Anatomical White Matter Tracts Span the Cortical Hierarchy to Support Cognitive Diversity Long-range white matter (WM) tracts support cognition by enabling communication between distant cortical regions, which are organized along a hierarchy defined by the sensorimotor-to-association (S-A)...

Ever wondered how white matter tracts actually map onto the cortical hierarchy and cognitionβ€”beyond the usual β€œprojection vs association” labels?
Our new preprint tackles exactly that! 🧠✨ doi.org/10.64898/202...

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!

Is the β€œstandard workflow” holding back fMRI analysis?

Mass-univariate analysis is still the bread-and-butter: intuitive, fast… and chronically overfitted. Add harsh multiple-comparison penalties, and we patch the workflow with statistical band-aids. No wonder the stringency debates never die.

I can't recommend this fantastic new review from @valeriejsydnor.bsky.social enough! It does an amazing job of synthesizing the current state of the literature and then looking forward to provide a fresh perspective on how to move this work forward in humans. Check it out!

ggplot2 4.0.0 A new major version of ggplot2 has been released on CRAN. Find out what is new here.

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN.

It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package.

Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

Zoomed out crowd shot of 34,000 people in downtown Denver with Colorado mountains in the background

Tonight an unbelievable **34,000 people** gathered for our Denver rally to take on billionaires and win our country back.

This was the largest political gathering in Denver since Obama in 2008.

Also bigger than the 2024 DNC.

And the largest ever rally in Bernie’s career (and obviously, mine too).

We think of white matter as the brain's highwaysβ€”uniform conduits between cortices. But what if we study development along tracts? Turns out the journey matters as much as the cortical destination! We're thrilled to share β€œTwo Axes of White Matter Development” www.biorxiv.org/content/10.1...

hey -- i'm hiring a postdoc! the ad will be up shortly, but looking for someone with network neuroscience experience (very broadly). the position isn't tied to any specific project/grant, so lots of flexibility in terms of what you'd actually *do*. hmu if you might be interested/want to learn more!
