How does the brain🧠 make causal inferences and use memories to understand narratives🎬?

We built an RNN🤖 with key-value episodic memory that learns causal relationships between events and retrieves memories like humans do!

A neural network with episodic memory learns causal relationships between narrative events

Humans reflect on past memories to make sense of an ongoing event. Past work has shown that people retrieve causally related past events during comprehension, but the exact process by which this causa...

Preprint⭐
Our attention changes over time and differs across contexts—which is reflected in the brain🧠 Fitting a dynamical systems model to fMRI data, we find that the geometry of neural dynamics along the attractor landscape reflects such changes in attention!

Geometry of neural dynamics along the cortical attractor landscape reflects changes in attention

The brain is a complex dynamical system whose activity reflects changes in internal states, such as attention. While prior work has shown that large-scale brain activity reflects attention, the mechan...

Alert!!!!

“An Action Networks Model for Pain”

We propose a new model for chronic pain — and highlight two functionally connected cortical networks that could revolutionize how we treat it.

Does your favorite song actually relieve pain?
We looked into the brain to find out. 🧠🎶❓

🧠📖 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.

Our new @NatureHumBehav paper shows why we need a holistic pain biomarker framework. ML on blood tests, brain/bone imaging & genetics predicts clinical diagnoses but falls short on subjective pain. Adding psychosocial (mood, sleep, stress) boosts both. shorturl.at/vxxeO

Biological markers and psychosocial factors predict chronic pain conditions - Nature Human Behaviour

Fillingim et al. show that biological and psychosocial factors jointly predict conditions associated with chronic pain.

Dreaming of a dataset that tracks mood, sleep & activity to better understand affective instability (AI)…AND paired with advanced MRI? 🤯

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...

😄The final version of my first Ph.D. project is published in PLOS Biology. We showed the spatiotemporal profile of how the brain mediates cue-stimulus integration in pain, interpreting the findings in terms of cortical hierarchy from association to sensorimotor systems. plos.io/4fsaanu

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.
