Abstract:
Electroencephalography (EEG) is a powerful tool for investigating brain electrophysiology with high temporal resolution. In recent years, advancements in EEG signal analyses have expanded our research capabilities. Among these, microstate analysis has emerged as a promising approach, providing insights into the topographical distribution of EEG signals and capturing millisecond-scale brain network dynamics. This technique offers a window into the intrinsic activity of large-scale neural networks. A hallmark of disorders of consciousness (DoC) is the disruption of brain activity dynamics. Research shows that EEG microstate analysis can deeply assess the consciousness level and neural mechanism during recovery process in DoC patients, demonstrating significant value in diagnosis and prognosis evaluation of DoC. This article reviews the principles and parameters of microstate analysis, the correlation between microstates and brain networks, and the parameter changes under different states of consciousness, and explores its application value in the diagnosis, classification and prognosis assessment of DoC, with the aim of providing new ideas for DoC precise diagnosis and treatment.
