Commonality of neuronal coherence for motor skill acquisition and interlimb transfer

Published in Scientific Reports, 2025

This study identified common neural coherence patterns underlying both motor skill acquisition and interlimb transfer, suggesting shared neurophysiological mechanisms for these two motor learning processes.

EEG Activity Over Ipsilateral and Contralateral M1 During Simple and Complex Hand Tasks: Variations with Motor Learning

Published in Frontiers in Neuroscience, 2025

This study characterized EEG activity over ipsilateral and contralateral primary motor cortex during simple and complex hand tasks, revealing how motor cortex lateralization changes across motor learning.

Task-constrained self-initiated attention shifts are indexed by frontal-midline theta ramping

Published in Frontiers in Human Neuroscience, 2025

We investigated the EEG signatures of voluntary, self-initiated attention shifts during visual search. Frontal-midline theta oscillations showed a characteristic ramping pattern prior to attention shifts, reflecting the cognitive demands of self-initiated attentional control.

Physics-Aware Video Instance Removal Benchmark

Published in CVPR 2026 Workshop on Video Generation and Beyond Evaluation (VGBE), 2026

We introduce PVIR, a benchmark of 95 videos with a decoupled human evaluation protocol that reveals current video instance removal methods still treat object erasure as 2D texture filling rather than physics-aware scene reconstruction, particularly failing on complex physical side effects like reflections and shadows.

WMF-AM: Probing LLM Working Memory via Depth-Parameterized Cumulative State Tracking

Published in arXiv preprint, 2026

We introduce Working Memory Fidelity-Active Manipulation (WMF-AM), a probe of cumulative state tracking that isolates within-pass cumulative load by parameterizing depth K. Testing 20 open-weight models (0.5B–35B) across 13 families, our probe predicts agent performance with r = 0.612 (p < 0.001).

Self-initiation of attentional shift during visual search

Published:

Oral presentation at the European Conference on Visual Perception (ECVP) 2023. This talk presented EEG and eye-tracking evidence for the neural mechanisms underlying self-initiated attentional shifts during free visual search. We characterized the temporal dynamics of oscillatory activity preceding voluntary attention shifts and discussed implications for models of endogenous attentional control.

Exploring Mechanisms of Self-initiated Attention Shifts: Analysis of Theta Wave

Published:

Poster presentation at the 16th Asia Pacific Conference on Vision (APCV 2024). This work presents a theta oscillation analysis of EEG data recorded during self-initiated attention shifts in a visual search task. Frontal-midline theta power showed systematic ramping prior to voluntary saccades, linking preparatory neural dynamics to the initiation of attention shifts.

EEG-Based Decoding of Voluntary Attentional Control: Differentiating Self-Initiated Shifts in a Visual Search Paradigm

Published:

Poster presentation at the joint EPC (European Conference on Eye Movements) and APCV (Asia Pacific Conference on Vision) 2025 meeting. We demonstrated EEG-based multivariate decoding to differentiate self-initiated attention shifts from externally driven shifts in a visual search paradigm, revealing distinct temporal dynamics in voluntary attentional control.
