Can you make your life feel “longer” in retrospect? Add a dose of change and novelty in the present to later expand memories of your past. Excited to share our work on how dopamine-related processing bends memory to reflect the passage of distinct events. newsroom.ucla.edu/releases/can...

Can dopamine bend time to shape memory?

The brain may use dopamine to expand time between distinct events, enabling us to remember unique episodes.

Happy to share that I will give a colloquium talk at the Heymans Institute for Psychological Research, University of Groningen, on June 2 I will present my work on how experiences are segmented into meaningful events, and how contextual stability and working memory contribute to this process ✨

Under stress, two things happened in the hippocampus: 1) Less reactivation of the prior related memory during new learning 2) Greater neural dissimilarity between overlapping events To put it another way, stress pushed related memories apart instead of pulling them together.

In collaboration with @monicarosenb.bsky.social , we showed that individual diffs in LTM encoding is uniquely predicted by inter-electrode correlations even controlling for working memory abilities. This suggests that WM & LTM encoding are separate abilities coded by different neural signatures! 1/n

I’ll share findings from my recent research — which has been accepted for publication in Psychonomic Bulletin & Review — on how contextual stability, rather than prediction errors, might play a more dominant role in structuring episodic memories. Hoping to see you there! 😊
