A paper in Nature Medicine reports insights into how the human brain reacts to different types of psychedelic drugs. These psychedelics appear to change how key networks in the brain connect, including those involved in higher-level thinking, sight and movement. go.nature.com/4mhgse6 #medsky 🧪

How do psychedelics alter brain activity? 🍄✨ A landmark study published this week in @NatureMedicine by CPCR researchers @FredBarrettPhD, @winstonian3 and a global team of collaborators analyzes the largest human psychedelic fMRI dataset to-date.

How do psychedelics work? AI gives us a glimpse. @danilobzdok.bsky.social and his international team just published the world’s largest study on psychedelics in Nature Medicine, using AI algorithms to analyze 500 brain scans (10 times more than previous efforts).

Teaser for upcoming paper... 🫣 Stay tuned!

Our paper at #NeurIPS 2025: 1) Pre-trained transformer models impose semantic structure on inputs. 2) More skewing of transformer processing as input uncertainty increases. 3) Spurious concept activations can predict hallucinations. arxiv.org/pdf/2509.069... #large #language #models + #safety

📢 job opening: software developer at Mila Quebec AI Institute & McGill As of now, my team is looking to hire a new technical staff member with abackground in a STEM area for running and curating existing AI analysis pipelines, as well as designing GUIs around them. Please DM or email me, with CV

1/11 Excited to share our @Naturestudy led by @leonooi.bsky.social @csabaorban.bsky.social @shaoshiz.bsky.social AI performance is known to scale with logarithm of sample size (Kaplan 2020), but in many domains, sample size can be # participants or # measurements... doi.org/10.1038/s415...

Our Nature paper on the hashtag#scaling hashtag#behavior and economics of hashtag#machine hashtag#learning predictions in high-dimensional brain scans is out ! Congrats to the whole team. www.nature.com/articles/s41...

Looking forward to speak at Yale University next friday. impact-mh.org/event/impact...

I am impressed by this book I am currently reading: Kissinger's posthumous work on: -strong anthropological views on the current AI evolution -modes in which #AI could take space as a physical and intellectual actor -how modes of decision making of humans and machines can coalesce and completment

Great opportunity to get generous postdoc funding to work at a Canadian university

Big congrats to our former postdoc Andrea @andrealuppi.bsky.social for earning the Brain Star Award for his work ! can-acn.org/brain-star-a...

Using multi-modal data from the UK Biobank, Zhou et al. delineate the phenotyping and brain basis of early risers and night owls at a population scale, showing links to habit formation and emotional regulation. www.nature.com/articles/s41...

#AUTISM “A data-driven revision of criteria ... grounded on clinical certainty, would complement what has historically been done by expert panels and ... humans, who can be wrong." @danilobzdok.bsky.social @mila-quebec.bsky.social @cellpress.bsky.social #AI nouvelles.umontreal.ca/en/article/2...

Jack Stanley shows how to tailor #LLMs for single-sentence prediction in #autism: www.cell.com/cell/fulltex... Great collabo with Eugene Belilovsky + Siva Reddy from @mila-quebec.bsky.social, and Laurent Mottron + Emmett Rabot

Trained language model finds repetitive behaviors and special interests are more indicative of an autism diagnosis than a lack of social skills. https://www.cell.com/cell/fulltext/S0092-8674(25)00213-2 @mila-quebec.bsky.social @Danilo Bzdo

Mila researchers Jack Stanley and Danilo Bzdok published a paper in the journal @cellpress.bsky.social. Their work uses LLMs to analyse data from written reports by medical professionals in order to better understand and improve how autism diagnosis is performed. mila.quebec/en/article/u...

Understanding #Parkinsons subtypes is key to more targeted RCTs & better therapeutics! 🧠 Our new study finds that LRRK2 PD patients show milder cortical atrophy, with preserved temporal & occipital regions compared to sporadic PD. #LRRK2 #dataviz www.medrxiv.org/content/10.1...

@oprah-winfrey.bsky.social and @michaelpollan.bsky.social make unmistakably clear: there is widespread interest in #psychedelics >1M views in less than a week, bravo !

My talk on “Neuroscience and AI: a symbiosis” @SimonsInstitute I start with a whirlwind history of metaphors for intelligence, spanning Hippocratic hydraulics, Hobbesian clocks, Cartesian dualism to Turing, telegraphs, Hopfield, and deep learning. simons.berkeley.edu/talks/surya-...

@evfedorenko.bsky.social at Berkley LLM workshop gave insightful talk today: -Broca / Wernicke s are speech areas, not language areas per se -language networks similar across 50 languages -most language voxel are INsensitive to semantics -lesion studies suggest thought intact but speech impaired

@suryaganguli.bsky.social gives great talk at LLM workshop at Berkley -LLM<->brain is still a new topic, less progress so far than LLM<->vision -lets train LLM foundation models of specific brain systems and then reverse engineer them -emerging paradigm: read-write experiments in brains+machines
