I am in Karachi. Let’s meet if you like to talk about brains, models, and machines!

1/ Why does RL struggle with social dilemmas? How can we ensure that AI learns to cooperate rather than compete? Introducing our new framework: MUPI (Embedded Universal Predictive Intelligence) which provides a theoretical basis for new cooperative solutions in RL. Preprint🧵👇 (Paper link below.)

📢Generative Models in Neuroimaging Survey We’re running a short survey on how neuroimaging (aka #OHBM) community defines, uses & evaluates generative models, from biophysical simulations to ML-based approaches 👉 t.co/lRQj4qmknO @ohbmofficial.bsky.social @ohbmtrainees.bsky.social

Jonny Smallwood @themindwanders.bsky.social was a beloved friend and mentor. He was taken from us too soon. His was a beautiful mind who understood the beauty of minds. As ever before, his kind voice guides me and his work will continue. We miss you Jonny. www.cbs.mpg.de/news/obituar...

What is consciousness, and could AI have it? It's an honour to be giving the 2025 Voltaire Lecture, this Hallowe'en (Fri 31/10), for @humanists.uk, at @conwayhall.bsky.social in London, 19:30-21:00 (also livestreamed) humanists.uk/events/volta... 👻

Very much forward to this @ohbmofficial.bsky.social

Do you like brain network hubs?🧠🌐✳️Do you like genes?🧬What about neurodevelopment?👶What if I told you the latest work by @garedaba.bsky.social and myself combined all of these?🤯🤯🤯 See Gareth's thread for a primer of our findings, then read the paper for the details! www.biorxiv.org/content/10.1...

Can a Universal Basic Income (UBI) become feasible—even if AI fully automates existing jobs and creates no new ones? We derive a closed-form UBI threshold tied to AI capabilities that suggests it's potentially achievable by mid-century even under moderate AI growth assumptions:

🧵Training binary or spiking neural networks is hard. Gradients vanish, surrogates are noisy, batchnorm is brittle. We propose a Bayesian approach based on KL divergence minimization—and it works. Paper: arxiv.org/abs/2505.17962 Work by James Walker & Moein Khajehnejad @neuro-ai.bsky.social 1/6

Why do brains rely on inference, uncertainty, and structure… while AI systems chase rewards in unstructured worlds? Are we missing something fundamental about how intelligence emerges? #NeuroAI #InferenceOverOptimization

Re-posting is appreciated: We have a fully funded PhD position in CMC lab @cmc-lab.bsky.social (at @tudresden_de). You can use forms.gle/qiAv5NZ871kv... to send your application and find more information. Deadline is April 30. Find more about CMC lab: cmclab.org and email me if you have questions.

Good news - the opening for a Research Officer role within our group is now open to all applicants! Please apply if you would like to join a great team to help with recruitment and assessment on a large project linking MRI with psychopathology! careers.pageuppeople.com/513/cw/en/jo...

"These findings provide a new account of the large-scale neurocognitive effects of psychedelics and demonstrate the utility of using machine learning methods in assessing state- and context-dependent neural dynamics and their association with psychological outcomes." www.biorxiv.org/content/10.1...

Interested in foundation models for #neuroscience? Want to contribute to the development of the next-generation of multi-modal models? Come join us at IVADO in Montreal! We're hiring a full-time machine learning specialist for this work. Please share widely! #NeuroAI 🧠📈 🧪

We are hiring! We're looking for a Research Office to help out with recruitment & assessment on a large-scale study looking at the relationship between brain imaging measures and psychopathology. Please forward this link to anyone who might be interested: careers.pageuppeople.com/513/ci/en/jo...

🚨 We are excited to announce that the next OHBM Australia meeting will be in Melbourne on Wednesday, 12th November, 2025! Stay tuned for more details 👀

🧩New study: "Network Constraints on 𝘪𝘯 𝘷𝘪𝘷𝘰 Synaptic Alterations in Schizophrenia" medrxiv.org/content/10.1... We map a prominent brain-wide pattern of synaptic defects in people with Schizophrenia using PET, then model the molecular, cellular & connectomic features shaping this pattern 🧵1/3👇

Can't believe I missed this until now - truly incredible work and real landmark paper in psychedelic neuroimaging!

One of the first real "wow" studies of 2025. Fascinating imaging work demonstrating how context and environment fundamentally shape a psilocybin experience.

Ok, kiddos. This neuroimaging study (Monash U) explains why why you shouldn't approach psychedelics - especially psilocybin - as a clubbing or party drug. It is so, so much more important than that. My foolish youth, corrected!

🧵 How do psychedelics shape brain activity? Our new paper presents the largest neuroimaging study of psilocybin to date—revealing how context structures psychedelic brain states. Title: Psychedelics Align Brain Activity with Context Paper: lnkd.in/gt-kMR6d A thread 🧵👇 1/n

Can we enhance interoception by controlling the heart? Thrilled to share our new study, led by @ashleytyrer.bsky.social , where we use computational modeling to show that blockading peripheral noradrenaline uniquely alters awareness of heart rate & breathing! www.biorxiv.org/content/10.1... 🧵👇

1/ "A science of consciousness beyond pseudo-science and pseudo-consciousness" is out now! it was a joy to coauthor this commentary with Àlex Gómez-Marin @behaviOrganisms for @NatureNeuro, in which we try find some positive lessons in the clash over IIT www.nature.com/articles/s41...

Can we use brain scans to identify biologically distinct "autisms"? And If so, how? In our latest cross-species study 🐭👨 with @iitalk.bsky.social we dive into these questions! Find out more here 👇👇 www.biorxiv.org/content/10.1... Thread below 🧵 1/n
