🧵Our new preprint shows how the brain develops to transform how kids, teens & adults represent & navigate their world: shifting from local, moment-to-moment memories in childhood to integrated, global cognitive maps in adulthood 🧠

Thrilled to see this paper out! It's the culmination of a project begun in the depths of the pandemic with Sabrina Karjack and @zoengo.bsky.social . We continue our exploration of how children generalize when their episodic memory is not yet mature.

The dependence of children’s generalization on episodic memory varies with age and level of abstraction - Nature Communications
Children’s ability to generalize from episodic memories varies by both age and the level of abstraction. Here, the authors show that lower level generalization increasingly depends on episodic memory with age, whereas higher level generalization shows no such relationship.

How does cortisol tune brain networks to form strong emotional memories? Excited to share new work led by amazing former RA Flory Huang w collabs Rajita Sinha and @toddc.bsky.social #neuroskyence www.science.org/doi/10.1126/...
Dynamic brain mechanisms supporting salient memories under cortisol
The stress-related hormone cortisol alters dynamic brain networks predicting memory and arousal to promote emotional memories.

Our new paper is out! Valentina Krenz et al show that the amygdala response during the initial encounter of an emotional event boosts subsequent remembering through a more precise reinstatement of the event representation during subsequent encounters 💡

🚀 Big milestone for Antonia Lilja! Her first first-author paper in her PhD is now online🔥 Findings show that #stress enhances #memory for preceding neutral events—but only if the stressor itself is well remembered. No cueing effects found. Check it out!

New publication from our lab! 👀
We found that memory enhancement from PEs depends on the brain's neural state: theta/alpha activity & pre-error reactivation are key. TMS over the superior parietal cortex altered response bias but not PE-related memory effects 💡

Prediction Error-Related Memory Enhancement Depends on the Neural State Surrounding the Prediction Error Event
Prediction errors (PEs) can enhance memory for preceding events. While such PE-related memory enhancements are critical for understanding adaptive memory, their underlying mechanisms are not fully und...
