- Heating homes with the world’s largest particle accelerator Now operational, a new heat exchange system is reusing hot water from part of the Large Hadron Collider’s cooling system to heat homes and businesses in the local area. Read more: home.cern/news/news/ce...
- Interested in a fellowship in London? Come and join me in my department. The department is EE but research topics can be very wide: happy to host people with any overlapping interests in NeuroAI/SNNs/etc. More info on available fellowships and timelines here: www.imperial.ac.uk/electrical-e...
- Happy to share our preprint with @neworderofjamie.bsky.social , @danakarca.bsky.social and @drtnowotny.bsky.social ! We’ve been working on a neuron position learning algorithm by coupling space and time! See manuscript below 👇
- Come do your PhD with me and @ktsetsos.bsky.social ! It's such an exciting time for cognitive and computational neuroscience at @tcddublin.bsky.social . And in this PhD you get to do both!
- 🎓Fully-funded PhD studentship in Computational Cognitive Neuroscience!!! Join @seanfw.bsky.social and myself at @tcddublin.bsky.social for a PhD at the intersection of cutting-edge cognitive neuroscience (OPM-MEG) and neuro-AI. 🗓 Deadline: 5 Feb 2026 #neurojobs #neuroscience #compneuro
- This Thursday at 3PM (UTC), we'll host @barabasi.bsky.social at the Making Connections seminar series. I'm sure it'll be a very stimulating and inspiring talk, so if you'd like to join, register via the link below: sites.google.com/view/makingc...

- It's a small contribution, but I finally bit the bullet and removed all references to Twitter/X from my website. Where previously I had embedded tweeprints on my website, I've now pasted all the content into something without links/mentions of twitter, e.g. here neural-reckoning.org/pub_multimod...
- @kordinglab.bsky.social and I ran a summer school last year to help young profs (<5 yrs) in systems/comp neuro thrive. compneurosci.com/Neuro4Pros/i... It was great! Now we want to know if you'd be interested in participating if we did this again this year? Let us know!
- How does the structure of a neural circuit shape its function? @neuralreckoning.bsky.social & I explore this in our new preprint: doi.org/10.1101/2025... 🤖🧠🧪 🧵1/9
- All hail the T-wings fleet of pRNNs
- For the first Learning Club @cmc-lab.bsky.social in 2026, @marcusghosh.bsky.social on Jan 15, Thu, 2pm CET, will tell us about his recent paper (👇) [joint work w/ @neural-reckoning.org]. Want to attend, send an empty email to virtual talk-link-request@cmclab.org to get the link!

- when doing neuroscience projects I often advocate for computational modelling, followed by data analysis to test model's predictions. however a few times now I have had pushback from collaborators/reivewers suggesting it would be better to do the data analysis first, then the modelling. thoughts?

- Personally I think this is actually very valuable. 'Conceptual models' can easily ignore important details and may not work in practice. Coding it up (i) makes the details explicit, (ii) ensures they are compatible, and (iii) clarifies to everyone else _exactly_ what the model is.

- My new gig is PI of the CANN group at Trinity College Dublin and University of Oxford (50/50). Funded by the UKRI Future Leaders Fellowship, we'll be recruiting postdocs, PhDs and an RA in Dublin and Oxford soon. So exciting! @oxcin.bsky.social @tcddublin.bsky.social @ox.ac.uk @tcdscss.bsky.social
- Great read as always. There is clearly accelerating tension between ever more complex computational approaches applied to brain data and actually figuring stuff out about the brain.
- Just published my review of neuroscience in 2025, on The Spike. The 10th of these, would you believe? This year we have foundation models, breakthroughs in using light to understand the brain, a gene therapy, and more Enjoy! medium.com/the-spike/20...

- At the Bernstein Conference 2024, Jeremie Lefebvre and I organized a workshop on the computational consequences of neural heterogeneity. Now, slightly more than a year later, we funneled the emerging discussions into a perspective piece: www.cell.com/neuron/fullt...

- ...of how many model neurons are needed is an interesting question! I assume it depends on what level of the complex hierarchy of brain behavior is being studied. (I should stop here, as I am not the expert - you have extensive experience in this :) I'm fascinated in the subject

- Thanks for reading the article! 1. The multi-billion parameter model discussed in the article was developed by Meta but then fine-tuned by neuroscientists (for research). This could become more common, or neuroscientists could start to train their own "foundation" models from scratch.
- 2. Brains are massively complex, but if our goal is to understand them, then building scale models may not be the best approach. In physics, many breakthroughs have come from abstracting away complexity, as this article highlights! doi.org/10.1111/ejn....

- Totally agree with Marcus on this. Besides, I think every method should be introduced with an “intuition paper” first that uses toy models to show what’s actually happening and how *not* to interpret findings from the subsequent “real” analyses. We sometimes do this now but nowhere near enough.
- Toy models, just in time for Christmas! Excited to share my first article for @thetransmitter.bsky.social #neuroskyence
- It's not even an "intuition" it's the most basic test. If your method fails in the simplest possible synthetic data, how can it possibly work on real data? I'm always amazed that this isn't the absolute minimal standard required. So much wasted time on analyses that just don't work.
