‘Seek Funding’ Step Added To Scientific Method

📰 I really enjoyed writing this article with @thetransmitter.bsky.social! In it, I summarize parts of our recent perspective article on neural manifolds (www.nature.com/articles/s41...), with a focus on highlighting just a few cool insights into the brain we've already seen at the population level.

Brain Surfaces of 70 primate species

To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised!

Explosive neural networks via higher-order interactions in curved statistical manifolds - Nature Communications Higher-order interactions shape complex neural dynamics but are hard to model. Here, authors use a generalization of the maximum entropy principle to introduce a family of curved neural networks, reve...

Our paper just out in Nature Communications!
www.nature.com/articles/s41...

We introduce curved neural networks naturally introducing high-order interactions showing:
• explosive phase transitions
• enhanced memory retrieval via self-annealing
• increased memory capacity through geometric curvature

Wake up, babe. A new mapping stimulus just dropped.

Introducing our new favorite stimulus. A few minutes are enough to map the visual preferences of thousands of neurons.

Awesome work!! Can BRISC detect both sources and targets between all the infected neurons? Or is it one-way only?

Barcoded Rabies In Situ Connectomics for high-throughput reconstruction of neural circuits Sequencing of oligonucleotide barcodes holds promise as a high-throughput approach for reconstructing synaptic connectivity at scale. Rabies viruses can act as a vehicle for barcode transmission, than...

1/ Mapping synaptic connectivity between individual neurons is extremely laborious. We developed BRISC, a new method that makes it possible to map inputs onto 100s of neurons in the same animal in a matter of weeks! Led by Alex Becalick and @antblot.bsky.social. 🧵

Universities and Researchers Save The World All the Time

In July 2025 Superman once again saved the world on the big screen. Luckily for us, humanity's ranks are filled with real superheroes who are saving the world every day (to less cinematic fanfare.)

Poster submissions are open for a few more days, don't miss the chance!

Also feel free to send me a DM if you need a member support to become part of the Bernstein Network 😄

Undecided whether to attend the #BernsteinConference2025 ?

@ackurth.bsky.social and myself put together a stellar lineup for a satellite workshop on the effects of top-down signals on neuronal dynamics! 🧠✨📣

Sure

Oh man, there were too many great talks at the same time!! So sad I could not hear yours 🫠

Sure!

@bernsteinneuro.bsky.social is this skeet enough?

🙋‍♂️

Brain networks from many animals have nonrandom structure. Including high clustering, short path lengths, heavy tailed weight distributions, and heavy-tailed degree distributions.

Are you at the @cnsorg.bsky.social conference?

Do you like networks? Brain-like networks? Pretty and structure rich networks? 🙇‍♂️🧠🕸

Come to my Poster 204 this afternoon (or anytime today)!!

The poster is right next to the coffee! ☕️ 😉

Higher dopamine D1 receptor expression in prefrontal parvalbumin neurons underlies higher distractibility in marmosets versus macaques - Communications Biology Integrative anatomical, molecular, behavioral, and modeling evidence suggests that higher dopamine D1 receptor expression in prefrontal cortical parvalbumin neurons in marmosets likely contributes to ...

Textbook neuroscience teaches that anatomy dictates function. But which aspects of anatomy determine differences in function between species? We think neuroscience is now well-placed to tackle this question. Here is our attempt at one piece of the puzzle: www.nature.com/articles/s42...

Characterizing Neural Manifolds' Properties and Curvatures using Normalizing Flows Neuronal activity is found to lie on low-dimensional manifolds embedded within the high-dimensional neuron space. Variants of principal component analysis are frequently employed to assess these manif...

How about some science to cleanse the timeline?

Some nice physics to infer the properties of neural manifolds from brain data 💫🧠

Cause the brain is complicated and unforgiving. Everything is happening all at once, there are no shortcuts, the theories must explain it all or fail. So they often fail 🤷‍♂️

If they do a 10x version and it turns out the network structure is kind of the same, that would be huge!

Scale invariance? That's the stuff physicist dreams are made of

Maybe the issue is that we no longer have a narrow view on things determined exclusively by a small group of white men.

It is hard to "disrupt" the consensus nowadays, because it is broader and more inclusive, which is a VERY good thing.

I wonder how many misleading ideas are in circulation 🫠

I've been writing a textbook on computational cognitive neuroscience, which has prompted me to assess the evidence supporting various theoretical ideas. It's striking to me how some ideas have an extraordinary shelf life despite weak evidence.

I got fooled by AI-for-science hype—here's what it taught me I used AI in my plasma physics research and it didn’t go the way I expected.
