Longitudinal fMRI reveals altered developmental trajectories of functional network organisation associated with adolescent cannabis use https://www.biorxiv.org/content/10.64898/2026.10.20.760368v1

More ideas for Andy to raise to annoy the far right: - Joining the Euro (obvs). - All beer to be sold in 500ml or 250ml units. - All cricket grounds to be replaced with boules clubs. - All chip shops only allowed to serve modules frites. Come on Andy!

Likely the most important thing I've ever written — if you're an academic and the AI mania unsettles you, here's my best shot at presenting some intellectual tools that might help you articulate why. arxiv.org/abs/2610.27251

Well. 🤷🏼‍♂️

My gym this week. Honestly - best gym I've ever been to! Sal - Cape Verde Islands.

New conference paper on use of AI agents in fMRI contains at least one AI-hallucinated/non-existent reference (number 14). FFS. I mean, come on guys, even undergrads know to check their references these days. www.avestia.com/EECSS2026_Pr...

Well done all you radical Professors! Great job. 👍 See you at the next meeting.

This is an astonishing @pubpeer.com post: pubpeer.com/publications... The author compares data points from a figure against random numbers produced with a certain seed, finding r > 0.999999996! 🫠 Could there be any possible innocent explanation? The paper: www.nature.com/articles/s41...

Hey kids. Ever wondered what a 'persistence homological scaffold' really is? If you're a psychologically healthy person, then probably not, but if (like me) you have the acquired psychic trauma caused by reading psychedelic neuroscience papers, then this post is for you! medium.com/@m.b.wall/wh...

Neuron continues its three-part series on neuroscience and AI with “Neuroscience and AI: Emerging Synergies”. Explore how brains and AI are converging, from language models and scientific discovery to more brain-like AI systems. The synergy deepens. www.cell.com/neuron/issue...

Just the tiniest little man ever. Miniscule. Sub-atomic. Planck-scale.

I genuinely mean this. I cannot imagine a more bleak dystopian notion than the idea of all art being turned into slop designed to coddle my exact perceived intentions. The point of literature, film, music, and art is to be exposed to the interior lives of others. Who are these people.

the tech industry is about to invent books

Wow, what a dilemma. Vibe-coded apps are heinous obviously, but if it's screwing Adobe...

The tiniest, saddest little man ever. Miniscule. Sub-atomic.

Me: I need to keep this computational environment stable for reproducibility purposes, so I'm just going to switch off automatic system updates for now IT Services:

Column on Greens, anti-Zionism and why the people who pathologically hate something are not the most reliable people to define it accurately www.theguardian.com/commentisfre...

This is horrific. Govt funding for psychology, linguistics, archaeology and many other fields just... gone. Zero. Nada. Cancelled. YIKES.

Teen cannabis use linked to flattened cognitive development in large U.S. study

Tory party not really disproving the "they're still mad as pants" allegations then.

Yes please. 🇪🇺

So, yesterday I dropped a quote from Ghostbusters (1984) into a message to a Gen-Z colleague, which was met with total incomprehension (obviously, what was I thinking?), but then followed with: "Sorry, I don't watch old movies." Oof. The casual brutality.

No hell deep enough for this.

terminator reboot but it’s humans going back to 1999 to make sure Y2K happens so the internet dies forever

We're now recruiting UCL MRes/MSc students (eg Cog Neuro / Brain Sciences) for the 2026/27 academic year to join several research projects involving psilocybin and nitrous oxide. If you're a student on one of these programmes and would like to find out more, email ucjurgm@ucl.ac.uk or dm here 😊

We got a new review/model on why we think psychedelics might be particularly useful in the treatment of anxiety-related disorders. link.springer.com/article/10.1... Good work @htmcgovern.bsky.social on carrying this through the finish line.

God, grant me the courage to change the things I can and incredible new powers to change the things I can't.

This is true! I received a very apologetic email from a student once saying they couldn't afford the fee to download my paper. 💔 I was absolutely delighted to send her a free copy!

- Honestly my dear grandchildren, you’ll never believe how low rates were in the 2010s. - at least you built a load of infrastructure when borrowing costs were so low grandad? Right? Right?

Morning!

after some in-depth discussions with my lab and also drawing on conversations on here, we've edited our new policy on AI usage in my lab feel free to adapt or re-use with attribution, or to reply to tell me how awful this policy is lol

So… we just found out that GPT sol can complete a complex online behavioral/cognitive study producing nearly indistinguishable behavior and subjective reports… right as we are about to launch. Is this doomsday for online cognitive testing?

"i have created the machine that thinks." you fucked up a perfectly good graphics card is what you did. look at it. it's got anxiety

Okay, this is an incredibly, incredibly cool discovery. The brain stem is a different organ?

🧠 We are hiring 2 RAs to join a decoded neurofeedback project using fMRI & fNIRS to modulate emotional states. Please RT 📅 Deadline: Oct 8, 2026 🔗 www.bcbl.eu/en/join-us/j... #AcademicJobs #Neuroscience #fMRI #fNIRS

Great. Now do school uniforms. Ridiculous we make kids dress up as little executives when no-one even wears these things anymore. Ties are just a big arrow pointing at your dick.
