Diffusion MRI (dMRI) is a powerful tool to study white matter maturation. In our new preprint, we process and distribute a new resource of >24,000 ABCD dMRI scans using open source tools! We then evaluate how methods shape inferences about development. 🔗 www.biorxiv.org/content/10.6...

Cognition is inherently dynamic, yet most task-fMRI analyses treat it as static. My recent paper in NeuroImage introduces Probabilistic Cognitive State Modeling (PCSM). Paper: doi.org/10.1016/j.ne...

Want to study how the brain supports social behavior + cognitive control? The ASCEND Lab (CU Anschutz Psychiatry) is hiring a full-time Research Coordinator (TMS/fMRI, cognitive neuroscience). Great prep for a career in research and PhD/MD/industry paths. Apply here: cu.taleo.net/careersectio...

Excited to share my new preprint on Probabilistic Cognitive State Modeling (PCSM), a method that connects cognitive theory and neuroimaging by modeling serial-parallel processing, demand, and bottleneck dynamics over time.

Probabilistic Cognitive State Modeling (PCSM): Decoding Latent Spatiotemporal Dynamics to Reveal Serial-Parallel Processing, Cognitive Demand, and Serial Bottleneck in Task-Based fMRI

Studying flexible, adaptive transitions between cognitive tasks and serial-parallel processing under changing task demands has been a central focus for understanding human cognition. Advances in neuro...

Next week, Wed Oct 1 at the usual time (1:30PM EST) and zoom link, we'll host Miriam Klein-Flügge @mkflugge.bsky.social speaking on "Computation, neuromodulation and mental health relationships in affective decision-making." DM me your email if not on our list for the link. Hope to see you then.

Great news: just received the NOA for a K23 grant from NIMH! This project will test whether brain stimulation (TMS) can target core symptoms of psychopathy, which are implicated in a substantial proportion violent acts nationwide.

New publication with @juldugre.bsky.social finds that functional brain patterns implicated in executive functioning differentiate conduct problems and callous-unemotional traits. t.co/6Bdz1IrtHW

Can specific cognitive control functions differentiate CU traits from CP? Analysis of RCT data suggests CU traits associate with better performance during passive control (non-response) but worse performance during selective control. doi.org/10.31234/osf...

Fellow scientists: If you are going to make broad public pronouncements based on your results, please have someone check your math first. The general population is losing faith in science, and reversals like this are a big part of the problem.

Entropy is one of those formulas that many of us learn, swallow whole, and even use regularly without really understanding. (E.g., where does that “log” come from? Are there other possible formulas?) Yet there's an intuitive & almost inevitable way to arrive at this expression.

Honored and excited to meet my fellow awardees next week!

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!

Are callous-unemotional (CU) traits purely affective, or do they also involve cognitive processes? A recent RCT finds CU traits uniquely linked to cognitive-affective interaction difficulties that also associated with antisocial behavior. doi.org/10.31234/osf...

Be wary of overconfident people who know just enough to think they are experts, but not enough to understand the limitations of their own knowledge. Intermediate levels of scientific knowledge are associated with overconfidence and negative attitudes towards science. www.nature.com/articles/s41...

Why is everyone talking about localization these days? Where did this come from? Should I even care? @psychonetrics.bsky.social @pessoabrain.bsky.social @dscheinost.bsky.social & I reflect on how past practices influence where we are today & how recent trends prompt us to reframe our work

A fantastic opportunity if you're looking to level up those #neuroimaging stats skills ✨ April in Salt Lake City!
