🚨 new work from the lab on how eye movements 👀 versus orofacial movements influence 🐭 visual cortex activity 🧠 #neuroscience #behavior #neuroAI

Planyourscience.com now applauds the good changes you make - and pushes back on the less good one.

@sebastianseung.bsky.social Did you follow through on your plan to visit Epstein island?

Hey @eboyden3.bsky.social care to explain?

Excited to share “Orofacial behaviors, not eye movements, govern neural activity in mouse visual cortex” www.biorxiv.org/content/10.6... Summary below...

I have so many issues with this podcast with @earlkmiller.bsky.social . I think that this podcast nicely shows why I have trouble with such approaches. Lets go through some of the claims.

Even colleagues who should know better are claiming that we are halting animal research. No, we're not. Now this NYT opinion piece appears (gift link) www.nytimes.com/2025/10/08/o... You can't just move everything to cell culture, organoids, and computers. Even this NYT piece admits that. 1/3

Is visual cortex more like chatGPT or a masked autoencoder? Come to my BCCN seminar tomorrow at 10am ET on zoom (or read the paper) to find out! #neuroscience Zoom: urldefense.com/v3/__https:/... Paper: www.biorxiv.org/content/10.1...

New work from the lab, mismatch responses consistent with spatial but not temporal predictive coding theory.

Does predictive coding work in SPACE or in TIME? Most neuroscientists assume TIME, i.e. neurons predict their future sensory inputs. We show that in visual cortex predictive coding actually works across SPACE, just like the original Rao+Ballard theory #neuroscience www.biorxiv.org/cgi/content/...

💻A new class of simplified ‘minimodels’ developed by Fengtong Du, Miguel Angel Núñez-Ochoa, @marius10p.bsky.social & @computingnature.bsky.social can predict the visual responses of individual neurons in the primary visual cortex, helping shed light on how we see.👀 ➡️ www.janelia.org/news/new-com...

Your brain learns for you even when you're not actively learning. Maybe. (in mice).

Our paper on NHP neuropixels is finally out in Nat Neuro! These probes have already been transformative and will usher in a new era of primate neuroscience. I am extremely proud to have played a very small role in this project. I can't wait to see what our community discovers. tinyurl.com/54u3hrj8

AI doesn't have to be shit

🚶Aimlessly wandering around a city or exploring the new mall may seem unproductive, but new research led by @zh0ng0.bsky.social @marius10p.bsky.social @computingnature.bsky.social suggests it could play an important role in how our brains learn.‬‬ 🧠 🔗 www.janelia.org/news/zoning-...

Everyone in the lab is raving about Cellpose-SAM. Segmenting the previously unsegmentable across a range of different cell types and markers.

Wouldn't it be great if we could not only image large connectomic volumes but also completely reconstruct them? And if a whole mouse brain project didn't cost billions? With the PATHFINDER preprint (www.biorxiv.org/content/10.1...), we preview a future where it doesn't have to.

Subspace communication to me is essentially correlation on crack.

Here are some things that neuroscientists don't like to call "correlation": 1990s: "reverse correlation" 2000s: "granger causality" 2010s: "functional connectivity" 2020s: "subspace communication"

Be successful, run a big lab. Have many (12) grad students. Play the numbers game. Some are bound to get a paper, the others we dont talk about, they're dead to us. post-hoc test, survivors used git
