Thrilled to announce that this fall I’ll join @marwimber.bsky.social’s lab at @glasgow.ac.uk as a Marie Skłodowska-Curie Postdoctoral Fellow!

Grateful to the @ec.europa.eu for supporting my research on how active remembering shapes memory 🧠

Noradrenaline causes a spread of association in the hippocampal cognitive map - Nature Communications When forming a cognitive map, a trade-off exists between facilitating novel inferences and storing veridical copies of past experience. Here the authors show that the neuromodulator noradrenaline sets...

Very pleased to share that our study “Noradrenaline causes a spread of association in the hippocampal cognitive map” is out in @natcomms.nature.com (my final PhD paper, only 3.5 years post PhD! 🙃)

Europe’s future is built on knowledge.

For 30 years, the Marie Skłodowska-Curie Actions (MSCA) has supported over 150,000 researchers, including 23 Nobel Prize winners.

This programme is built on curiosity, openness and excellence.

Happy birthday MSCA!

How does the brain replay memories during sleep?
Excited to share our new preprint, the outcome of an extensive effort led by Johannes Niediek, showing that reactivation of human concept neurons reflects memory content rather than event sequence.

With some trepidation, I'm putting this out into the world:
gershmanlab.com/textbook.html
It's a textbook called Computational Foundations of Cognitive Neuroscience, which I wrote for my class.

My hope is that this will be a living document, continuously improved as I get feedback.

We show that the HPC supports coincidence detection across VTA and lPFC in service of novelty-evoked invigoration. Stay-tuned for how these circuits are altered in psychosis risk.

🧵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 🧠

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.

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.

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 💡

Stress enhances memory for previously encoded events depending on stressor recall Peer-reviewed scientific journal publishing basic neuroscience research in the areas of neuronal plasticity, learning and memory

🚀 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!

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...

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 💡
