🚨 🧠 We have a new preprint out where we studied which brain networks are engaged during mental imagery and self-generated thought. We used a precision fMRI approach along with multidimensional experience sampling (mDES) to get trialwise self-reports from each participant about what they imagined.

I am incredibly proud to share my first, first-author paper as a postdoc with @benhayden.bsky.social . How does the human hippocampus, known for encoding concepts, represent the meanings of words while listening to narrative speech? www.biorxiv.org/content/10.1...

I want to highlight a special issue in honor of Sarah DuBrow, a brilliant scientist and dear friend who passed away in 2022. We contributed a paper in which we disentangled the importance of temporal and causal relationships while participants recalled the non-linear narrative, Memento. 🧵 ⬇️ 1/9

#Neuroimaging crowd, hear me out! 👀 Did you ever want to add #EyeTracking to your #fMRI study but found it too much hassle? Got existing data you’d love to add eye tracking to? Consider trying out MR-based eye tracking (i.e. inferring gaze from eye voxels)! Here is a 🧵 with a few options!👇 1/9

It takes a LONG time to manually score autobiographical memory narratives for internal and external details (in Autobiographical Interview terms). Here, we report a new model that automates this process, matching manual scorers, but much faster (5s instead of 10m per memory). osf.io/preprints/ps...
