Excited to have Taylor's work with me and Daphna Shohamy out in Open Mind now: even at the end of an event, it's not too late to prioritize it for long-term memory!

Years ago my lab tried to brainstorm ways to separately manipulate low-level (texture/pattern) and high-level (scene/object) image properties, for studying visual representations in the brain. Thanks to imaginative work by PhD student Zall Hirschstein, we now have a stimulus set that does just that!

What happens when we learn a new shortcut between places we thought were unconnected? Hannah found that the hippocampus rapidly adjusts its representations of environments to join them into a connected map - excited to share this final paper from her PhD work with me and @mariamaly.bsky.social !

Does watching a movie over and over make events slower or faster in the brain? With Narjes Al-Zahli and @mariamaly.bsky.social we find that different regions actually change in different directions, e.g. visual regions show finer-scale event structure and STS shows coarser-scale structure!

How does the soundtrack of a movie change your memory of the story? New work led by @jayneuro.bsky.social finds that repeated musical motifs can reactivate neural patterns from earlier scenes, and reactivation is related to better subsequent memory!
