Triple-N is fantastic—a dataset that was collected with a lot of thought and care. Neuropixel recordings in 5 monkeys viewing 1000 NSD images! Some friends and I did a short write up on large-scale community data resources like this, check it out: www.nature.com/articles/s41...

I just submitted a comment on the proposed new OMB rule, which is very dangerous fo rUS science. I urge you to consider doing the same. You can do so very easily at this web page: fight2win.standupforscience.net/campaign/164... A short comment is fine but write in your own words. More info follows..

Really cool work, excited to take a closer look! side note: so glad that people are finding value in our EMFL data!

🚨 New Preprint! 🧠 We gave an AI model one simple rule: rearrange your neurons so that nearby ones respond alike. We never told it what a face, a voice, or a sentence was. It grew brain-like maps for all three anyway. 🧵👇 🌐 Website: topo-omni.epfl.ch

What does it mean to understand language? We argue that the brain’s core language system is limited, and that *deeply* understanding language requires EXPORTING info to other brain regions. w/ @neuranna.bsky.social @evfedorenko.bsky.social @nancykanwisher.bsky.social arxiv.org/abs/2511.19757 1/n🧵👇

What does it mean to understand language?
Language understanding entails not just extracting the surface-level meaning of the linguistic input, but constructing rich mental models of the situation it describes. Here we propose that because pr...

Whelp. See you later 1.8 Million in NSF research funds -- all designed to better understand learning mechanisms in early childhood so we can develop effective early childhood educational interventions. Proud of Harvard for standing up to fascism, though. We will persist.

A 19-year-old university student from Gaza I know, who is brilliant and charming and usually upbeat, just wrote back: "we are not OK. The bombing is continuous and non-stop. Please pray for us. Happy Eid to you."

I’m hiring a full-time lab tech for two years starting May/June. Strong coding skills required, ML a plus. Our research on the human brain uses fMRI, ANNs, intracranial recording, and behavior. A great stepping stone to grad school. Apply here: careers.peopleclick.com/careerscp/cl... ......
