Research Interests

I am broadly interested in how neural representation and computation govern cognition and affect. My goal is to uncover the computational mechanisms shared across biological and artificial systems. Previously, I was an fMRI guy who developed fMRI-based predictive models of pain with human brain representations. Currently, I am investigating the sense of agency in an artificial agent by using the PV-RNN algorithm, which combines predictive coding with variational recurrent neural networks. My focus is on how the sense of agency emerges from hierarchical generative models linking action generation and sensory prediction.

Decoding pain: uncovering the factors that affect the performance of neuroimaging-based pain models
Dong Hee Lee (Lead author), Sungwoo Lee, Choong-Wan Woo
PAIN, 2025  
paper / codes / commentary

This study shows a comprehensive overview about modeling targets and options of brain imaging-based pain predictive models through a literature review and benchmark analysis.

Interindividual differences in pain can be explained by fMRI, sociodemographic, and psychological factors
Suhwan Gim, Dong Hee Lee, Sungwoo Lee, Choong-Wan Woo
Nature Communications, 2024
paper

As a commentary paper for Hoeppli et al. (2022), this paper examined that a multiple regression model including brain imaging, sociodemographic, and psychological measures could predict individual differences in pain self-report. We also identified brain regions associated with these differences using fMRI data.

Functional brain reconfiguration during sustained pain
Jae-Joong Lee, Sungwoo Lee, Dong Hee Lee, Choong-Wan Woo
eLife, 2022
paper / codes

This study explored dynamic changes in functional brain networks during pain in the mouth, which provides new insights into how dynamic interactions between brain systems organize and modulate the experience of pain.

Individual variability in brain representations of pain

Nature Neuroscience, 2022
paper / codes

This study identified different brain representations of pain processing across brain regions. Some brain regions such as vmPFC show high variability across individuals, whereas other regions such as SMC show stable patterns.

Human-like shifts in the sense of agency within computational models
Dong Hee Lee (Project Leader), Lingwei Zhu, Yukie Nagai
in analysis

Can artificial neural networks replicate human-like shifts in sense of agency in response to sensorimotor conflicts? If so, are the shifts in sense of agency asymmetric between gaining and losing controllability? We address this question through PV-RNN and robot arm data.
