Electroencephalography (EEG) microstate analysis is a whole-brain imaging technique that can characterize the organization and temporal dynamics of large-scale cortical activity with high temporal resolution [1]. The concept for the microscopic state of EEG comes from the discovery that broad-band spontaneous EEG activity at rest can be described with a limited number of scalp potential topographies, which remain quasi-stable for a specific length of time before rapidly changing into a new map configuration [2].
