Preserved temporal hierarchy but frequency-specific alterations in dynamical regimes of EEG microstate multimers during reversible unconsciousness.
Neuroimage February 4, 2026 Chun-Yan Wang, Dong-Dong Zhou
Employing a spectral analysis framework based on Chaos Game Representation (CGR), we investigated the multimer-based dynamics of EEG microstates across broadband and canonical frequency bands during reversible unconsciousness (anesthesia and sleep). Robust periodic components consistently emerged within microstate sequences across theta, alpha, beta, and gamma bands, persisting across distinct...
