We think of white matter as the highways of the brain. But when we followed development along those highways, we were surprised. The journey is more complex than we thought. My final PhD paper, “Two Axes of White Matter Development”, is now out in @natcomms.nature.com! 🛣️🧠✨

Such awesome work!! 🎉

I want to start by saying thank you, truly, to my friends, family, and so many good people who have reached out to check on me during this hard moment in Minnesota. I love you all. I am okay. See thread....

Wow, this is just so cool!! 🤩🧠

Tis a deeply felt experience for us all! 😅

Study: Long Breaks Tied to Dip in Cognitive Test Performance - UConn Today A joint UConn - University of Minnesota research study concludes that there may be some reality to the "summer slide" of dips in test scores follo ...

Finding it tough to get back in the swing of things after vacation? You're not alone! Our study found that U.S. adults show lowest performance on cognitive tasks like executive functioning after winter break
Thanks @uconn.bsky.social for this highlight!

A bit of happy personal news to kick off 2026 - take that student loans! 😊 Adding another ✨ huge plug ✨ for the totally life-changing NIH Loan Repayment Program (LRP). Check to see if you're eligible! So grateful for this privilege/support.

Congratulations @joelleba.bsky.social! This is really outstanding work! 🎉

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...

Very happy to share our paper on the "summer slide" in kid's cognitive test scores is out now in @pnas.org!
We find a replicable dip in performance across multiple domains of cognition in >23,000 kids across 4 datasets!

Check out the 🧵 from @ariellekeller.bsky.social below! 👇

Wow these are both super interesting! We did look at ADHD in one of the datasets in our study. Would be cool to see if there's variation when further split out by those with treatment vs. untreated as well.

We didn't see a significant spring effect in this study, but curious what your hypothesis might be on that!

Thanks so much Cobb! :) :)

Our paper on the ☀️ "summer slide" 🛝 is out now @pnas.org!

Summer slide is a replicable phenomenon across diverse datasets that's more than "forgetting" school material in vacation months, but effects of socioeconomic inequality are ➡️ 7x bigger! ⬅️

These results suggest that differences in functional connections in the brain might be a potential mechanism linking differences in the environment with differences in cognitive performance, something that we’ll be looking at in future longitudinal timepoints of the ABCD Study! /9

But how does this “exposome network” relate to important developmental outcomes, like cognitive functioning? We found that variation in the exposome network across kids was associated with variation in cognitive task performance across multiple domains of cognition. /8

Using cross-validation, we found consistent results across subgroups of children. This means we can tell what a child’s environment might be like just by looking at the functional connections in their brain! Our predictions were most accurate in cities with greater variability in the exposome. /7

This “general exposome network” was robust – we found similar brain regions were included in this network across different scans, when the participants were performing different cognitive tasks or resting quietly. /6

This procedure helped us identify a consistent “general exposome network” in the child brain, which drew its connections from many large-scale brain networks involved in a variety of functions. /5
