Is resting-state functional connectivity (rsFC), cortical thickness (CT), or cortical volume more effective at capturing sex and gender differences in the brains of preadolescents?

Check out our new article (doi.org/10.1016/j.dc...) now out in Developmental Cognitive Neuroscience.

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!

It took me 2 minutes to write about how this proposed rule would eliminate all foreign PhD students, who are a critical part of US science and technology, and drive US innovation and economic growth

Comment period ends on Monday for a proposed rule change that would terminate student visas after 4 years. It also puts limits on exchange visitors and reps of foreign media, and shortens the length of time at the end of the visa from 60 days to 30 days.

It is really disheartening to see the men who are in charge of science and healthcare in the United States stand before us all and spew misinformation about autism.

To claim that genetic background isn’t the overwhelming contributor to autism is egregious.

The FDA is taking their reviews of new drugs behind closed doors, with Director Marty Makary replacing vetted and publicly transparent deliberations with "panels of handpicked scientists who support his views."

This is a miscarriage of science, and a betrayal of public trust in service of MAHA.

Under Trump, FDA seeks to abandon expert reviews of new drugs

Advisory committee meetings help FDA scientists make decisions and increase public understanding of drug regulation, and abandoning them doesn't make sense, former officials said.

NIMH Data Archive is now also imposing NIST/ISO requirements (like NBDC). Not sure how many labs actually have the resources to meet these requirements. Is the golden era of open brain imaging data basically over?

Longer fMRI brain scans boost reliability—but only to a point

Around 30 minutes of imaging per person seems to be the “sweet spot” for linking functional connectivity differences to traits in an accurate and cost-effective way.

"Simple" tools in the same loop as the experiment along with thoughtful, common sense approaches (like focusing on individuals instead of consortia). That's really powerful. That's how you translate. And there aren't a lot of groups that do all of experiment and tools and theory well.

Be honest. You've written the same thing a dozen times.

But in my defense, I felt like I did my part -- wrote about a tool. Made some observation. Now let other people figure out how to apply it. Fin [at least my contribution].

That's such a copout! How do we get away with saying these things? 3/

But every one of those papers has the same throwaway statement somewhere.

It goes sort of like this: "in principle, this tool could be used in future studies for biomarkers or for helping better understand [your favorite disorder]."

Those statements are trite and essentially meaningless. 2/

I've been thinking a lot about the preprint in terms of my own career. I grew up academically in computational labs. My papers were abstract early on and they only got more abstract as I progressed. The model was: find a new exciting mathematical tool. Apply it to brain imaging data. Write it up. 1/

This is the future. The reality of biological #psychiatry. We listen to the patient, create a personalized map of their brain, use algorithms to disrupt stuck networks, and adapt the stimulation over time while continuing our quest to understand those networks.

Damien Fair @drdamienfair.bsky.social · Aug 10

Now with PFM, prior cortical stim work by @ziad-nahas.bsky.social for depression could be patient specific.

We developed the end-to-end minimally invasive PACE used by @drdaviddarrow.bsky.social to place electrodes directly on Mike's salience, default, fronto-parietal, and action mode networks.

The language 🧠 areas are selective for language relative to many forms of reasoning (arithmetic, social, semantic, etc.).
@hopekean.bsky.social has now shown that even formal logical reasoning—the domain that is perhaps the closest to language—neither engages nor requires the language system!
