Functional Connectivity Heterogeneity and Consequences for Clinical and Cognitive Prediction AbstractFunctional connectivity is frequently used to assess dynamic brain functioning and predict individual differences in behavioral outcomes, such as psychopathology. Inferences from functional co...

Neat registered report from @mattmattoni.bsky.social @dvsmith.bsky.social @mindimager.bsky.social and @olinotom.bsky.social diving into the tension between nomothetic (group-level) v. idiographic (individual specific) in functional connectivity models.

🧪 BREAKING (good news): Senate subcommittee says NO! to Trump's proposed slashes to NASA & NSF funding.

Today, the subcommittee said to keep NASA + NSF funding at $33.9 billion, the same as in FY24.

See 7:15 below. Full Senate appropriations committee meets tomorrow about it.

We share open data (N=353) from a novel task linking risk and ambiguity decisions.
This dataset lets researchers test how people update beliefs under uncertainty — and an empirical paper (led by Jeff Dennison) is coming soon! (2/2)

Commentary: "Your Brain on ChatGPT" Preprint A commentary on a viral research paper evaluated the effects of GPT on Brain covariation.

The preprint "Your Bran on Chatgpt" has gotten tons of attention. Being on a 14hr flight, I read the 100+ paper & wrote a review. TL;DR: claims are unsubstantiated.

Let me know where you agree / disagree.

A fun session full of interesting talks from all the speakers. Thanks to everyone that climbed all those stairs to come & pack the room!

The ABCD Study 6.0 release is finally here! 🧠 Apply for data access here @theabcdstudy.bsky.social www.nbdc-datahub.org

Would really spice talks up if every speaker had to present after taking a bite of a the bomb wing.

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.

Unsurprising, tbh. Same issues and hype for EEG study re: “10min break between meetings” from MSFT the other year.

Many worthwhile options. 1) is the theoretical framework over/underrepresented? 2) contract irrelevance? 3) measurement error reducing effects? 4) auxiliary theories do not hold? 5) pub bias in prior lit? 6) how can results be re-evaluated in secondary data or data with improve power?

The history and future of resting-state functional magnetic resonance imaging - Nature This Review provides an overview of the history of resting-state functional MRI research, which has helped to reveal the spatiotemporal organization of the brain, and discusses how it can contribute f...

When I first started working with resting state fMRI as a postdoc, there was a lot of skepticism about what we could learn from it. 20 years later, it's hard to imagine where the field of neuroscience would be without it. Here's a summary 🧠 www.nature.com/articles/s41...

Thanks to everybody who chimed in!

I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist.

So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>

Happened only two times this last week. 😂

Data Sharing - ABCD Study

FYI, if you want to be prepared to apply for the next ABCD Study data release, prepare for these new NIST security requirements 🧠: @ohbmofficial.bsky.social abcdstudy.org/scientists/d...

In related news, maybe you should stop directly messing around with coefficients in the first place! Just talked to a student who was told by their advisor that they should use a continuous scale for a categorical thing because otherwise “the analyses get too complicated.”>

The analytics: “trust us, bro. We, like, got help from DOGE.”

Ron Wyden has always represented OR well

Are we paying too much for biomedical research? Trump's attack on NIH

Wonderful explainer on indirect costs by Dick Aslin open.substack.com/pub/dickasli...

Indirect Costs at NIH . . . I wasn’t planning on spending part of a Saturday writing about cost accounting principles and the like, but NIH-world was hit with a doozy of a policy announcement on Friday night:

Great analysis of the indirect cost rate announcement by @stuartbuck.bsky.social

“Of course, the whole effort would be incredibly tedious, and you’d need to involve subject-matter experts rather than just people who are good at computers but don’t know anything about government, science, or universities.” ‼️

New data alert! Monitoring the Future Panel core data for young adults (ages 18-30) from 1976-2021 are now available through the @icpsr.bsky.social @nahdap.bsky.social data portal: bit.ly/MTFcore

The design of the task is to literally piss people off. Hilarious 😂😂
