This is your brain on Ritalin. Got your attention? Stimulant medications like Ritalin (methylphenidate) do, but not in the way you might think. They don't act directly on the brain’s attention systems! Find out what's really happening in @cellpress.bsky.social. doi.org/10.1016/j.ce...
Ever wondered if your interesting brain-behavior correlation was over- or under-estimated due to head motion, but were afraid to ask? We’ve created a motion impact score for detecting spurious brain-behavior associations, now available in Nature Communications!

Had a great time with Gonzalo Rivera and @crimoral.bsky.social and many others at the SimNIBS workshop. A lot of discussion on #TMS, #tDCS, and #tACS!
what a great week we had in the workshop!, a lots of fun and a lots of learning! Thanks a lot @miles2708.bsky.social for coming all the way to Stgo, your kindness and generosity! Thanks also Gonzalo for organizing!
Announcing the next AFNI Bootcamp: Sep 23-25, 2025.
Free, open & virtual.
This "Part 1" will focus on basic visualization and single subject FMRI processing, including discussions of alignment, templates, regression, ROIs and quality control.
Details & registration: afni.nimh.nih.gov/bootcamp
Is precision functional brain imaging in babies possible? YES! We show this in not one but two new preprints out of WashU and @umn-midb.bsky.social! 1️⃣: www.biorxiv.org/content/10.1... 2️⃣: www.biorxiv.org/content/10.1...

I still get chills
Meet Mike
*30+ years severe depression
*first hospitalized @ 13y
*20 meds
*3 rounds of ECT
*2 near-fatal suicide attempts
Mike felt joy for the first time in decades after we turned on his new brain pacemaker or PACE

New paper hot off the press www.nature.com/articles/s41...
We analysed over 40,000 computer vision papers from CVPR (the longest standing CV conf) & associated patents tracing pathways from research to application. We found that 90% of papers & 86% of downstream patents power surveillance

AI and Fraternity, Abeba Birhane, AI Accountability Lab I envision a future where human dignity, justice, peace, kindness, care, respect, accountability, and rights and freedoms serve as the north stars that guide AI development and use. Realising these ideals can’t happen without intentional tireless work, dialogues, and confrontations of ugly realities – even if they are uncomfortable to deal with. This starts with deciphering hype from reality. Pervasive narratives portray AI as a magical, fully autonomous entity approaching a God-like omnipotence and omniscience. In reality, audits of AI systems reveal a consistent failure to deliver on grandiose promises and suffer from all kinds of shortcomings, issues often swept under the rug. AI in general, and GenAI in particular, encodes and exacerbates historical stereotypes, entrenches harmful societal norms, and amplifies injustice. A robust body of evidence demonstrates that — from hiring, welfare allocation, medical care allocation to anything in between — deployment of AI is widening inequity, disproportionately impacting people at the margins of society and concentrating power and influence in the hands of few. Major actors—including Google, Microsoft, Amazon, Meta, and OpenAI—have willingly aligned with authoritarian regimes and proactively abandoned their pledges to fact-check, prevent misinformation, respect diversity and equity, refrain from using AI for weapons development, while retaliating against critique. The aforementioned vision can’t and won’t happen without confrontation of these uncomfortable facts. This is precisely why we need active resistance and refusal of unreliable and harmful AI systems; clearly laid out regulation and enforcement; and shepherding of the AI industry towards transparency and accountability of responsible bodies. "Machine agency" must be in service of human agency and empowerment, a coexistence that isn't a continuation of modern tech corporations’ inequality-widening,
so I am one of the 12 people (including the “god-fathers of AI”) that will be at the Vatican this September for a two full-day working group on the Future of AI
here is my Vatican approved short provocation on 'AI and Fraternity' for the working group
Brain Surfaces of 70 primate species

To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised!

AI performance is known to scale with logarithm of sample size (Kaplan 2020), but in many domains, sample size can be # participants or # measurements...

We have argued that the brain’s Action Mode Network controls functions required for goal-directed behavior. www.nature.com/articles/s41...
Now, in new work, we show that AMN contains distinct subnetworks for making decisions, implementing actions, and processing feedback. doi.org/10.1073/pnas...
Alert!!!!
“An Action Networks Model for Pain”
We propose a new model for chronic pain — and highlight two functionally connected cortical networks that could revolutionize how we treat it.

It’s the ABCD Release time too!

That means the ABCC 3.0.0 is live!!!
The largest release yet from the ABCD-BIDS Community Collection.
This is going to be fun!!
👇 Let’s dig in.
My med school textbook says stimulants like Ritalin treat hyperactivity by “stimulating” the brain’s attention and cognitive control systems. We studied children taking stimulants in the ABCD Study, and the largest differences were actually in arousal and reward networks! Check out our preprint!

It's finally here! Use the Network Correspondence Toolbox to help contextualize your neuroimaging findings 🧠
The result of a large (42 authors!) collaboration:
"Go Figure: Transparency in neuroscience images preserves context and clarifies interpretation"
arxiv.org/abs/2504.07824
TL;DR: The FMRI world can (and should) improve results interpretation and reproducibility *today*, via transparent thresholding.
Taking full advantage of new advances in brain imaging technology will require more collaboration between engineers and neuroscientists, writes @lauradata.bsky.social in the latest for our human neurotechnology series.
