So, apparently big tech firms are telling employees to get back to the US before midnight eastern time tonight, or else avoid returning entirely until there is more clarity. ¯\_(ツ)_/¯

🎉 "High-dimensional neuronal activity from low-dimensional latent dynamics: a solvable model" will be presented as an oral at #NeurIPS2025 🎉 Feeling very grateful that reviewers and chairs appreciated concise mathematical explanations, in this age of big models. www.biorxiv.org/content/10.1... 1/2

Join the 2025 UCL Neuropixels course (free and online!), 22-24th of October: Day 1 and 2: Get started with the basics and the latest updates on hardware & software. Day 3: Focus on how to analyse the many neurons you recorded. More info and to register: www.ucl.ac.uk/neuropixels/...

For a reasonable person, it is hard to imagine how racist are the views of Elon Musk. In his view immigrants cause "rape and murder and the destruction of the country and dissolution of the entire way of life". His words are disgusting. www.standard.co.uk/news/uk/elon...

Exciting opportunity here - if you have a dataset and want IBL staff to run pipelines, develop visualizations or websites, work on QC, etc - or if you want to work on the IBL dataset in a way that needs staff support - then this is for you! Check it out.

Thrilled to share that our work is now published in Science! ✨ We found a preference for visual objects in the mouse spatial navigation system where they dynamically refine head-direction coding. In short, objects boost our inner compass! 🧭 www.science.org/doi/10.1126/... 🧵1/

The first complete activity map of decision-making in the animal brain has been unveiled by a large international collaboration of neuroscientists involving @uclqsion.bsky.social and @ucleye.bsky.social researchers. www.ucl.ac.uk/news/2025/se... @kenneth-harris.bsky.social @carandinilab.net

The first complete activity map of a mammalian brain has revealed unprecedented insights into how decisions are made – and may even hint at the roots of intuition.

The ‪@intlbrainlab.bsky.social published 2 papers today on their work to create a map of neural activity across the entire mouse brain. Learn more about the lab: https://www.simonsfoundation.org/2025/02/20/how-do-our-brains-make-decisions-the-international-brain-laboratory-is-closing-in-on-answers/

Two flagship papers from the International Brain Laboratory, now out in ‪@Nature.com‬: 🧠 Brain-wide map of neural activity during complex behaviour: doi.org/10.1038/s41586-025-09235-0 🧠 Brain-wide representations of prior information in mouse decision-making: doi.org/10.1038/s41586-025-09226-1 +

A complete brain-wide activity map at single-cell resolution has been revealed for the first time. Researchers recorded from 650,000+ neurons across 279 brain areas to track decision-making in mice. Read the story: 🔗 www.sainsburywellcome.org/web/research...

Today, our article "The entities enabling scientific fraud at scale are large, resilient, and growing rapidly" is finally published in PNAS. I hope that it proves to be a wake-up-call for the whole scientific community. reeserichardson.blog/2025/08/04/a...

I have some BIG NEWS to share today! Today I begin my next adventure as Chief Editor of Nature Biomedical Engineering!! (a thread) @natmethods.nature.com @natbiomedeng.nature.com @natureportfolio.nature.com

Using the @intlbrainlab.bsky.social BWM dataset, which comprises electrophysiological recordings of 60 k neurons covering one mouse brain hemisphere, we find all brain regions contain most neural response types, i.e. function is widely distributed: www.biorxiv.org/content/10.1...

It looks like all NSF/NIH grants to UCLA (including mine and all fundamental neuroscience grants) have been suspended. www.science.org/content/arti...

Some neurons respond more strongly to visual stimuli than others. But the rest of the brain doesn’t prioritize signals from those neurons, according to a new study. Read more in this month’s Null and Noteworthy. By @ldattaro.bsky.social #neuroskyence www.thetransmitter.org/null-and-not...

so proud of this team!!! they're changing the way grants are sought, written, and funded. and such critical work - greenhouse gases this cycle, focused on methane. they funded us (+ Michael Konopka, USNA) to study methane monooxygenase (pMMO), potentially the key to remediating methane pollution.

This is unfortunate: www.nytimes.com/2025/07/28/u... I wrote to the president of Harvard. I hope other faculty will speak their conscience, even if it means more struggle ahead.

Remote activation of place codes by gaze in a highly visual animal www.nature.com/articles/s41... - very cool study with chickadees!

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

It is with great sadness that we announce the passing of beloved @ucleye.bsky.social colleague Prof Pete Coffey. A pioneer in stem cell therapy, his research has helped restore sight to people with macular degeneration. His legacy will continue to transform lives.

The Commission is pushing for a massive increase in funding for Horizon Europe 2028-2034. If I understand correctly, Pillar I, which includes @erc.europa.eu and Marie Sklodowska Curie fellowships, would go from the current €25 billion to €44 billion. Let's hope it happens!

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. 🧵 www.biorxiv.org/content/10.1...

US students are increasingly applying to UK unis. They are at 6%, and rapidly growing. Makes sense: it costs less, lasts 3 years (typically), does not infantilize (re drinks). And no kidnapping by masked thugs (yet). However, courses focus on a single discipline. Link (paywall): on.ft.com/4nYb1Ry

Abundant aid is sitting on the border, if IL would let it in. After complete blockade for months they now are allowing in only a trickle. That combination is creating the current, rapidly worsening situation. How many people must die of starvation before the world will pressure IL to open the gates?

Welcome to Bluesky @kenneth-harris.bsky.social !

A new study led by @timothysit.bsky.social reveals that different layers of mouse V1 integrate visual and non-visual signals differently. Activity is dominated by vision (or spontaneous fluctuations) in L2/3 and by movement in L5. This leads to different geometries. www.biorxiv.org/content/10.1...
