The paper uses a portable three-channel EEG system to decode futsal free-kick outcomes from pre-movement brain activity, finding session-specific neural signatures linked to performance.

The paper designs and validates a portable EEG electrode holder for accurate motor-related EEG measurement in real-world settings.

This study examines how sleep-wake schedules affect performance, physiology, and psychology in early and late chronotypes, finding distinct patterns based on preferred sleep timing.

This study identifies neural correlates of reward-based motor learning, finding that FRN amplitude predicts learning efficiency while alpha ERD predicts retention, with no interaction with reinforcement conditions.

This paper demonstrates that integrating large language models with neural and oculomotor signals improves BCI control accuracy for selecting arbitrary posts in a social networking service.

This study shows that closed-loop neurofeedback training during motor imagery enhances somatosensory cortex activity and improves keyboard typing performance.

This study shows that posture affects motor maps in marmoset monkeys' primary motor cortex, with hindlimb posture having a strong influence, while body angle does not.

The paper addresses two common issues in synchronized multimodal EEG recordings: jitter and latency, using a Lab Streaming Layer-based system for precise time alignment.

This study shows that de novo brain-computer interfaces (BCIs) alter the neural manifold of motor cortex activity during learning, with fixed classifiers stretching the manifold and adaptive classifiers preserving its structure.

This study uses spatially bivariate EEG-neurofeedback to show participants can manipulate interhemispheric inhibition in sensorimotor activity.

This paper conducts a meta-analysis of BCI-based post-stroke motor rehabilitation, finding a medium to large effect size on motor improvement.
