Bangalore, early Sunday

🔥Superb lecture by Ed Bullmore on schizophrenia and mental illness, now online as part of Petra Vertes' seminar series: www.youtube.com/watch?v=51t8...

Afternoon tea

1 am (only jet lagged people are going for a walk)

Midnight (Dubai)

I have now mastered the art of sitting in a chair for 16 hours

Waiting for the next grant to be awarded

Talairach Lecture - huge thanks to OHBM for putting this (very nervous) lecture online! youtube.com/watch?v=3iWp... OHBM 2025 Keynote Lecture Speaker: Paul Thompson Title: Talairach Lecture: Worldwide Collaboration & Artificial Intelligence in the Global Quest to Map Human Brain Diseases. 👇

So many fireworks went off last night that my air quality machine says avoid strenuous activity* * I was already avoiding it

That’s was close

Today's experiment ! :)

2 extremely tiny children about 4-5 years old came to the door on their own and I said “how did you get here” and the little girl said “I drove here”

Happy 🎃!!!

This could solve a lot of problems

I hope somebody somewhere made this bet and is going to make a shotload of money.

yes!! I feel like GPT 4o/5 is already connecting topics from applied maths to problems in neuroscience and computer vision. 2 examples: it helped link privacy in generative AI to Levy rotators [1] and Malliavin calculus [2] [1] x.com/PTenigma/sta... [2] aiandthebrain.substack.com/p/preserving...

"Quel sera l’impact de l’IA sur les mathématiques dans les prochaines années ?" [1] 🔥My colleague Marisa Acuña shared this great lecture on how AI is changing math research. 🧵👇🔥

🔥Amazing graphs in a new meta-analysis [1] of walking (steps / day) versus mortality + illnesses 🔥Walking ~7,000 steps/day (vs 2,000) is associated* with: ↓47% all-cause mortality, ↓25% CVD, ↓47% CVD death, ↓37% cancer death, ↓14% diabetes, ↓38% dementia, ↓22% depression, ↓28% falls.

Working with @enigmabrains.bsky.social datasets or conducting meta- or mega-analyses? Check out our software package, IBMMA, designed to facilitate analysis of neuroimaging big data. Excited the toolbox manuscript is now out! @ptenigma.bsky.social @jennistevens.bsky.social doi.org/10.1016/j.ne...

🔥 🎇 MAGNIFICENT guided tour of extremely fine scale brain structure + a visionary programme of research by renowned anatomist Dr Jacopo Annese - creator of The Brain Observatory in San Diego

Incredible resolution imaging of the human brain’s axons “looking like messy hair” (!) - Dr Jacopo Annese Lecture

🔥 DM me if you want to attend this wonderful lecture @2pm TODAY, we're hosting renowned neuroanatomist Jacopo Annese ! 🔥 Will be @ our lab @ the Marina at 2PM !

Has anyone managed to get ChatGPT 4o (or other AI tools) to make nice diagrams where the lettering* looks reasonable? Often 1 or 2 letters are distorted. I asked it to make this pic again and it got worse! *images are made with a diffusion transformer that doesn't know how letters should look !

OK first try at using Substack for course notes. You might like this if you're a lawyer/neuroscientist interested in math. I should have formatted it better but the animations are fun! aiandthebrain.substack.com/p/preserving...

🔥 Today's experiment ! 🔥 Generative AI models should not output your medical records, brain MRI, copyrighted article, artwork, or the piece of music you wrote

🔥CHECK OUT our NEW VIDEO 🔥🔥🔥!! 🔥Artificial Intelligence for Neuropathology Prediction, Dementia Subtyping, and Prognosis (8 min.) www.youtube.com/watch?v=Lq3E...

More Stein flow, with different kernels (bandwidth should probably be adaptive)

🔥Today's animations 💡Both Langevin diffusion + Stein flows are ways to model + sample from a very high-dimensional distribution (like images you are generate with generative AI) points represent embeddings of images 💡(coming soon) you can use them to test/improve generative model calibration

WRITING A NEW LECTURE on vision, diffusion, +surrogate transfomers (ViT/DiT/SiT) they all seem alike, with dh_t​=f_θ​(h_t​,t)dt+σ_t ​dW_t; in ViT + SiT, the “time” t corresponds to "layer depth"+each residual block applies an incremental transformation; in DiT+LDM, t is an actual "diffusion time"👇🧵

Why does the first time I get interviewed by the news have to be with 10 min notice, in an office with no lighting? 😆 But the nice thing is they covered the ARTEMIS project and it's picking up some steam! #science #WomenInSTEM local12.com/health/healt...

🔥 Fun animation for an upcoming lecture. (guess the topic) :)

DR JOHANNA BAYER (Radboud Univ Medical Centre) will be our guest speaker TOMORROW @11am Pacific. Please come and see us and bring your creative ideas and Qs. You are all welcome to come and please DM me so I can make sure you get in.

TO NOT GO COMPLETELY CRAZY with grant writing 40 hours/week, I've decided to do some extra lectures you're very welcome to come to if you like* (thread follows): 👇👇

#ASFNR2025 BEST PAPER awardee Shahriar Faghani (U Penn; pictured right explains how Conformal Prediction can be applied to deep-learning based brain tumor segmentation, yielding uncertainty estimates of whether image voxels contain glioma: 🎇Plenary lecture in Austin, TX today

What a treat to hear from not one, but two giants in their fields as keynote speakers at #ASFNR2025! Paul Thompson @ptenigma.bsky.social and Roger Stupp.

🎇BRAIN CANCER pioneer Roger Stupp explains how SONICATION (ultrasound) can help to get cancer drugs across the blood-brain barrier -> higher concentrations of anti-cancer agents in tumor tissue #ASFNR2025 plenary

Do not think of setbacks as failures. They are like stepping stones that help you on your path forward. * * a quote I heard today on BBC radio (by 李创业医生 Dr Li Chuangye)

🧠 Fantastic ENIGMA workshop on how the brain changes + can dramatically recover in eating disorders. 👇 Graphic (below) shows how eating disorders overlap: 🔵 Restricting subtype of anorexia nervosa 🟢 Avoidant/restrictive food intake disorder (ARFID) 🟡 Bulimia nervosa 🔴 Binge-eating disorder 👇

🔥ARE YOU INTERESTED IN ANOREXIA. EATING DISORDERS + the BRAIN? Join us 230-530pm tomorrow for a remarkable workshop with 3 world leaders in this field: 🔥What causes anorexia + binge eating? 🔥How are they treated? 🔥How does the brain respond to treatment? DM me if you want to come. 3 Talks 👇👇

OK I rehearsed it and it's 10 minutes too long, gah www.youtube.com/watch?v=o0St...

So I drove to the lab to record my lecture as I knew the internet wouldn't go out there, and sure enough the internet went out* *so the video is sellotaped together from the interrupted pieces www.youtube.com/watch?v=o0St...

Best play of the day

THIS IS AMAZING! Jamaal Jarrett runs it back.

Interesting that AI models for language+video use embeddings of dimension 300-768* when the number of conversations ever had by all humans is 10^22 bits; 10^21 bits of data are already on the internet. And people will keep finding ways to compress them further (active inference) *CLIP, SentenceBERT
