New paper w/ @_LeeJaeJoong_ in Nat Neurosci!🧠 We developed personalized fMRI predictive models tracking ongoing spontaneous pain in chronic pain patients, trained on 6+ mo. of densely sampled data. A true team effort. Deeply grateful to our participants! doi.org/10.1038/s41593-026-0…
New paper out! Revisiting the DMN's self-related processing from an embodied view🧠💪 Huge thanks to @choongwanwoo and @choninn_x for enriching my internal model with great insights and fun discussions along the way!
Our new paper is out in Current Opinion in Behavioral Sciences; a perspective paper on the DMN, titled "Embodying the default mode network: self-related processing from an embodied perspective"

(1/10) How do brain networks and cognition co-evolve as children enter adolescence?
While valuable, cross-sectional studies offer only a single snapshot of brain–cognition relationships, missing the dynamic changes that longitudinal designs can reveal.
We hypothesize that cross-sectional and longitudinal estimates may diverge, echoing classical Simpson’s paradox.
As illustrated below:
To test this, we analyzed longitudinal fMRI and cognitive data at baseline and Year 2 in ~3,000 individuals (ages 8.9–13.5) from the ABCD Study, spanning the transition from childhood to adolescence.

1/11 How does our brain's hierarchical organization impact its response to stimulation? We found striking differences between "high-order" networks (involved in complex cognition) vs "low-order" networks (handling sensory/motor functions) @NatureComms

During #pain, the sensory input is modulated by contextual information. @SuhwanGim @choongwanwoo &co show how expectation & sensory input are integrated in the human brain during #PainPerception, revealing its spatiotemporal architecture #PLOSBiology plos.io/4fsaanu

How do people track information flow through social networks? New research finds that extended periods of rest, like sleep, help people build abstract cognitive maps for efficient navigation of social networks. @marclluis @orielf @apaxon
