Abstract

The human brain exhibits ongoing large-scale network dynamics even in the absence of external stimuli, reflecting the continuous nature of thought and consciousness. Electroencephalography (EEG) microstates transient, quasi-stable topographical patterns lasting 60–120ms have been proposed as the “atoms of thought,” representing building blocks of spontaneous mental activity. Four canonical microstate classes (A, B, C, and D) have been consistently identified across individuals, each linked to distinct functional networks.
