One of the lab's original Day 1 "dream" projects is now out as a preprint! Using a custom set of stories with fMRI, we showed that top-down attention can shift mPFC event boundaries to align with different kinds of narrative boundaries biorxiv.org/content/10.110…

Hannah's biggest paper from her PhD is preprinted! She created a new paradigm for learning complex sequences of locations (using VR), and then showed that cuing a location activated brain representations of nearby locations, with different temporal scales in different regions!

I'm so unbelievably excited to share our latest work, the heart and soul of my PhD! With @ChrisBaldassano & @mariam_s_aly We show that temporal structure is represented bidirectionally and hierarchically across the brain to guide multistep prediction 👇 biorxiv.org/content/10.110…

When we anticipate the future, several brain areas show graded representations of the future and the past. These representations reach further in hippocampus and more anterior regions. Proud of this work by @hannahtstoll, a collab w/ @ChrisBaldassano! biorxiv.org/content/10.110…

I'm so excited to share this work with @mariam_s_aly and @ChrisBaldassano! We explore how memory for temporal structure changes with consolidation to support multistep anticipation. Make sure to read to the end for some fun RT modeling! ✨️ psyarxiv.com/x2f7s
Mariam Aly@mariam_s_aly

How are memories transformed over time to enable anticipation of the future? With consolidation, multistep anticipation becomes more efficient but less perceptually detailed. Proud of @hannahtstoll for leading this collaboration w/ @ChrisBaldassano! psyarxiv.com/x2f7s

The final version of this work is now published at eLife! The Editor's evaluation gives a great summary of why we are so excited about this new kind of paradigm for studying sequential memory elifesciences.org/articles/82599

New preprint w/ Kevin Ochsner: Matt Sachs @sachsm53 worked with film score composers to create emotional music, and found brain regions that: -track emotional dynamics -represent emotional information -are sensitive to the recent emotional context! biorxiv.org/content/10.110…

Super excited to announce that our paper on how schema representations benefit memory performance during encoding and retrieval is now out on eLIFE!! Check out the link to find an updated paper! doi.org/10.7554/eLife.…

NEW PREPRINT with @ptoncompmemlab @Columbia_DPML @ChrisBaldassano!! How is our prior knowledge about the structure of naturalistic events represented in the brain, and how does this support memory encoding and retrieval? --- (1/10) biorxiv.org/cgi/content/sh…

Not enough superlatives out there to describe my excitement that I’ll be starting my own lab @UCRiverside Psych in 2023! I use EEG, fMRI, & behavior to study context + memory in younger and older adults. I’m hiring a lab mgr, grad students, & postdoc. Lmk if you’re interested!

Jamal's just-published paper shows for the first time that the brain divides up instrumental music into discrete events, similar to what happens with narrative stories! This required lots of careful technical work by Jamal and help from a great team of collaborators
Jamal Williams@jay_neuro

So proud to announce that our paper on how the brain represents high-level event structure in music is now out in JoCN! We are very grateful to our reviewers that suggested additional analyses that led us to new discoveries based on our original findings.
