The paper evaluates if multidimensional scaling (MDS) provides a valid low-dimensional representation of whole-body movements by analyzing exercise categories versus performer identity.

This study examines how whole-brain activity patterns change with increasing WM load across an extended N-back task, revealing nonlinear changes in network similarity and semantic representations.

This paper redefines EEG microstate analysis by shifting from template-based clustering to landmark-based state definitions, improving analytical performance and reproducibility.

This study introduces a compact multimodal EEG-fMRI framework to assess cognitive domains and demands, showing consistent behavioural and neural patterns across modalities.

This study examines age-related differences in EEG microstate transitions and electric field direction by analyzing topographical polarity and transition probabilities.

This study evaluates polarity-considered EEG microstate labeling for classifying oddball stimuli in auditory-visual tasks, showing improved classification accuracy with decision-tree models.

This study examines how stimulus modality and task requirements affect whole-brain EEG dynamics during oddball tasks, revealing links between microstate transitions and attentional processes.

This study investigates how dual-site tACS modulates BOLD signals in real-time, showing propagation across the whole brain through specific spatiotemporal patterns.

The paper visualizes global neural dynamics across EEG, fMRI, and MEG using manifolds and microstates, showing continuous and discrete representations of brain activity.

The paper investigates the sense of agency over speech, identifying two components: action-outcome causality and self-voice identity, and their roles in speech perception.

The paper investigates how perceptual generation, not termination, infers self-agency in time perception through seven experiments with 90 participants.

This study identifies neural representations for sensorimotor error, feeling of agency, and judgment of agency in the human brain.
