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.

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

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.
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.
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.
