Many apparent disagreements over the utility of neural manifolds come from a lack of clarity on what the term really encompasses, argues @mattperich.bsky.social

New paper out in #Neuron: A general theory of sequential working memory in prefrontal cortex and RNN/SSMs with their exact neural mechanism. Plus unifying this new mechanism with the alternate mechanism of hippocampal cognitive maps! (1/9)

I am excited to share the last work of my postdoc as a Swartz Fellow at NYU on the dynamic routing of large-scale cognitive networks in the neocortex! 🌐🧠 Here's a quick breakdown: 🧵

preprint: www.biorxiv.org/content/10.1...

1760: Bayes: You should interpret what you see in the light of what you know.
1780: Galvani: Nerves have something to do with Electricity.
1850: Phineas Gauge et al: Different parts of the brain do different things.

Important paper!

Im not sure the Discussion fully delineates its radical implications.

No more...

* Place cells
* Grid cells, splitter cells, border cells
* Mirror neurons
* Reward neurons
* Conflict cells

(continued)

And what does it mean to “truly understand”? Is the something more to understanding than what LLMs do? If you are curious about these questions this blog might help: blog.dileeplearning.com/p/ingredient...

…It boils down to whether we want to recruit people for incremental progress on a path we’re comfortable with, or if we need/want breakthroughs & paradigm shifts. I think we need the latter, & that requires learning from biology first, more than we have, rather than starting & staying in model land.

𝗡𝗼𝗻𝗰𝗼𝗿𝘁𝗶𝗰𝗮𝗹 𝗰𝗼𝗴𝗻𝗶𝘁𝗶𝗼𝗻, subcortex matters!
Happy to share very short piece on thinking of cognition more broadly as solving a broad gamut of behavioral problems, including problems in the "here and now".
