Clinical 7T gradients can go fast — but peripheral nerve stimulation (PNS) stops you at high-res fMRI. ⚡ Meet POPE 🌍: we reshape EPI pulses to dodge PNS exactly when it spikes → robust 0.3mm fMRI, seeing intracortical veins. 🧠 w/ @SiemensHealth 👉 doi.org/10.64898/202...
Excited to see this line of research continue to grow, from our initial findings in Psych Science to our follow-up work in JEP: LMC. Thanks, Nick, for the great write-up! Check it out if you’re interested in how experience can rapidly reshape attentional control.
We have recently published work in Psych Science and JEP:LMC showing a surprising relationship between initial capture and learned suppression of salient distractors. Ultimately, this has led us to believe that attentional control is much more flexible than often assumed. Read more on my blog!

🧠 New preprint! How does the brain build specialized, efficient representations as we grow up? We used manifold learning to track the "intrinsic dimensionality" (ID) of brain activity in ~800 participants (aged 3mo–53yrs), as they performed naturalistic tasks and rested/slept.

💡What makes some ideas spring to mind while others we have to reach for? We built an #NLP #fMRI #MachineLearning framework to find out. New study from our lab, led by @kaixiangzhuang.bsky.social out in @natcomms.nature.com 🧵 🔗 www.nature.com/articles/s41... #CognitiveNeuroscience #Fudan #ISTBI
Response duration tracking is now an option in jsPsych 8.3.0. Decide whether to trigger responses on key press (current default) or wait for key release to get both initial response time and response duration. We handle edge cases like multiple keys being pressed and tabbing away from the browser.
