🧠 Paper out!

We investigated how hippocampal and cortical ripples support memory during movie watching. We found that:

🎬 Hippocampal ripples mark event boundaries
🧩 Cortical ripples predict later recall

Ripples may help transform real-life experiences into lasting memories!

Movie-watching evokes ripple-like activity within events and at event boundaries

Nature Communications - The neural processes involved in memory formation for realistic experiences remain poorly understood. Here, the authors found that ripple-like activity in the human...

Finally,😃 the first project during the Ph.D. program is published in PLOS Biology. We examined the spatiotemporal brain dynamics of context and sensory information integration in pain.

Hi, I’m very pleased to share my social memory project with my PI Won Mok Shim and amazing collaborators @myoo.bsky.social

How does the hippocampus integrate multiple cognitive processes for memory encoding and retrieval?🧠

Here’s what we found⬇️:

Coordinated representations for naturalistic memory encoding and retrieval in hippocampal neural subspaces - Nature Communications

In this study, the authors show that novelty encoding aligns with memory formation in the hippocampus but not with memory retrieval, and that hippocampal components involved in each process reflect it...

We then examined how the hippocampus interacts with cortical regions at event boundaries and sequence integration.
Two distinct systems emerged:
💚Hippocampus–PMC: supports content encoding
💜Hippocampus–vmPFC: supports event sequencing

Participants watched a scrambled movie while undergoing #fMRI, then recalled the story in its correct order.
We assessed two key memory processes:
💾 Content encoding
🧩 Event sequencing

🧠📖 New paper out! How does the brain make sense of a story?

Combining behavioral data, #fMRI, and #LLMs, our study explores how distinct hippocampal-cortical systems support the #encoding and #sequencing of #narrative events during ongoing comprehension.

New preprint out! 🚀
Our latest work on Motion-Corrected Eye Tracking (MoCET) is now available on bioRxiv! We introduce a method to improve gaze accuracy in fMRI experiments using head motion correction.

Check it out here: doi.org/10.1101/2025...

#EyeTracking #fMRI

Motion-corrected eye tracking (MoCET) improves gaze accuracy during visual fMRI experiments

Human eye movements are essential for understanding cognition, yet achieving high-precision eye tracking in fMRI remains challenging. Even slight head shifts from the initial calibration position can ...
