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.

Important and thoughtful talk from Abigail Marsh on psychopathy and how it often goes unrecognized in everyday life.
Worth watching: youtu.be/P2pU9UCxlKY?...
These properties are implicated in many psychiatric conditions, where difficulties may arise not only from which regions activate, but from how information processing is organized across the brain over time.
Using this approach, we estimate:
• Processing modes (serial vs parallel)
• Cognitive demand and resource allocation
• Cognitive bottlenecks that constrain information flow
PCSM builds on established methods for identifying recurrent brain activity patterns and extends them into a framework that allows us to derive properties of information processing directly from brain dynamics.
Cognition is inherently dynamic, yet most task-fMRI analyses treat it as static.
My recent paper in NeuroImage introduces Probabilistic Cognitive State Modeling (PCSM).

This position has been filled.
I just checked and the committee closed the link while going through the first round of applicants. I can respond here when and if it opens up.
All the best
Yes, the position is still open and we are continuing to review applications. We expect to begin scheduling interviews soon.
Please feel free to share your materials at the application link if you have not already done so.
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.

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.

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.
Thanks! I submitted this grant in May of 2024. Fingers crossed that you hear something soon.
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.

Happy to see Julio Peraza's lastest posted, "NiCLIP", using a CLIP model to improve 'reverse inference' prediction of task fMRI results based on peak coordinate data www.biorxiv.org/content/10.1... w/ @angielaird.bsky.social @neurozorro.bsky.social James Kent & JB Poline
🚨PSA for anyone using GPT in human subjects research🚨
A judge has ruled that OpenAI must retain ChatGPT and API data indefinitely, with few exceptions.
This might have implications for your IRB compliance and the security of your participants' data. 1/
"Thinking time —the time needed to concentrate without interruptions has always been central to scholarly work. It is essential to designing experiments, compiling data, assessing results, reviewing literature and, of course, writing. Yet, [it] is often undervalued."

The SSSP Early Career Event (online) is just one week away and a program packed with new research on psychopathy and callous-unemotional traits is waiting for you: check out the details and register to attend here: psychopathysociety.org/page/ECE2025
Happy to report this work was accepted for publication in the Journal of Affective Disorders and can be found here: doi.org/10.1016/j.ja...
See our new preprint focused on causal thinking for data analysis in neuroscience #causal #neuroscience #neuroimaging #datascience #poldracklab with Brian Caffo, Maya Mathur, and @russpoldrack.bsky.social (1/4)

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

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...
Great new review and meta analysis by @juldugre.bsky.social @drewwint.bsky.social showing that neural activity patterns differ between different types of aggressive behaviour correlates with implications for future research and potentially treatment: tinyurl.com/2ha4tn6m
Announcing a new week-long program for young computational neuroscience/ behavior professors to talk about rigorous science, mentoring, lab management, and networking in a stunning retreat setting. Do great science as a community and have fun doing so.
Researchers spend approximately 45% of their time on administrative activities related to #grants rather than actual #research. The current #competition in research #funding has significant drawbacks; evidence-based improvements of the funding system are required: www.pnas.org/doi/10.1073/...

The debate continues. This time Niels Janssen writes a very interesting take on the issue (but I'm biased):
