Very proud to announce our recently published paper led by Gustavo Rodriguez et al. Impaired spatial coding and neuronal hyperactivity in the medial entorhinal cortex of aged APP knock-in mice: www.cell.com/cell-reports...

Impaired spatial coding and neuronal hyperactivity in the medial entorhinal cortex of aged APP knock-in mice

Using the Earth Mover’s Distance and machine learning techniques, Rodriguez et al. show increased instability in spatial representations and impaired spatial information coding in the medial entorhina...

Most neurons seem to be generalists, not specialists. Cortical circuits prioritize diversity over categorical structure. Rarely categorical, highly separable representations along the cortical hierarchy www.nature.com/articles/s41... #neuroscience www.newscientist.com/article/2581...

This recent post by @earlkmiller.bsky.social got my attention. It shows how abstraction could emerge in the primate PFC. The paper is hard, but the main idea can be simplified to low-dims, so I made fun a little animation. A🧵with my toy model and notes: #neuroskyence #compneuro #NeuroAI

Scientists have long debated whether neurons are jacks of all trades or tend to specialize in one thing. Now @stefanofusi.bsky.social, @lorenzoposani.com & Liam Paninski present new evidence in @nature.com shedding light on how the brain performs complex tasks. tinyurl.com/yj3ew8en

From a great collaboration with @lorenzoposani.com, @shuqiw.bsky.social, Samuel Muscinelli, Liam Paninski, now in Nature: www.nature.com/articles/s41...

Out today on @nature.com! Connecting neural specialization, population geometry, and their functional implications across the cortical hierarchy. So grateful for this beautiful and fun collaboration with @shuqiw.bsky.social, S Muscinelli, L Paninski, and @stefanofusi.bsky.social!

Our paper "Rarely categorical, highly separable representations along the cortical hierarchy" is now out in Nature! www.nature.com/articles/s41... In this paper, we studied whether the brain is well-organized and interpretable, both globally and locally. (See thread below.)

Every summer I repost this article on how to spot drowning. Please read it and pass on. In the last few years I’ve had SIX messages from people who saved a kid’s life after clicking on the link from my feed. slate.com/technology/2...

Drowning Doesn’t Look Like Drowning

Drowning is not the violent, splashing call for help that most people expect.

In my utopian vision of the future, instead of offloading all the pointless, annoying work tasks (like reports that none one will read and needlessly opaque forms) to robots, we restructure work and society so that the pointless tasks don't happen at all.

Somebody should invent a socioeconomic system which is good at allocating resources

Reminder: All it would take to end the murder of American citizens by an untrained government goon squad is 16 Republicans in Congress voting with Dems to defund ICE (or 23 to impeach and remove Trump — 3 in House & 20 in Senate). That’s it. 23 Americans can vote for the public and end all of this.

I just thought everyone should see this

Europe's MSCA postdoctoral fellowships are now attracting many researchers who would have gone to the US. So the payline has dropped below 10% (~1,600 fellowships to 17k applicants). Super tough situation. One more reason to double the next Horizon budget, as proposed by the EU Commission.

Applications for MCSA are up 64%! 50% now come from outside the EU. Trump effect? The European Research market just got a hell of a lot more crowded. EU should turn on the tap marie-sklodowska-curie-actions.ec.europa.eu/news/msca-po...

"The myth of meritocracy in science collapses under the financial sacrifices expected at every career stage. From unpaid internships and self-funded conferences to underpaid positions, these hidden costs disproportionately exclude those without generational wealth, compounded by race and gender."
