Beyond the Forest and the Trees: Overlooking the Overlooked Terrain of Neural State Dynamics

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

Topographical polarity reveals continuous EEG microstate transitions and electric field direction in healthy aging

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

Effects of stimulus modality and response type on oddball stimulus discrimination using polarity-considered EEG microstate labeling

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

Whole-brain EEG dynamics depending on the stimulus modality and task requirements in oddball tasks

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.

Spatio-temporal "global" neurodynamics of the human brain in continuous and discrete picture:Simple statistics meet on-manifold microstates as multi-level cortical attractors

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