb amputation.

In our new paper, we explore how we can build encoding models that are both powerful and understandable. Our model uses an LLM to answer 35 questions about a sentence's content. The answers linearly contribute to our prediction of how the brain will respond to that sentence. 1/6

This is the most heartwarming use of AI I've seen: Teacher makes images of students being their dream profession.
